UIImageView动画开始并且出现内存不足警告

Question

我的ImageView动画有问题。 在我的视图中，有10多个视图，每个视图都通过其标签值进行标识，并且我有UIImageView和UIButton 。 当点击一个按钮时，必须对该视图的特定图像进行动画处理。 如果还有其他动画图像，则必须停止。 这是我的代码：

-(void)makeAnimation:(UIButton *)sender {

UIView *tagView=(UIView *)[self.view viewWithTag:sender.tag];
UIView *next=nil;
UIView *previous=nil;


NSLog(@"%d",sender.tag);
for (UIImageView * imageview in [tagView subviews]) {
     if ([imageview isKindOfClass:[UIImageView class]]) {

        if ([imageview isAnimating]) {
            NSLog(@"Animation Happens");

        }

        else{

            imageview.animationDuration=2.0;

            imageview.animationImages=[animationArray objectAtIndex:sender.tag-1];
            imageview.animationRepeatCount=2;
            imageview.tag=sender.tag;
            [imageview startAnimating];
        }
    }

}
   next=(UIView*)[self.view viewWithTag:sender.tag+1];
    previous=(UIView*)[self.view viewWithTag:sender.tag-1];
    NSLog(@"NOT IDEA");

    [self previousview:previous nextview:next];
 }

-(void)previousview:(UIView *)previous nextview:(UIView*)next
{
for (UIImageView * imageview in [previous subviews]) {

    if ([imageview isKindOfClass:[UIImageView class]]) {

        [imageview stopAnimating];
        NSLog(@"PRREVIOUS");

              }

}

for (UIImageView * imageview in [next subviews]) {

    if ([imageview isKindOfClass:[UIImageView class]]) {

        [imageview stopAnimating];
        NSLog(@"NEXT");

     }
   }
}

现在我的问题是，当我一个接一个地选择四个以上的按钮时，我的应用程序崩溃并发出内存警告。

在运行时使用配置文件查找泄漏的确切位置，然后使用@autorelease {}手动处理内存，如下所示。

-(void)makeAnimation:(UIButton *)sender {
@autorelease{
UIView *tagView=(UIView *)[self.view viewWithTag:sender.tag];
UIView *next=nil;
UIView *previous=nil;


NSLog(@"%d",sender.tag);
for (UIImageView * imageview in [tagView subviews]) {
     if ([imageview isKindOfClass:[UIImageView class]]) {

        if ([imageview isAnimating]) {
            NSLog(@"Animation Happens");

        }

        else{

            imageview.animationDuration=2.0;

            imageview.animationImages=[animationArray objectAtIndex:sender.tag-1];
            imageview.animationRepeatCount=2;
            imageview.tag=sender.tag;
            [imageview startAnimating];
        }
    }

}
   next=(UIView*)[self.view viewWithTag:sender.tag+1];
    previous=(UIView*)[self.view viewWithTag:sender.tag-1];
    NSLog(@"NOT IDEA");

    [self previousview:previous nextview:next];
}
 }
