Xcode UIViewController
So I am brand new to development. Currently in school for software development and we're just getting started on iOS. In Xcode the book is telling me to create a new file and select UIViewController, but this is not showing as an option. It just gives me ObjectiveC class, etc. I used Objective C class and then selected UIViewController from there and it only gave me a .h and .m file. To create the .xib file I had to go through the same process and click View in User Interface options. Now the issue seems to be that they are not connected, and I cannot figure out how to connect them. Any help out there would be greatly appreciated! Btw, I'm developing for iOS 6 with the latest version of Xcode.
You need to state what Xcode version you are using, and be more specific about the instructions and what is going wrong. In Xcode 4.x, if you have already created your view controller class, you connect it to the view controller on the storyboard/xib by selecting the view controller, showing the Identity Inspector, and selecting the view controller class name from the Class dropdown.
In this picture, I have set the class associated with view controller to MasterViewController.

Hi all, i'm new to Mac book & Xcode. I'm learning and facing problems while creating a new file for Xcode. Before i upgrade the software, i have no issue to create simple steps in apps. After upgrade Xcode to 4.6 version, i'm facing lot's of issue eg.
1) "the identity "iphone developer" doesn't match any valid certificate/ private key pair",
2) can't select the box "with XIB for user interface" if the subclass is "UIViewController"..
Appreciate for any help rendered.Mikko777 wrote:So what is the best?
I wouldn't judge. I've been to Arch for a week, you know? But as said, it's VERY close to it.
What I dislike after a week is makepkg not handling dependencies automatically (which would be overhead, so probably not appropriate).

Don't actually need that as said ... I see no real benefit of having that other than not beeing a KDE user or having Gentoos useflags.

How to create a calendar using Xcode 4.5
I am new to xcode and trying to create a calendar in one of the tabs in a tab based application. I dont know what needs to be added in the view area, but from my searching net I have come to know that using eventkit.h one can create a calender. So I added Eventkit.framework in my Framework folder.
Then in calendarviewcontroller.h
#import <EventKit/EventKit.h>
#import <UIKit/UIKit.h>
@interface CalenderViewController : UIViewController
@end
and in .m I somehow found out to insert following
-(IBAction)AddEvent:(id)sender{
EKEventStore *eventDB = [[[EKEventStore alloc] init] autorelease];
EKEvent *holidayEvent = [EKEvent eventWithEventStore:eventDB];
holidayEvent.title = [self.item customValueForKey:@"title"];
holidayEvent.startDate = startDate;
holidayEvent.endDate = endDate;
holidayEvent.allDay = YES;
[holidayEvent setCalendar:[eventDB defaultCalendarForNewEvents]];
NSError *error;
[eventDB saveEvent:holidayEvent span:EKSpanThisEvent error:&error];
if (error == noErr)
[self sendDidFinish];
return NO;
else
[self sendDidFailWithError:error];
but I dont know what needs to be added before this code in .m file.
Kindly suggestfrom my searching net I have come to know that using eventkit.h one can create a calender. So I added Eventkit.framework in my Framework folder.
That code fragment does not create a calendar, it adds a calendar event to the default calendar.
If you need a visual calendar control, Cocoa does not include that. Various 3rd-party controls are available to provide a calendar UI. I recommend selecting one based on your specific requirements. For example, this one has a similar appearance to the Calendar app.
https://github.com/klazuka/Kal
You probably have two broad requirement areas: (1) Manage the calendar and event data, which can be done with Event Kit. (2) The user interface to view the calendar and event data, which can be custom developed, optionally using a 3rd-party library. Be sure to fully understand your requirements before selecting a 3rd-party control.
If you are a new Objective-C developer, expect a learning curve. -
XCode 4.4.1 is crashing on my 10.8.1 Mountain Lion Build
I created a small project called "CloudBuilder" and I following along with my standford IPhone Class.
I actually used all XCode versions ince 3.2 and I appailed that XCode is still crashing.
Before you Apple FanBoys jump in and ssay it not happening to you, keep in mind I getting XCode crashin on
every version of XCode I used so its defiantly not an install issue.
I running on a top of line MacBook Pro 8 GB memory Core i7 with 512 GB SSD so hardwrae is nice.
YES I have delete the two preferences files and reboot and rerun XCode (same issue)
This is a bug in XCode pr maybe the IOS SDK.
It happens whn I in IB and I dragging controls on the view. When I flip between an IBOutlet and an IBAction
XCode freaks out and crashes sometimes. The bug seems intermediate and I cannot replicate it often,
I keep closing XCode and delete preference files and rebooting.
Yes, I installed the command line tools from 10.8.1 and the updated 10.8.1 Core Data library
Eventually its goes away but will reappear later when my project gets bigger.
Here the console output
Anybody else seeing this?

