IPhone SDK developers...

Hi,
Is there a 'forum' located somwhere (anywhere!) in the "developer's connection" pages?
It seems odd to me that there is no forum for those of us developer types to talk with each other regarding iPhone SDK development.
For example it would seem silly to ask in THIS forum area (anywhere under the iPhone main heading) ...
"Where can I find anything in the SDK that allows me to see/modify/update the SYSTEM PREF Bundle??"
Is there an off-apple-site (usenet?) group anywhere for these kinds of questions?
thanks,
tob

IPHONE SDK FOR DEVELOPERS.

Hi Mates,
After many trials, I managed to download the iPhone SDK. I have the following folders :
AccelerometerGraph,
BubbleLevel,
CryptoExercise,
HelloWorld,
PVRTextureLoader,
SpeakHere,
TouchCells,
UICatalogue.
I am not sure if all the folders were downloaded well.
I have some problems to start. I have Windows Vista. Can the iPHone SDK run under Vista or does it require Mac OS.
Thanks to help.
Judex.

Thanks for the "friendly" note, but as a "friendly" reminder to you - this is a user to user help forum that is primarily composed of "average joe" users of the iPhone. And what I mean by that is, this is not a computer programmer's forum.
Nothing personal against the OP for this thread, but he missed the minimum system requirements for the SDK provided at Apple's website where the SDK can be downloaded. Based on this alone, and I could very well be wrong, but I venture to say that he is not a computer programmer, or is not a programmer by profession.
I certainly could have worded my reply differently to be 100% accurate in regards to technical details for the computer programmer and anal retentive type, which I venture to say these discussions are not primarily composed of.
I included the part about the iPhone running an optimized version of OS X in regards to Apple's minimum system requirements for the SDK primarily to keep it simple since I expected - "why doesn't Apple utilize resources to support Windows with the SDK?"
Most people who ask that question are not computer programmers as a hobby or by profession either.
To keep it simple for what is likely the majority here, which probably does not include many computer programmers by profession - Apple could port the SDK to Windows, but since Apple sells computers and other hardware including iPods and the iPhone, along with their own software, Apple chose to support an Intel Mac running Leopard only for the iPhone and iPod Touch SDK - with both the iPhone and the iPod Touch running an optimized version of OS X.
Thanks for the note and clarification.

IPhone SDK on Tiger

Ok, last night I downloaded the 2GB free iPhone SDK so I could start developing some small apps for the iPhone and iPod touch. After waiting 30 minutes for the download to complete I was finally ready to start. I double clicked the iPhone SDK icon only to see a very cruel and mean message come up which read the following "Couldn't open iPhone SDK. This package type requires Mac OS X 10.5." Why, in the world would Apple force people who want to develop for THEIR PRODUCTS use a operating system that they don't want to? I have OS X Tiger (10.4.11) and do not have Leopard yet. Is there a version for Tiger available?

Well, you see, the iPhone SDK is made for Xcode 3. Xcode 3 is only available for Leopard and it would take a very long time for Apple to re-develop it just for Tiger and it wouldn't be worth the effort since most of the developers have all the newest programs installed, including Leopard.
That's why!

IPhone SDK on Windows

Is there any talk of an SDK for Windows? I have been trying to get OS X 10.5 running on vmware for weeks now, without any luck (Probably due to the fact that I'm running on an AMD Athlon 64). Annoyingly, I got 10.4 to run fine but the SDK doesn't run on 10.4.
I would pay through the nose for a Windows iPhone SDK, and I'm not the only one out there.

