iphone - 卡住动画的最后一帧新代码？

Question

我正在尝试卡住动画的最后一帧。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"];

Answer 1

我花了 40 分钟来解决您的问题，而且就这么简单:

有两种方法可以实现您想要的:

1. 将您想要在屏幕上显示的图像设置为默认图像。

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];
   

猜猜它会开始工作，因为我已经测试过了。 :)
