    Hey everyone,

    I was programming an iphone app when i realized my xcode version was kinda old. I upgraded to the iOS4 version now my application bugs immediately when it tries to start, without an error. I found the line in my application delegate where the crash may happen.

    [window addSubview:navigationController.view];

    If i comment the line, the app starts, without the navigationcontroller of course.

    If i try to catch the exception it still crashes without a line in my log. :S
    Code:
    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
    	@try {
    	[window addSubview:navigationController.view];
    	} 
    @catch(id exception) {
    		NSLog(@"D%@", exception);
    	}
        [window makeKeyAndVisible];
    	return YES;
    }
    I really can't see why it still crashes even if it is within a try, so i hope someone can help me out here.

    Thanks Chris :)

    Look at navigationController.view and see if it's been initialized or not. What does the debugger show? What does the crash report indicate?
