Interface builder freeze on compilation

I have never been able to get iPhone applications compiling on my Macbook Air.. Now I decided that I want to find out why.. So I have spent the most of the day trying some of the fixes suggested on the net. But nothing works.
I am trying to compile "WhichWayIsUp" demo, but once the .xib file starts compiling the process just hangs there.
Also if I try to open the .xib in Interface builder, interface builder gives me the spinning ball
I hope that some of you experts out there can help me out?
My crash log looks like this:

The general approach at this time is to ask if you've checked for any problematic fonts (all languages) with Apple's Font Book (look in the Applications folder). Find and remove all duplicates also.
Start there to be sure all fonts that are in play come out with a clean bill of health.
Don't hesisate to perform wholesale deletion of old and/or little used fonts - be skeptical of anything that has come from Office 2008, including those related to an Equation Editor installation.
By all means be sure any 3rd party apps are Snow Leopard compatible.
You can help to focus the problem by creating another user account named testUser and seeing if the problem still occurs there - this will help to identify if the issue is particular to your original account or system wide.
You can try deleting these plist files (~yourUserName/Library/Preferences):
• com.apple.InterfaceBuilder3.LSSharedFileList.plist
• com.apple.InterfaceBuilder3.plist
If you still have issues, consider asking again on the developer forums...

Good luck in any case.

So does that folder exist? It does on my disk.
I assume you have tried a Product > Clean then Build.

Xcode 4.2.1 crashes when using a QCView in Interface Builder

Hi, I have been trying to use a QCView in one of my projects but I get a crash everytime. I tried loading the QuartzComposerChart sample application but if I compile the project I get a crash, it just seems to crash when it wants to but I was able to get it compiled if I didn't click on the .nib file. It seems to be related to interface builder anyway.
Adding a QCView to a new project results in a .xib file not being able to be saved I get this error
The document “MainMenu.xib” could not be autosaved. -[NSConcreteMapTable state]: unrecognized selector sent to instance 0x402d47420

Thanks

Glad you posted... I am getting similar messages in xcode 4.2.1
The document “MainMenu.xib” could not be saved. -[DVTFileSystemVNode state]: unrecognized selector sent to instance 0x40540f920
I didn't make the connection with QCView until I saw your post. I have several .xib in the project with QCViews and all of them have this same problem. .xib files without QCViews in them are fine.
However, my application does not crash, but runs fine. (The xib's and application were written with xcode 3.2, and I can't edit them now in 4.2.1, because I can't save them. )
Any other clues would be welcome.
Thanks
Keith

Interface builder is unable to open documents of type iPad XIB

Hi,
I got a application from my teammate, and it is for both iphone and ipad devices (which it is developed under iPhone SDK 3.2).
I have iPhone SDK 3.1.3 installed in my mac book. When i tried to compile the application for iphone simulator i got the following error.
Interface builder is unable to open documents of type iPad XIB.
The above error is for interface builder created for ipad.
My Question is we can't compile the application on iPhone SDK 3.1.3 which the application developed under iPhone SDK 3.2?
Please shed some light of this?
thanks

Go to your project settings, and delete the line that says Interface Builder Plugin search path or something similar.
the exact line in project.pbxproj is: IBC_PLUGIN_SEARCH_PATHS = "${PROJECT_DIR}/**";

What can I do ? Thank you very much!!!

I found this on stack overflow.com and thought it would apply to this article discussion for some users even though I don't understand how to revert the version (through git?)
I think this is a compatibility issue. I think the .xib has moved to Xcode 4 (as shown by the line setenv IBC_MINIMUM_COMPATIBILITY_VERSION 4.2) which Xcode 3.2's version of ibtooldoes not understand.
I think you need to revert to a version of the .xib prior to the update to Xcode 4.""

Interface Builder ( IB ) font bug?

I noticed in ib, if i choose arial and then bold face (for labels, titles etc) it displays the text properly and is the proper bold. but when i deploy the app the text is gone, what i find wierd is in ib if you choose fonts that are not on iphone the text itself looks like it is the default font (eg. it doesnt let you use none iphone fonts)
so is this a bug with arial bold only?
i also tried to choose regular arial and then on the interface builder top menu i choose font >> bold and it turns the text bold, and it still doesnt display when compiled..
It makes no sense to me to have ib to do interface stuff when something like simple font choosing is buggy and/or not properly supported.

Human interface guidelines mandating a certain degree of consistency in appearance make a lot of sense, as would the fact that you cannot use fonts which are not available on the target system.
Arial is a horrible ripoff of Helvetica anyway.

