Using suckEffect

The most SDK-compatible way of using suckEffect is to use animation blocks. But the suction point by default is close to nowhere. Therefore you still need to use the undocumented method +[UIView setAnimationPosition:]:

[UIView beginAnimations:@"suck" context:NULL];
[UIView setAnimationTransition:103 forView:myViewContainer cache:YES];
[UIView setAnimationPosition:CGPointMake(12, 345)];
[myView removeFromSuperview];
[UIView commitAnimations];