I narrowed down the issue to do with CloudStorage (NSUbiquitousKeyValueStore)
Guys,
I seriously think this is a new issue occuring after the update of 10.8.1 (MacBookPro Retina) with XCode 4.4.1
So here goes...
_ubiquity = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];
_defaults = [NSUserDefaults standardUserDefaults];
// if ubiquity is available - use it !
if (_ubiquity) {
_cloudStore = [NSUbiquitousKeyValueStore defaultStore];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(storeDidChange:) name:NSUbiquitousKeyValueStoreDidChangeExternallyNotificationobject:_cloudStore ];
[_cloudStore synchronize];
Later on in the code (someplace else)....
- (void) setDateOfBirth:(NSDate *)dateOfBirth
if (self.isCloudEnabled) {
[_cloudStore setObject:dateOfBirth forKey:@"dateOfBirth"];
} else {
[_defaults setObject:dateOfBirth forKey:@"dateOfBirth"];
[_defaults synchronize];
(_defaults is a NSUserDefaults object FYI - see above code seg)...
So when the line (_cloudStore setObject...) occurs, 4 seconds later i receive a crash....

Installation Directory in Xcode 4
I'm writing Mac app for my own use only.
I keep in certain folder all my AppleScript Editor apps and run them from there.
"Xcode also has an Installation Directory build setting that lets you install a build product in a specific location. The Installation Directory is in the Deployment collection."
How i tell Xcode 4 to put working copy of app to this custom folder without moving any stuff in DerivedData folder?
I can't have any DerivedData stuff in this folder, because it would mess my workflows.
Thanks1st. create a new viewController in your storyboard.
2nd. create new file that's called objective-C Class, choose a name for your class (example SecondViewController) and make sure that you have selected UIViewController.
If you have created that file go to you SecondViewController.m, and scroll down to
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
Delete: return (interfaceOrientation != UIIinterfaceOrientation PortraitUpsideDown);, and put in state of that: return YES;
Dont forget to link up that SecondViewController to your new viewController in storyboard.
I hope that this will solve your problem. -
Am making an iPhone app and I am new to Xcode and IOS programming - whenever I run the app in the simulator and tap on the button which sends me to the next view it crashes and gives me this message:
In the debugger it gives me this:
2014-02-26 19:42:25.396 ShoeForYouStoryboard[2452:70b] -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x8c79730
2014-02-26 19:42:25.400 ShoeForYouStoryboard[2452:70b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x8c79730'
*** First throw call stack:
Thanks if you can help.Your app is using auto layout, which was introduced in iOS 6. Your iPhone is running iOS 5, which doesn't support auto layout. That's why the code works on your iPad, but not your iPhone.
If you want your app to work on both devices you have to turn off layout and set your app's deployment target to iOS 5. To turn off auto layout, select your xib file from the project navigator. Open the file inspector by choosing View > Utilities > Show File Inspector. Deselect the Use Auto Layout checkbox.
To change the deployment target, select your project from the project navigator to open the project editor. Select your project from the left side of the project editor. Click the Info button at the top of the editor. Choose iOS 5.0 from the iOS Deployment Target combo box. -
Xcode debugger not showing my instance variables!!
I hate asking questions like this.
I set a breakpoint in an IBAction method 'pushed:' inside FooViewController. At runtime I pressed a GUI button and processing stopped in pushed:.
In the data-viewing pane of xcode, I see
{code}
self = (FooViewController *) 0x... etc.
{code}
Indented under this is
{code}
UIViewController = (UIViewController) { ...
{code}
Nowhere do I see any of my instance variables!!
Now, they were synthesized from properties, but that doesn't matter, does it?
The code that proceeds to set some instance variables runs fine.
Why isn't xcode displaying self's instance vars?
Thanks,
ChapYes, yours looks like I was expecting mine to look.
Note that viewDidLoad (below) does work correctly, producing the expected results in the simulator!
Hangman3ViewController.h:
@interface Hangman3ViewController : UIViewController {
@property ( nonatomic ) NSInteger wordLength;
@property ( retain, nonatomic ) NSString *alphabet;
@property ( nonatomic ) unichar guess;
@property ( nonatomic ) NSInteger guessNo;
@property ( retain, nonatomic ) NSMutableString *board;
@property ( retain, nonatomic ) IBOutlet UILabel *boardLabel;
@property ( retain, nonatomic ) IBOutlet UILabel *guessNumberLabel;
@property ( retain, nonatomic ) IBOutlet NSArray *keyboardButtons;
- (IBAction)letter:(id)sender;
- (void)showBoard;
@end
and, Hangman3ViewController.m:
#import "Hangman3ViewController.h"
@implementation Hangman3ViewController
@synthesize wordLength = _wordLength; // preprocessor command to gen getter/setter and instance variable
@synthesize boardLabel = _boardLabel; // preprocessor command to gen getter/setter and instance variable
@synthesize guessNumberLabel = _guessNumberLabel; // Guess #n
@synthesize keyboardButtons = _keyboardButtons; // array of buttons
@synthesize alphabet = _alphabet; // A-Z unichars
@synthesize guess = _guess; // unichar
@synthesize guessNo = _guessNo; // int
@synthesize board = _board;
- (IBAction)letter:(id)sender
Get letter from sender - driven when key button is pressed.
The button's tag is an int from 0-25, identifying what letter of the alphabet it is.
Extract that unichar from ALPHABET as 'guess'. Then, disable the button,
which has been defined to have its text turn white (invisible) when disabled.
UIButton *button = (UIButton *)sender;
self.guess = [self.alphabet characterAtIndex: button.tag];
NSLog(@"Received keystroke: %C", self.guess);
[button setEnabled:NO];
- (void)showBoard
self.boardLabel.text = self.board;
self.guessNumberLabel.text = [NSString stringWithFormat:@"Guess #%d", self.guessNo];
- (void)dealloc
[_boardLabel release];
[_guessNumberLabel release];
[_keyboardButtons release];
[super dealloc];
- (void)didReceiveMemoryWarning
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
#pragma mark - View lifecycle
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad
NSLog(@"Hello from viewDidLoad");
[super viewDidLoad];
self.alphabet = @"ABCDEFGHIJKLMNOPQRSTUVWXYZ"; // unichar string
self.wordLength = 7; // temp - will be set from flipside later on
self.guessNo = 1;
[self.board setString:@"_______"]; // actually dynamic based on wordLength
self.board = @"_______";
[self showBoard];
- (void)viewDidUnload
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);

