冻结动画的最后一帧新代码？

我正在尝试冻结动画的最后一帧。以下代码曾经有效，但是在更新到 iOS 后它不再有效。我怎样才能编写这段代码以使最后一个图像保留在屏幕上？

animation.animationImages = [NSArray arrayWithObjects:

                             [UIImage imageNamed:@"watermelondrop2.png"],

                             [UIImage imageNamed:@"watermelondrop4.png"],

                             [UIImage imageNamed:@"watermelondrop6.png"],

                             [UIImage imageNamed:@"watermelondrop8.png"],

                             [UIImage imageNamed:@"watermelondrop10.png"],

                             [UIImage imageNamed:@"watermelondrop12.png"],

                             [UIImage imageNamed:@"watermelondrop14.png"],

                             [UIImage imageNamed:@"watermelondrop15.png"], nil];

    animation.animationDuration = .8;
    animation.animationRepeatCount = 1;
    [animation startAnimating];
    [self playwatermelondropsound];
    [self.view addSubview:animation];
    animation.image = [UIImage imageNamed:@"watermelondrop16.png"];

I'm trying to freeze the last frame of an animation. The following code used to work, however after an update to iOS it no longer works. How can I write this code so that the last image stays on the screen?

animation.animationImages = [NSArray arrayWithObjects:

                             [UIImage imageNamed:@"watermelondrop2.png"],

                             [UIImage imageNamed:@"watermelondrop4.png"],

                             [UIImage imageNamed:@"watermelondrop6.png"],

                             [UIImage imageNamed:@"watermelondrop8.png"],

                             [UIImage imageNamed:@"watermelondrop10.png"],

                             [UIImage imageNamed:@"watermelondrop12.png"],

                             [UIImage imageNamed:@"watermelondrop14.png"],

                             [UIImage imageNamed:@"watermelondrop15.png"], nil];

    animation.animationDuration = .8;
    animation.animationRepeatCount = 1;
    [animation startAnimating];
    [self playwatermelondropsound];
    [self.view addSubview:animation];
    animation.image = [UIImage imageNamed:@"watermelondrop16.png"];

我花了 40 分钟来解决您的问题，而且非常简单：

有两种方法可以实现您想要的效果：

将您想要在屏幕上显示的图像设置为默认图像。

或者只是这样做，

//将最后一行移至第一行。  
Animation.image = [UIImage imageNamed:@"watermelondrop16.png"];
动画.animationImages = [NSArray arrayWithObjects:
                     [UIImage imageNamed:@"watermelondrop2.png"],
                     [UIImage imageNamed:@"watermelondrop4.png"],
                     [UIImage imageNamed:@"watermelondrop6.png"],
                     [UIImage imageNamed:@"watermelondrop8.png"],
                     [UIImage imageNamed:@"watermelondrop10.png"],
                     [UIImage imageNamed:@"watermelondrop12.png"],
                     [UIImage imageNamed:@"watermelondrop14.png"],
                     [UIImage imageNamed:@"watermelondrop15.png"], nil];

动画.animationDuration = .8;
动画.animationRepeatCount = 1;
[动画开始动画]；
[自玩西瓜滴声音]；
[self.view addSubview:动画];

猜猜它会开始工作，因为我已经测试过它。 :)

I spend 40 my minutes to resolve your problem, and it was just so simple:

There are two way you can achieve what you want:

Set the image you want on your screen as default image.

or just do this,

//make your last line to first line.  
animation.image = [UIImage imageNamed:@"watermelondrop16.png"];
animation.animationImages = [NSArray arrayWithObjects:
                     [UIImage imageNamed:@"watermelondrop2.png"],
                     [UIImage imageNamed:@"watermelondrop4.png"],
                     [UIImage imageNamed:@"watermelondrop6.png"],
                     [UIImage imageNamed:@"watermelondrop8.png"],
                     [UIImage imageNamed:@"watermelondrop10.png"],
                     [UIImage imageNamed:@"watermelondrop12.png"],
                     [UIImage imageNamed:@"watermelondrop14.png"],
                     [UIImage imageNamed:@"watermelondrop15.png"], nil];

animation.animationDuration = .8;
animation.animationRepeatCount = 1;
[animation startAnimating];
[self playwatermelondropsound];
[self.view addSubview:animation];

And guess what it'll start working, as I have tested it. :)

[self cleanStance];
NSArray *imageArray = [[NSArray alloc] initWithObjects:
                       [UIImage imageNamed:@"jump1.png"],
                       [UIImage imageNamed:@"jump2.png"],
                       nil];    
self.player.animationImages = imageArray;
self.player.animationDuration = 0.3;
//self.player.contentMode = UIViewContentModeBottomLeft;
[self.view addSubview:self.player];
[self.player startAnimating];


- (void)cleanStance {
[self.player setImage:nil];
self.player.animationImages = nil;

这

是显示图像跳跃的示例，这可能会帮助你

[self cleanStance];
NSArray *imageArray = [[NSArray alloc] initWithObjects:
                       [UIImage imageNamed:@"jump1.png"],
                       [UIImage imageNamed:@"jump2.png"],
                       nil];    
self.player.animationImages = imageArray;
self.player.animationDuration = 0.3;
//self.player.contentMode = UIViewContentModeBottomLeft;
[self.view addSubview:self.player];
[self.player startAnimating];


- (void)cleanStance {
[self.player setImage:nil];
self.player.animationImages = nil;

}

This is the example to show the image jumping i thick this may help u

你的代码对我来说看起来很好，除了当我这样做时，我通常设置 UIImageView 的 .image 属性 BEFORE 我告诉 UIImageView 开始动画。另外，将 [UIImage imageNamed:@"watermelondrop16.png"] 添加到 .animationImages 数组的末尾。也许这会解决你的问题。希望有帮助！
