How is an AppDelegate instanciated?
- by pwny
I have an iOS application for which I want to create a ViewController programmatically.
I started an empty XCode project and modified the main method so it looks like this
int main(int argc, char *argv[])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, @"MyAppDelegate_iPad");
[pool release];
return retVal;
}
The app is a Universal Application, MyAppDelegate_iPad is a subclass of MyAppDelegate, which is a subclass of NSObject <UIApplicationDelegate>.
My problem is that the applicationDidFinishLoading method I've overridden in MyAppDelegate_iPad is never called (break point on the first line never hits). The method looks like this
-(void) applicationDidFinishLaunching:(UIApplication *)application {
window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
if(!window)
{
[self release];
return;
}
window.backgroundColor = [UIColor whiteColor];
rootController = [[MyViewController alloc] init];
[window addSubview:rootController.view];
[window makeKeyAndVisible];
[window layoutSubviews];
}
I removed the line to link to a nib file from my plist file (I used to get the default "My Universal app on iPad" white screen) and now all that is displayed is a black screen. applicationDidFinishLoading is still not being called.
Am I doing something wrong? How should I properly create my AppDelegate instance?