The SDK is primarily for serious developers interested in developing an app to be available via the iTunes app store as a free or paid app. There is also a developer enterprise program for a company with 500 or more employees that is interested in developing and deploying proprietary in-house applications to authorized users in the company only.
Selling the SDK to Windows users for only $50 when becoming a registered developer costs $99 for the standard program and $299 for the enterprise program just for some that are interested in developing their own apps for their iPhone only, along with support cost for many of the Windows users that certainly would follow just so some Windows users can develop their own app for their iPhone which doesn't gain Apple anything? Along with the resources and cost involved with porting the SDK to Windows in the first place and following support cost, this would be a losing venture for Apple with nothing gained. The more quality apps made available via the app store is a potential gain for Apple - not from the sale of apps which is probably a break even, but from the availability of good apps over time that will likely help to increase iPhone and iPod Touch sales.
Just as the iTunes Store for the sale of music and video is designed and set up to be a break even for Apple with the profit gained from iPod and iPhone sales. Even though Apple develops and has their own OS and software, they are primarily a hardware company first and foremost, so computer sales will continue to be important. And with a Mac including an Intel processor, one can install and run Windows and Windows applications natively on a Mac for the best of both worlds if both are needed.
An Apple computer with an Intel processor is capable of running more applications than a Windows PC natively - all Windows applications and all OS X applications.
I am sure that anyone interested in serious development for the iPhone which the SDK is designed for already had a Mac, or purchasing at least a Mac Mini was not a big problem or a hinderance. And the same for a company with 500 or more employees that wants to make use of the developer enterprise program.
I believe Apple's pride and set ways are the main reasons they are not doing as well as they could be.
Apple is doing plenty well because they are profitable, which is most important. And doubtful that selling the iPhone/iPod Touch SDK for $50 to Windows users interested in developing their own app for their iPhone only would be a profitable venture - not with the upfront cost to port it to Windows and the resulting and ongoing support costs that wouldn't gain Apple anything in the long run, and this definitely would not help sell more Apple computers.

SDK Developers

I have been looking for Windows developers (c#/java) that have used and automated the Photoshop SDK. So far I have found only one company. Do you know of any reputable firms that can handle automation with the Photoshop SDK?

IPhone SDK - What is the equivalent of a combo box

I have a screen where there are quite a few items which are of the multiple-choice type. In other platforms i use a combo box (pick lists) to do this.
On the iPhone SDK the only thing that comes close is the UIPicketView which is ugly IMHO. it takes too much real estate and too heavy.
Is this is the only control available now?
Also does the UIPicker come with an associated control which will launch the picker? What i mean is on other platforms and on the web there is a text field with a button with a down arrow next to it. Clicking either on the text field or the down arrow drops the list down. Is there a similar control on the iPhone which when clicked launches the picker OR do i have to create a button or a custom view which will launch the picker?
Thanks for reading this and for your feedback.

I do not believe there is an equivalent of -D in the DB JVM, a possible solution is:
Load a properties file into the DB using Loadjava, then open this file from your Java code using Properties.load(), then iterate the properties calling System.setProperty().

Learning iPhone SDK - Trying to draw an image

Although I have programmed for Mac in the last years, I have never used Mac-specific technologies as Cocoa (I have programmed more in OpenGL, SDL, and the like).
Now I am getting started with the iPhone SDK. I'd like to do some OpenGL|ES stuff, but since it is not supported in the Simulator, and you need to join the Developer Program to test stuff on directly on the device (and admission of new members is closed right now), I am focused on other stuff right now, like using Core Graphics for drawing images on the iPhone.
My application is based on the Cocoa Touch Application template. I left the default code except for a few changes.
In file "UntitledAppDelegate.m", I have changed the method applicationDidFinishLaunching to:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
contentView = [[[MyView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease];
[window addSubview:contentView];
[window makeKeyAndVisible];
Then, in the MyView interface file (MyView.h), I have added the attribute "UIImageView* image;" to the class, which is declared as a property, and synthesized.
In the class implementation (MyView.m), I have changed the method initWithFrame to:
- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
self.backgroundColor = [UIColor darkGrayColor];
image = [self loadImageView:@"box01.png"];
[self addSubview:image];
return self;
loadImageView is a private method I have implemented as:
- (UIImageView *)loadImageView:(NSString *) imageName {
UIImage *img = [UIImage imageNamed:imageName];
UIImageView *theView = [[UIImageView alloc] initWithImage:img];
return theView;
Since I have loaded the UIImage, and initialized a UIImageView with it, and the image view is added as a subview of the main view attached to the window, I thought it should be everything needed to draw an image on the screen. But nothing is visible. The screen is simply black when I run this on the Simulator. It doesn't even set the background to dark gray.
So I need some help with this, I sure that anyone with experience in Mac programming will know how to help me.
Thank you in advance.

