如何制作“suckEffect”在iPhone的左下角？ [英] How to make "suckEffect" to the left corner of iPhone?

问题描述

// Begin Animation "suckEffect".
CATransition* animation  = [CATransition animation];
animation.type           = @"suckEffect";
animation.duration       = 1.0f;
animation.timingFunction =  UIViewAnimationCurveEaseInOut;
myView.opaque            = 1.0f;
[myView.layer addAnimation:animation forKey:@"transitionViewAnimation"];

当我按下删除按钮时，你怎么看我编写一部分动画代码。当我在我的应用程序中按下删除按钮时，会发生suckEffect。但它会进入屏幕的左下角。我想问你是否有人知道我怎么能做这个效果，但我的iPhone屏幕的左角！

How you can see I write a part of code witch make an animated when I press delete button. When I press delete button in my application the "suckEffect" take place. But it goes to left corner of the screen. I want to ask you if anybody know how can I do this effect but for left corner of my iphone screen !!!

推荐答案

您可以使用未记录的 + [UIView setAnimationPosition：] 。请注意suckEffect未记录，Apple将拒绝使用它的应用程序。同样适用于 setAnimationPosition：。

You can use the undocumented +[UIView setAnimationPosition:]. Beware that the suckEffect is undocumented and Apple will reject apps using it. Same for setAnimationPosition:.
