Question

I’m working on an app, but when I switch from my first view to my second view (game level). The game breaks with:

@autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }

and with the alert Threat 1: signal SIGABRT.

I don’t know why, by my other views this code work but when I want to switch to this view it breaks down. My switching code is:

-(void)collision {

if (CGRectIntersectsRect(Redsquare.frame, Invisible.frame)) {
        Level2 *switchtosecondlevelchapter1 = [[Level2 alloc] initWithNibName:nil bundle:nil];

        [self presentModalViewController:switchtosecondlevelchapter1 animated:YES];
    }
}

I hope you can help me, i’m new to this.
Thanks in advanced!

Answer 1

Is your nib name for Level2 literally “Level2″… in that case you can provide nil to initWithNibName:
But also add break points and NSLog to debug and see where it is last called… for example you’re literal presentModalViewController: code might be fine…. but your CGRectIntersectsRect might be… off….
Is everything initialized/non-zero
