Question

I display a UIAlertView above my cocos2d layer.

I release it after I how it.

Is it really gone? Do I have to somehow remove it from my UIView?

Answer 1

If you just do

UIAlertView* alert = [[UIAlertView alloc] initWithTitle...];
[alert show];
[alert release];

then there’s no need to worry about it. However, if you set the alert’s delegate to some object, make sure that object still exists when the user taps a button in the alert – otherwise your app will crash when the alert will try to call alertView:didDismissWithButtonIndex: delegate method.