Interface Builder and subclassing

Is it possible for me to have the outlet in Interface Builder pointing to a superclass... then in the code using that interface to point to a subclass?
So for example, suppose I'm setting up an interface in Interface Builder with a HumanView (let's say this is a subclass of UIView)... suppose this is like a character in an MMORPG... and you're customizing your chaacter...
and correspondingly in my code I have:
IBOutlet HumanView *character;
But I'm uncertain whether this view will be a female or male character... In my code I have two subclass of HumanView... FemaleView and MaleView... each with its own unique instance variables and methods...
Is it possible for me to decide in the program to have make "character" a FemaleView or MaleView?
Thanks.

Not a problem. I did realize I should add one minor clarification.
1) You can cast a quadralateral to a square in one instance. When you know that actual object (the structure in memory) is a square.
So, to be complete, you can safely cast a the square to a quadralateral all day long -- you know that a square is always a quadralateral. But if you are going to cast the quadralateral to a square, you should make sure you actually have a square object. The compiler will let you do it (might show a warning), but you could end up trying to reference pieces of a square that may not actually be part of the actual object. aka (in pseudo code):
// no issues with these two alloc/inits
Quad *foo = (Quad *)[[Square alloc] init];
Quad *bar = (Quad *)[[Rectangle alloc] init];
// both would return 4
[foo numSides];
[bar numSides];
// if setSideLength is only a method on a Square, then
// first line works fine
[(Square*)foo setSideLength:20.0];
// this line, however, will likely give a compiler warning and then
// an EXC_BAD* error during runtime -- bar is not actually a square
// in memory, despite what you are telling the compiler
[(Square*)bar setSideLength:20.0];
I hope I didn't conuse the issue -- but wanted to clarify.
Cheers,

After upgrading to Mountain Lion, Interface builder starts up with an error every boot.

I've got a late 2008 Macbook Unibody 13", and a few months back I upgraded from Snow Leopard to Mountain Lion. Ever since the upgrade, at every boot up Interface Builder starts up with an error. I've just ignored it mostly, but now I'm getting annoyed with it. How can I find the programs that start up every boot to research this, or stop it from loading Interface Builder every time?

You have to delete it using the minus sign at the bottom. The check/un-check is for hiding items.

Load Class in Interface Builder 3

Hello,
i am trying to get started with Cocoa after having worked a while with Xcode & smaller AppleScript based projects.
As my idea was to create a menubar-based (NSStatusItem) service app for myself i started with this tutorial:
http://files.semaja2.net/NSStatusItem%20-%20ObjC.html
Unfortunaly it seems like there was a change in Interface Builder regarding loading Classes from Version 2 to IB version 3
The tutorial tells me to (about the middle of the tutorial):
Rename the “NSMenu1” to “StatusItem”, following this in “Interface Builder” >>choose from the menu “Classes > Read Files..” now select the AppController.h >>file, Once the file has been read it should change out project view to “Classes” >>from here find the AppController item and right click on it and select >>“Instantiate AppController”:
I was able to follow the tutorial until there without problems but it looks like the Classes-Tab is gone in IB 3.x.
So i feel somehow unable to finish this small tutorial.
how would i do this step in Interface Builder 3.x ?
Any help is heavily appreciated.
Best regards
fidel

You're right, this has changed. I'm currently using IB 3.1.1 but I believe the changes appeared in IB 3.
Once you've done the "Read class files" and selected your AppController.h file IB should know about your class.
In order to instantiate your AppController in IB first go to the Library window and find the "NSObject" (it will appear as a blue cube). Drag one of these NSObject's from the Library window and drop it into your MainMenu.xib window along with the other icons that appear there (File's Owner, First Responder, Application... etc).
Now you will have created an instance of an NSObject in your MainMenu.xib file. And, since your AppController class is a subclass of NSObject (and IB knows this since you've had it read in your AppController.h file) you can now change this NSObject instance into an instance of your AppController.
Select the NSObject icon in the MainMenu.xib window then go to IB's Inspector window and click on the next to last icon in the top tool bar. This should change the Inspector window's title bar to say "Object Identity" and the Class Identity in the first text field should be set to NSObject. You should be able to type "AppController" into this field (or click the popup and it should show up in the popup list. Once you've done this it will transform the NSObject instance into an AppController instance.
You'll see another slight difference between IB 3.x and the tutorial when you do the <Control>-Drag between items to connect up the outlets and actions. Instead of finalizing the connections in the Inspector window like the tutorial says you'll get a small popup window right next to the item you're connecting to that will list the available outlets/actions you can connect to. Simply click the one you want. You can still double-check your connections in the inspector window though.

Looking for simple sample of iphone apps without using Interface Builder

I successfully went through the 'iphone app tutorial' and used Interface Builder, but now want to try creating apps without it.
The UI Catalog sample is too complex, but didn't see anything that just had a view and a button or label.
Ideally I want code that doesn't require any IB usage, but I can't tell if that is possible yet...
Anyone have a link to an easy sample?
Or has anyone created a test app themselves and wouldn't mind posting?
I took a stab at creating one and posted it on the "101" forum, but it would be hard for somebody to try and figure out what I was attempting
Thx for any links/___sbsstatic___/migration-images/migration-img-not-avail.png
ps
I really need a good book, especially "cookbook" style

hey dear
I have one solution of your problem
just go to in iphone developer search for FAQ
In faq their is one section how to use prohramming in this you can see
the how to ceate label,button etc.
after that simply add the view or remove theview.

