Program received signal EXC_BAD_ACCESS : Simple Navigation

This is really basic. But I have no idea where I am going wrong.

I am on the ARC mode and all I have done is written the following code in my AppDelegate 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions function

    homePage *hp = [[homePage alloc] init];
    UINavigationController *navcon = [[UINavigationController alloc] initWithRootViewController:hp];

The home page gets loaded up correctly and there is a button on the homePage which when clicked should trigger a pressedPlay: wired up correctly in the .xib. But as soon as the button is clicked the program crashes with the error: EXC_BAD_ACCESS. Any help please?

I found a fix to the problem. With ARC the view to be pushed into the navigation controller must have a strong property associated with it, otherwise it is released.

Try this

homePage *hp = [[homePage alloc] initWithNibName:@"homePage" bundle:nil];
UINavigationController *navcon = [[UINavigationController alloc] initWithRootViewController:hp];

And follow naming conventions instead of homePage it should be HomePage.

This usually means something had a reference count of zero and then you tried to use it.

I bet it is something to do with whatever your button touch event is trying to process. Step through the code and see exactly at what point the crash happens.
