What is considered best practice for animating view transitions on the iPhone?
For example, the ViewTransitions sample project from apple uses code like:
CATransition *applicationLoadViewIn = [CATransition animation];
[applicationLoadViewIn setDuration:1];
[applicationLoadViewIn setType:kCATransitionReveal];
[applicationLoadViewIn setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]];
[[myview layer] addAnimation:applicationLoadViewIn forKey:kCATransitionReveal];
but there are also code snippets floating around the net that look like this:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.75];
[UIView setAnimationDelegate:self];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:myview cache:YES];
[myview removeFromSuperview];
[UIView commitAnimations];
What is the best approach? If you could provide a snippet as well it'd be much appreciated.
NOTE: I've been unable to get the second approach to work correctly.