How socket communication is possible in Xcode?
Hi all,
I am trying to connect with a server (local host itself) using NSStream in Xcode 3.2.3.
I refered the below link: http://www.raywenderlich.com/3932/how-to-create-a-socket-based-iphone-app-and-se rver
I had implemented a separate view control and nib file and did whatever discussed in that site.
We have implemented the code for input and output streams, and port opened by calling the method specified in that site.
The new nib was called using :
LoginViewController *objView = [[LoginViewController alloc] initWithNibName:"LoginViewController" bundle:nil];
The nib connection was done because I cheked "with XIB for user interface" when the UIViewController Class was added.
But the app was hanged for no reason.
When an existing nib was called instead, it was loaded successfully(no socket concepts implemeted).
Is it because of the code, the app hanged...?
Is there any way to test whether the port was opened for input stream successfully..?
I would appreciate if anyone give a step by step explanation for accomplishing the socket connection...
Also it would be very helpful if somebody could share the code snippets.By issuing "recover database" Oracle read information from redo log files and applied them to datafiles. There was SCN difference between Control File and datafiles. All your changes made to database was in redo log files and "Database buffer cache", but wasn't due to power outage database buffer cache was cleared. So your data was not added to datafiles, but was in redo log files. By issuing "recover database" you Oracle applied all changes from redo log files to datafiles and successfully recovered the database