I removed the XIB file from the project, but that didn't help. It was a problem with my inexperience with Objective-C. When accessing class properties in a method of the same class, i was not putting "self." before the property (in C++ that's redundant). For example, in the line "window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];". After adding it, it works correctly.

IPhone SDK CodeSign Error: Redux (latest OS X update is broken)

This bug - http://discussions.apple.com/thread.jspa?threadID=1455699&start=0&tstart=0 - is back. My AdHoc project, which worked perfectly last week, has just stopped building, with this:
"object file format invalid or unsuitable"
As soon as I upgraded from 10.5.7 to 10.5.8, this bug appeared.
However, this bug was officially fixed in 10.5.7 - so, I'm guessing here, Apple has accidentally re-created it.
Unfortunately, I cannot add to the original post, because Apple has frozen the topic.
So, here's a new topic to ask if anyone else is having this problem, and what they did about it - is it exactly the same as the old bug? or is it different in some way?
I'm going to try some of the workarounds for the old bug - but hacking command line scripts isn't fun, and I'm worried I might break something even worse .

IPhone SDK 2.2 memory corruption

Hello. I'm working on an application for iPhone SDK 2.2 and seem to be having weird memory corruption problems. Not necessarily leaks because using Instruments shows my memory stamp never going above about 1.8 megs. The nature of the app is a database of animals so I'm constantly loading and unloading sounds and images. None of the objects are very large (at most I'll have 4 800k pngs loaded at once) and I've checked and rechecked my alloc/retain/release and everything is in order (hence no memory usage increase). However...after using the application for a while I'll notice strange behavior. For example:
1) we have a UILabel as the title for each page. After a while the font size of this will change.
2) I have several screens with a subclassed UIScrollView where images are loaded and then added to. The problem shows itself here by the images not showing up. there's no crash, stepping through the debugger shows that the image loads up fine, it's just that the image is not there.
3) I have a UILabel at the top of an animal description screen, which in the nib file is called "Animal Name" by default. This will change to show "Animal Name" at the top.
I've removed all audio in our latest build so that isn't the problem. What I'm starting to suspect is that altering anything defined in a nib file will cause corruption. For example, the UIScrollView is defined in the nib file, and I constantly am reassigning the contents of that with a UIImageView. This UIImageView is handled within the subview class like :
UIImageView *imgView = [[UIImageView alloc] initWithImage: [ UIImage imageWithContentsOfFile:[[NSBundle mainBundle ] pathForResource:imageToLoad ofType:@"png" ]] ];
imgView.tag = 50;
[self addSubview:imgView ];
[ imgView release ];
Then later when moving away from the screen I'll find that view's tag and remove it from the superview (since addSubView increases the retain count, the alloc+addSubView is cancelled by release+removeFromSuperView)
I can't explain why titles that are never changed would be affected, but it must somehow be related. What I'm wondering is: are there any known issues involving modification of the contents of objects defined in Nib files? Perhaps the memory allocated when initWithNibName is restrained, then any modification of objects allocated within it can cause corruption. I'm starting to think I should just alloc and free anything modified in code and skip using nib files altogether (I reset the text on buttons for example). If this is a known issue please let me know. I'll give you more information if I can.
Thank you

Just download the huge SDK package and install. No need to uninstall the old SDK.

Problem in set selectedTextcolor in uitableview cell in iPhone SDK 3.1.2

Hello,
I set selected text color in uitableview cell using cell.selectedTextColor = [UIColor whiteColor]; for iPhone SDK 2.2.1.
Now i use iPhone SDK 3.1.2, So for that i make change as per documentation for that i use textLabel properties. But selectedTextColor is not exit.
So Now for SDK 3.1.2 how to set selectedTextColor?..
Thank you.

The textLabel property is an instance of UILabel, so it has its own textColor, textAlignment, and font properties. E.g.:
cell.textLabel.text = @"foo";
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.textAlignment = UITextAlignmentLeft;
Hope that helps!

