如何制作& quot; suckEffect""在iPhone的左上角? [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，如何看到我编写的一段代码使动画变得生动起来.当我在应用程序中按下删除按钮时，将发生"suckEffect".但它会出现在屏幕的左上角.我想问你，除了我的iphone屏幕的左上角，是否有人知道我该怎么做！

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

您可以使用未公开的 + [UIView setAnimationPosition:].请注意，suckEffect没有记录，Apple会拒绝使用它的应用程序.与 setAnimationPosition:相同.

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