在CATransition之后发布视图控制器：我这样做对吗？

Question

My application is loading a first view (used to login into a Web service). When the login is successful, it performs a CATransition (basic kCATransitionFromRight) to show a second view and hides the first view. I've set the delegate of the transition to self so I can use -(void)animationDidStop:(CATransition *)theAnimation finished:(BOOL)flag .

When that method is called (right after the transition is over) I want to release the first view since I won't need it anymore. However, when I call [firstView release] (in animationDidStop: ) the retain count doesn't seem to change. I used [loginView retainCount] to check this and since I know it's not always reliable I was wondering: am I doing this right?

Thank you.

Answer 1

taken from the book "Cocoa Touch for iPhone OS 3" is a similar approach.
They set up an animation remove the old subview, add the new one and then commit the animation.

Answer 2

Jilouc in his comment is right, forget to check "retaincount"...

if you want to be sure that your object view firstView just add a

NSLog(@"i'm removing myFirstView"); 

in its

-(void)dealloc{
}

method...

if you get that NSLog in debugger console window then be sure you had it removed/released in the right way...

btw... the right way could be something like this:

in animationDidStop:

if (firstView!=nil){
    [firstView.view removeFromSuperview];
    [firstView release];
    firstView=nil;
}
