Crashing with uncaught exception 'NSInvalidArgumentException'

[alexstuckey]

Hi,

I am changing views with this code:

//Loading old view
MainScreenViewController *mainScreenController = [[MainScreenViewController alloc]
 initWithNibName:@"MainScreenView"
													  bundle:nil];
self.mainScreenViewController = mainScreenController;
[mainScreenController release];
	
//Loading new view
CreditsViewController *creditsController = [[CreditsViewController alloc]
													  initWithNibName:@"CreditsView"
													  bundle:nil];
self.creditsViewController = creditsController;
[mainScreenController release];
	
//UIAnimation changing over the view
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:window cache:YES];
[mainScreenViewController.view removeFromSuperview];
[self.window addSubview:[creditsViewController view]];
[UIView commitAnimations];

But it crashes with this:

2010-01-14 12:32:18.154 AppName[10270:207] *** -[UIViewAnimationState view]: unrecognized selector sent to instance 0xf173f0

)

I do not know why this is happening?

Use the debugger and look in which line the error occurs.
That would be my first step.

Best Regards.

Thank you, I just tried it and using breakpoints I have found that the offending line is

[self.window addSubview:[creditsViewController view]];

Do you have any ideas what is going on?

I think your second release should be of creditsController not mainScreenController.

Thank you so much! I have been trying to fix that myself for hours. It is amazing how you overlook something when you look at it for too long!

Thank you again.

Alex.
