如何停止的UIView动画 [英] How to stop an UIView animation

问题描述

我有几个的UIImageViews 中的的UIScrollView ，我想扭动，当用户长期presses其中之一。因此，类似的行为你当你长期preSS在您的iPad / iPhone菜单的图标。

所以，我有以下几点：

   - （无效）{startWiggling    对于（*的UIImageView中的TouchView [滚动视图的子视图]）{        [UIView的beginAnimations：@摆动背景：无];
        [UIView的setAnimationDuration：0.1];
        [UIView的setAnimationRepeatAutoreverses：YES];
        [UIView的setAnimationRepeatCount：FLT_MAX];        //摆动1度两面
        touchView.transform = CGAffineTransformMakeRotation（）;
        touchView.transform = CGAffineTransformMakeRotation（-0.0174532925）;        [UIView的commitAnimations];    }} - （无效）{stopWiggling
    的NSLog（@停止摆动）;
}
 

这工作正常。问题是...我怎样才能使它的停止扭动用户之后pressed一个按钮？我有一个按钮，并将其连接等，它是达到 stopWiggling 方法，所以这是很好。但如此...

1. 如何从这些的UIImageViews ？
删除动画的UIView

2. 我可以绑定这一行动给用户pressing其设备上的主页按钮？

解决方案

 ＃进口＆LT; QuartzCore / QuartzCore.h＆GT;
 

然后

  [myView.layer removeAllAnimations]
 

或

  [self.view.layer removeAllAnimations]
 

I have several UIImageViews within a UIScrollView that I want to wiggle when the user long-presses one of them. So similar to the behavior you get when you long-press an icon in your iPad/iPhone menu.

So I have the following:

- (void)startWiggling {

    for (UIImageView *touchView in [scrollView subviews]) {

        [UIView beginAnimations:@"wiggle" context:nil];
        [UIView setAnimationDuration:0.1];
        [UIView setAnimationRepeatAutoreverses:YES];
        [UIView setAnimationRepeatCount:FLT_MAX];

        //wiggle 1 degree both sides
        touchView.transform = CGAffineTransformMakeRotation();
        touchView.transform = CGAffineTransformMakeRotation(-0.0174532925);

        [UIView commitAnimations];

    }    

}

- (void)stopWiggling {
    NSLog(@"Stop wiggling");    
}

This works fine. The issue is... How can I make it stop wiggling after the user has pressed a button? I have a button and connected it etc and it's reaching the stopWiggling method, so that's fine. But so...

1. How do I remove the UIView animation from these UIImageViews?
2. Can I bind this action to the user pressing the home button on their device?

解决方案

 #import <QuartzCore/QuartzCore.h>

then

 [myView.layer removeAllAnimations];

or

[self.view.layer removeAllAnimations];