Hello,
im new to Xcode and have (i think) a simple question. I want to open a new window by pressing a simple push button. I know how to do that. My problem is, that i want to bind it to a condition. When i press a button, there should be a check: for example if textfield 1 = "test123" and textfield 2 = password, then open window x.
So im just missing the command for opening a windowThis is for iOS but the idea should be similar for OS X:
.h
@interface myViewController : UIViewController <UITextFieldDelegate>
UITextField *aTextField;
-(void)buttonPressed;
@property (nonatomic, retain) UITextField *state;
.m
@implementation myViewController
@synthesize aTextField;
-(void)loadView
UIView *view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"An Image.png"]];
self.view = view;
[view release];
self.view.frame = CGRectMake(114, 212, 540, 620);
aTextField = [[UITextField alloc] initWithFrame:CGRectMake(70, 230, 80, 22)];
[self.view addSubview:aTextField];
self.view.userInteractionEnabled = YES; -
IPhone SDK 2.0 - xcode fails to build new project
I downloaded and installed the latest iPhone 2.0 SDK. I did not uninstall any previous tools (xcode/SDK). I assume the 2.0 SDK installation will perform the upgrade in a proper fashion (not requiring one to uninstall the previous SDK/xcode). I start up xcode. I check the version via the about menu. It states that the version of xcode is 'Version 3.1 (Beta)'. The project settings indicate that the Base SDK is Device - iPhone OS 2.0. I checked my system to ensure that my current filesystem has the correct SDK. It has the Macintosh HD->iPhoneOS.pltaform->Developer->SDK's->iPhoneOS2.0.sdk.
OK, everything seems good up to this point. I create a new xcode application for the iPhone. I then go to compile the application and I get the following error:
/Developer/iPhone Examples/Foo/Classes/FooAppDelegate.h:16: error: syntax error before 'UIToolbarController'
Source code line : UIToolbarController *toolbarController;
Yes I realize that the UIToolbarController API has been removed for SDK 2.0. However, how can one use xcode to build a starter application if it is generating code that references outdated API's???
Am I doing something wrong? I have searched all the forums but have not come across this issue. Hence, I think something is wrong with my setup/install. If the solution is not to use UIToolbarController API, then why does the xcode still use it to build starter code projects? Also, if we can't use the API, what is it's replacement?
thanksIt created more errors, as there are a whole lot of other API's
that have changed (UIViewController now doesn't resolve
some of it's members, e.g. toolbarItem).
Err... hello? Someone just told you what the names have changed to!
Wow. I have about 1 months worth of work, that I am going to
have to seriously think about throwing away because of all of
these growing pains.
Can't talk about the iPhone SDK specifically, but Xcode in general has great refactoring tools that will make the name changes, in all locations, in a split second for you. No, lets not get hysterical. It's not one month's work at all. It's not even five seconds work.
I think the newer 2.0 release is causing more problems than solutions.
That's the whole point. It's not a release. It's a beta. That's what happens with beta's. That's why you sign an NDA (non-disclosure agreement), stating that under no conditions will you discuss the SDK with anyone, and that you agree that things may change without prior notice or even break down completely.
Basically shutting down all of my development efforts.
Errrr.... hello again? -
Loading particle emitter from .sks file in Xcode 5
I have created a particle effect (which is in my project as a .sks file) in Xcode 5, and have added the SpriteKit framework to my project.
I'm having problems actually getting it to integrate/show in my UIViewController though.
I want to create a snow effect as the top view of my View Controller...No luck though!
I have used the following code in my .m file
- (SKEmitterNode *) snowEmit
NSString *snowPath = [[NSBundle mainBundle] pathForResource:@"Snow1" ofType:@"sks"];
SKEmitterNode *snow = [NSKeyedUnarchiver unarchiveObjectWithFile:snowPath];
return snow;
Does anyone know of any sample projects/tutorials/code or have any tips on how I can get this working?
Many Thanks!Cp5 and Cp5.5 both use .cptx file ending, but the two are not the same. If you open a Cp5 file in Cp 5.5 and then save it, you will see a warning dialog telling you that once you DO save it, you won't be able to open it again in Cp5.
Compatibility Mode has nothing to do with whether the file is Cp5 or Cp5.5 format: http://windows.microsoft.com/en-US/windows-vista/Make-older-programs-run-in-this-version-o f-Windows -
Xcode 4.1 crashing when moving files
Upgraded to Lion(so far I love it) all my software is up to date, and updated Xcode to 4.1, now when I open a current project and want to move my files around to be more organized I cant, and it crashes. Anyone else have this problem? or is there a solution coming soon?
Same thing since lion install with xCode 4.2. The following steps make it happen for me every time:
1. Create a new UIViewController subclass with File > New
2. Using the Project Navigator, drag the files from the root folder to a subfolder.
Brings up a message saying there's an "Inconsistent state" and crashes.

Running Xcode 3.2.3 for the first time, hitting an error immediately
Hello. I'm learning Objective-C from a book ("Beginning Mac Programming"), and I've run into an error right out of the gate. I've checked the book's errata, as well as left a message with the author, but neither have solved the issue.
Here's what happened:
1. I installed Xcode 3.2.3 (I'm on 10.6.4)
2. Opened it
3. Selected "New Project"
4. Application->Cocoa Application
5. Save app location to my user directory
6. Hit "Build and Run"
I haven't touched any code at all, yet I get the following error:
Build TextApp of project TextApp with configuration Debug

Command /Developer/usr/bin/gcc-4.2 failed with exit code 1
Any suggestions? I'm completely new to this, so I have absolutely no clue what to do next. The error command seems to be looking in the "developer" directory, although the code is saved in my user directory.
Any help would be greatly appreciated.
Thank you.The /Developer directory contains the compiler(s) and various tools and libraries.
Does your user account name really contain a single quote? If so, it looks like the quote is getting eaten by one of the build scripts, which is resulting in a file path that doesn't exist.
