Question

我有这个简单的功能，我对按钮动画进行评分，然后为每个按钮开始动画，但我不知道为什么只有一个按钮动画而不是其他点击的按钮，请帮助我这个

- (IBAction)startAnimation:(UIButton *)button {

    NSMutableArray* imagesArray = [[NSMutableArray alloc] init];
    for (int images = 0; images < 15; images++) {

        UIImage* buttonImage = [UIImage imageNamed:[NSString stringWithFormat:@"aaqqq00%02d.png", images]];
        [imagesArray addObject:buttonImage];
    }

    NSArray* reversedAnim = [[imagesArray reverseObjectEnumerator] allObjects];

    int buttonTag = button.tag;


    animButton.adjustsImageWhenHighlighted = NO;

    for (int images = 0; images < 15; images++) {

        UIButton *animButton = (UIButton *)[self.view viewWithTag:buttonTag];

        if (images <= buttonTag) {
            animButton.imageView.animationImages = imagesArray;
            [animButton setImage:
             [UIImage imageNamed:@"aaqqq0014.png"] forState:UIControlStateNormal];

        } else {
            animButton.imageView.animationImages = reversedAnim;
            [animButton setImage:
             [UIImage imageNamed:@"aaqqq0000.png"] forState:UIControlStateSelected];

        }
        NSLog(@"%@", animButton.imageView.animationImages);
        animButton.imageView.animationDuration = 1; //whatever you want (in seconds)
        animButton.imageView.animationRepeatCount = 1;
        [animButton.imageView startAnimating];
    }

}

您正在传递按钮，因此执行标记查找看起来毫无意义且容易出错（如果层次结构中有多个具有相同标记的视图）。

设置按钮图像视图动画图像（animButton.imageView.animationImages）然后在该设置之后单个图像（[animButton setImage:...）也毫无意义。

您的日志声明对动画图像的描述是什么？

UIImage动画不适用于所有Button