IPhone SDK : Communication between iPhone client and a remote server

Hi,
This is w.r.t iPhone Cocoa Touch native application.
i need to populate my application 's data from a remote application server ( which in turn connects to the database) . I require some tips in the communication between client sitting on the iPhone and the remote application server. I am planning to proceed in XML transaction way.
I referred the SeismicXML sample application provided by Apple. In this sample,client reads the physically existing xml file from @"http://earthquake.usgs.gov/eqcenter/catalogs/eqs7day-M2.5.xml"; and the client parses the xml file and display the content on the table view.
i have following 2 queries ,
1. I do not want to read from a physically present file,i want the data to be transferred on the go.
Means, request should be sent from the client to a application server and the server process returns the data in form of xml file ( but its not creating any physical xml file) .
Basically i am looking for request - response concept.
2. Can we call a java process(which returns xml data) running on a remote server from the cocoa touch client.? If not java process,what would be other best way...
i am going through the Apple provided frameworks. Do any of the iPhone SDK frameworks support this request? If some one has any idea on the above mentioned queries, pls help me.
any pointers will also be helpful.
It might be too early to talk about these,but i have to take some business decision related on this.
thanks in advance.

You already know how to send a string via HTTP Post? And you know how to make XML into a string? Put the two together.

Running iPhone SDK & Leopard on G4 1.42 emac?

Looking for a cheap entry point to get into developing apps for iphone. I can get the 1.42ghz G4 emac for $200 or G5 PPC 2.0ghz for $775.
I've read that the G4 will run leopard, but havent found anyone running leopard and iphone sdx on the G4. I'd like to try things out first on the G4, but is it going to be so unbearably slow that I'm going to regret taking the cheap way out? Thanks.

Further research has led me believe now that iPhone SDK will only run on Intel based machines. If that is indeed the case, neither machine will work for me.

IPhone SDK custom installation, what do I need?

FYI, I will be developing iPhone Apps only and don't want to install unnecessary things.
Options are:
Developer Tools Essentials (Required.)
iPhone SDK (Obviously need.)
System Tools (Do I need? It's checked by default.)
UNIX Development Support (Do I need? It's checked by default.)
Mac OS X 10.3.9 Support (Know I don't need, not developing anything for OS X, particularly not an old version.)
WebObjects (Do I need? It's NOT checked by default.)
Thanks.

Hi--
Welcome to the Apple Discussions.
System Tools (Do I need? It's checked by default.)
I would suggest "yes." That's the installer for the performance tools. Shark, especially, can be invaluable for profiling your code.
UNIX Development Support (Do I need? It's checked by default.)
I'd suggest "yes." It's command line tools you might want at some point (to help in automating builds, etc.). Some aspects of scripting with OS X can also be made easier if you have the UNIX dev support installed.
WebObjects (Do I need? It's NOT checked by default.)
Definitely not, that's a web application framework you'd use if you were building a web site.

How to switch between views in iPhone SDK

I have been tasked to learn the iPhone SDK. I know Actionscript, Javascript and some Java, but I cannot understand the iPhone SDK at all. I cannot understand the syntax or how the multitude of files work together. Also, there are no tutorials for complete beginners that show step-by-step what to do and why.
All I am trying to make is an application with a couple of views that change when the user touches a button. What is the easiest way to switch from one view to another?
Also, what is an AppDelegate? What is "synthesize"? What is "nonatomic,retain"? Why can't I write code like this... theButton.onClick=loadView("NewView");

Ok, you really need to read up some on how Objective-C and Cocoa work.
That said, If you make a new project in XCode using the "Utility" template, you can immediately run it and see a view transition (flip).
Ultimately, however, what you're looking to do is way beyond what you should be expecting to be to be able to do at this point. Programming a scripting language (Javascript, ActionScript) is much different than programming in C/C+/Objective-C/Objective-C+. While not directly applicable to the iPhone, you'll probably want to buy and read Aaron Hillegass' book "Cocoa Programming for Mac OX X 3rd Edition".
There is a tutorial on the iPhone Dev Center (log in, main page, bottom right, under "resource types", click "Guides", and look for "iPhone Application Tutorial" on the next page) that is worth reading.
