私人api實現刪除圖片時的動畫

//私人方法

[UIView beginAnimations:@"suck" context:NULL];

[UIView setAnimationTransition:103 forView:scrollView cache:YES];

[UIView setAnimationDuration:0.5];

[UIView setAnimationPosition:CGPointMake(280., 440.)];

[currentPhotoView removeFromSuperview];

[UIView commitAnimations];

scrollView 指的是 superView

currentPhotoView 指的是 subView

[UIView setAnimationPosition:CGPointMake(280., 440.)]
用於設定動畫的方向

注:需要用到的 Private Header
