Answer 1

您可以使用 imageview 为图像制作动画。下面的代码是一个例子。这是一个简单的动画

  NSArray *imageNames = @[@"win_1.png", @"win_2.png", @"win_3.png", @"win_4.png",
                    @"win_5.png", @"win_6.png", @"win_7.png", @"win_8.png",
                    @"win_9.png", @"win_10.png", @"win_11.png", @"win_12.png",
                    @"win_13.png", @"win_14.png", @"win_15.png", @"win_16.png"];

NSMutableArray *images = [[NSMutableArray alloc] init];
for (int i = 0; i < imageNames.count; i++) {
    [images addObject:[UIImage imageNamed:[imageNames objectAtIndex:i]]];
}

// Normal Animation
UIImageView *animationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(60, 95, 86, 193)];
animationImageView.animationImages = images;
animationImageView.animationDuration = 0.5;

[self.view addSubview:animationImageView];
[animationImageView startAnimating];

// Slow motion animation
UIImageView *slowAnimationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(160, 95, 86, 193)];
slowAnimationImageView.animationImages = images;
slowAnimationImageView.animationDuration = 5;

[self.view addSubview:slowAnimationImageView];
[slowAnimationImageView startAnimating];
