UIView Animation isn't working

[UIView beginAnimations:nil context:UIGraphicsGetCurrentContext()];
[UIView setAnimationDuration:1.0];
[UIView setAnimationDelay:0.0];
[UIView s开发者_开发技巧etAnimationDelegate:self];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:viewHelp cache:YES];

[self.view addSubview:viewHelp];

[UIView commitAnimations];

Where am I doing wrong? I am able to switch the view but I am not able to animate it.

[self.view addSubview:viewHelp]; the animation is just literally adding the subview, you need to work out what animation you want, and then apply it by changing values in the views frame property.?
