重复的动画变量的次数 [英] Repeat an animation a variable number of times

问题描述

我想知道我怎么可以设置动画重复。需要由变量来确定重复次数。在下面的code，变量 INT NEWPAGE 应确定动画是如何经常​​重复。

我想这一点，但动画（其中采用了块动画）只执行一次：

 为（INT TEMP = 1;温度＆LT; = NEWPAGE;临时++）{
            [个体经营animatePage]
}
 

如果我code以下，它就像我想它，但是这是很难codeD（即动画将重复两次），我看不到如何改变的方式这个动画是如何经常​​在code执行和数量按我可变NEWPAGE：

  [UIView的animateWithDuration：0
                      延迟：0.1
            选项​​：UIViewAnimationOptionCurveEaseIn
             动画：^ {[个体经营animatePage];}
             完成：^（BOOL完）{[自animatePage];}];
 

我会为如何重复同样的动画的建议非常感激，而不必硬code我想重复这个动画的次数。

编辑：

我试图实现以下code，但只有一个动画实际上进行：

  [UIView的animateWithDuration：0
                          延迟：1
                        选项​​：UIViewAnimationOptionCurveEaseIn
                     动画：^ {                         [UIView的setAnimationRepeatCount：2];
                         [个体经营animatePage]                     }
                     完成：无];
 

解决方案

有同样的问题 - 你缺少an'UIViewAnimationOptionRepeat

这应该工作：

  [UIView的animateWithDuration：0
                      延迟：1
                    选项​​：UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionRepeat
                 动画：^ {
                     [UIView的setAnimationRepeatCount：2]; // **本应出现在块的开始**
                     [个体经营animatePage]                 }
                 完成：无];
 

奏效了我。

I was wondering how I can set an animation to repeat. The number of repetitions needs to be determined by a variable. In the following code, the variable int newPage should determine how often the animation is repeated.

I tried this, but the animation (which employs a block animation) was only executed once:

for (int temp = 1; temp <= newPage; temp++) {
            [self animatePage];
}

If I code the following, it works like I want it to, but this is hardcoded (i.e. the animation will be repeated twice) and I can't see a way of how to change the number of how often this animation is executed in code and according to my variable newPage:

[UIView animateWithDuration:0
                      delay:0.1
            options:UIViewAnimationOptionCurveEaseIn
             animations:^{[self animatePage];}
             completion:^(BOOL finished){[self animatePage];}];

I'd be very grateful for suggestions of how to repeat the same animation without having to hardcode the number of times I want this animation to be repeated.

EDIT:

I tried to implement the following code, but only one animation will actually be carried out:

        [UIView animateWithDuration:0
                          delay:1
                        options:UIViewAnimationOptionCurveEaseIn
                     animations:^{

                         [UIView setAnimationRepeatCount:2];
                         [self animatePage];

                     }
                     completion:nil];

解决方案

Had the same problem - you were missing an an'UIViewAnimationOptionRepeat'

This should work:

 [UIView animateWithDuration:0
                      delay:1
                    options:UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionRepeat
                 animations:^{
                     [UIView setAnimationRepeatCount:2]; // **This should appear in the beginning of the block**
                     [self animatePage];

                 }
                 completion:nil];

Did the trick for me.
