使用90％的CPU的UIView动画 [英] UIView animation using 90%CPU

问题描述

您好我有动画这循环，但使用的是90％，我的iPhone的CPU处理，并且加热了电话。我做了什么错？

任何人都可以给我一些建议？

感谢

   - （无效）nextAnimation：（浮点）$ P $ {pviousWidth//循环图片
imageViewTop.image = imageViewBottom.image;
imageViewBottom.image = [imageArray objectAtIndex：[imageArray数]  -  1];[imageArray insertObject：imageViewBottom.image atIndex：0];
[imageArray removeLastObject]
imageViewTop.alpha = 1.0;
imageViewBottom.alpha = 0.0;[UIView的animateWithDuration：4.0
                 动画：^ {
                     imageViewTop.alpha = 0.0;
                     imageViewBottom.alpha = 1.0;
                     }
                 完成：^（BOOL完成）{
                     [个体经营nextAnimation：stringsize.width];
                 }
 ];
 

解决方案

您得到了在你一个无限循环code。你必须有一个退出的条件，以避免无限循环。静态计数器是零，运行一次加1，如果计数器>ñ退出。

hi i have animation which loop but are using 90% of my iphone CPU processing and are heating up the phone. what have i done wrong ?

anybody can give me some advise ?

thanks

-(void)nextAnimation:(float)previousWidth {

//picture loop
imageViewTop.image = imageViewBottom.image;
imageViewBottom.image = [imageArray objectAtIndex:[imageArray count] - 1];

[imageArray insertObject:imageViewBottom.image atIndex:0];
[imageArray removeLastObject];
imageViewTop.alpha = 1.0;
imageViewBottom.alpha = 0.0;

[UIView animateWithDuration:4.0
                 animations:^{ 
                     imageViewTop.alpha = 0.0;
                     imageViewBottom.alpha = 1.0;
                     } 
                 completion:^(BOOL  completed){
                     [self nextAnimation:stringsize.width];
                 }
 ]; 

解决方案

You got a infinite loop in you code. You must have a quit condition to avoid infinite loop. A static counter is zero, and run one time add 1, if counter > n quit.