Cannot open nib - The application Interface Builder quit unexpectedly

Just installed the iPhone SDK and installed sample code. The Interface Builder will not start. At startup, the following message is displayed: "The application Interface Builder quit unexpectedly."
I've tried the standard Xcode SDK and it has the same problem. I've repaired permissions on the disk, to no avail. I'm stumped on this. Thanks for any suggestions.

Thanks for asking. It happens when I click the "Interface builder.app" name in finder and when I double-click an .xib file name in finder.
As I mentioned, I have repaired permissions on the drive to no avail. I have also read older posts on the web referring to various preference plist files but those don't exist with this build of xcode.
I have also had older builds of xcode on this mbp and worked thru a couple of tutorials. Interface Builder from those older builds worked. I'm not sure were to get them, now, and I doubt they would have the iphone sdk included.

How to instantiate a control in code instead of using Interface Builder ?

I really appreciate the combination of the interface builder and Xcode altogether.
However when I am learning QT, I realize I had been pampered by Apple's Design to a certain extend as I only need to create say a NSLabel instance and use Interface Builder to do the linking and never have to worry about instantiating the Object myself.
But I'm curious, what is the way to instantiate a new hmmm say...NSLabel in the code ?
NSLabel* label = new NSLabel();
Then what ?
What you are seeing here is how QT did it, could anyone create an equivalent in ObjC ? No fancy code please, just bare minimum.
#include <QApplication>
#include <QWidget>
#include <QLabel>
int main (int argc, char * argv [ ])
QApplication app(argc, argv); //NSApplication in ObjC
//These two lines merely created a window and set the title bar text.
QWidget* window = new QWidget();
window->setWindowTitle("Hello World");
QLabel* label = new QLabel(window);//Create a label and inform the it belongs to window.
label->setText("Hello World");
window->show();
return app.exec();

Hi Jack -
I think my best answer will be something of a disappointment, because I don't know how to show a one-to-one correspondence between the code you're working with and a Cocoa program. The main function of a Cocoa GUI program for OS X will look something like this:
#import <Cocoa/Cocoa.h>
int main(int argc, char *argv[])
return NSApplicationMain(argc, (const char **) argv);
As you commented, we could draw a correspondence between the first statements, but after that the functionality of the Cocoa program is going to be spread out in a way that makes for a rather tedious comparison. The only way I know to answer your question in less than 5000 words, is to skip ahead to one of several points in the startup sequence where the programmer can intervene with custom code.
For example, a common way to get control would be to program a custom controller class and add an object of that class to the main nib file which is loaded during the startup sequence. By making a connection to the Application object in that nib file, the custom object could be made the delegate of the Application object, and if we then added a method named applicationDidFinishLaunching, our code would run as soon as the application's run loop was started.
Now I finally have enough context to directly answer your question, so here is the code to create a label and add it to the key window at launch time:
// MyAppController.m
#import "AppController.h"
@implementation AppController
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
NSLog(@"applicationDidFinishLaunching");
NSRect frameRect = NSMakeRect(150, 300, 150, 30);
NSTextField *label = [[NSTextField alloc] initWithFrame:frameRect];
[label setEditable:NO];
[label setStringValue:@"Hello World!"];
[label setFont:[NSFont labelFontOfSize:20]];
[label setAlignment:NSCenterTextAlignment];
NSView *contentView = [self.window contentView];
[contentView addSubview:label];
@end
If I needed to develop a worst case scenario for this thread, the next question would be, "Ok sure, but your code still needs a nib to start up. I want to see a Cocoa GUI program that doesn't require any nib".
It turns out that it's quite easy to build a simple iPhone app without any nib, but it's considerably more difficult for an OS X app. If anyone wants to see my nib-less iPhone code, I'll be happy to post it (I think I did post it here once before, and the response was underwhelming). But I've never attempted the much more difficult nib-less OS X app. Just in case you really want to go there, here's a blog that goes into the details: [http://lapcatsoftware.com/blog/2007/07/10/working-without-a-nib-part-5-open-re cent-menu>.
Hope some of the above is helpful!

Interface Builder Error: Could not read archive

I created a new project in Xcode. I double click on MainWindow.xib and it opens up Interface Builder like it should, but then I get an error saying "Could not read archive". This happens every time with any project I have tried to start; please help.

I' ve the same problem. And if I make a new interface and save it, after a new klick on MainWindow.xib there's tthe error saying too.
Sorry for my bad Englisch, but I'm German.
