冻结动画新代码的最后一帧？

Question

我正在尝试冻结动画的最后一帧.以下代码用于工作,但是在更新到iOS之后它不再有效.如何编写此代码以便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"];

我花了40分钟来解决你的问题,这很简单:

有两种方法可以达到你想要的效果:

1. 在屏幕上将您想要的图像设置为default图像.

2. 或者只是这样做,

   //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];
   

并猜测它会开始工作,因为我已经测试过了.:)
