iphone - 在 xcode 中，如何使动画停止在图像上？

Question

我知道“nil”会在动画结束时清除 imageView。但有没有办法在其中一张图像上结束它呢？当我在末尾没有“nil”的情况下运行它时，这是一个可爱的错误。

imageView.animationImages = [NSArray arrayWithObjects:
                                           [UIImage imageNamed:@"image1.png"],
                                           [UIImage imageNamed:@"image2.png"],
                                           [UIImage imageNamed:@"image3.png"],
                                           [UIImage imageNamed:@"image4.png"],
                                           [UIImage imageNamed:@"image5.png"],
                                           [UIImage imageNamed:@"image6.png"],
                                           [UIImage imageNamed:@"image7.png"],
                                           [UIImage imageNamed:@"image8.png"],
                                           [UIImage imageNamed:@"image9.png"],
                                           [UIImage imageNamed:@"image10.png"],
                                   [UIImage imageNamed:@"image0.png"],nil];
       imageView.animationDuration = 0.50;
       [imageView setAnimationRepeatCount: 1];
       [imageView startAnimating];

我认为没有办法直接做到这一点，但你可以这样做:

//set your animationImages as stated in the question
[imageView setAnimationDuration:0.5];
[imageView setAnimationRepeatCount:1];
[imageView startAnimating];
[imageView performSelector:@selector(setImage:) withObject:theFinalImage afterDelay:[imageVIew animationDuration]];

基本上，您将运行一次动画，然后用最终的静态图像替换动画图像。
