推荐答案

您可以通过生成图像并将其添加到数组中来实现，这使得为图像设置动画或对图像执行任何操作非常容易.

You can do it by spawning an image and adding it to an array, which makes it extremly easy to animate the image or do whatever with it.

    - (void)createImage {

    UIImageView *Image = [[UIImageView alloc] initWithFrame:CGRectMake(arc4random() % 320, 480, 40, 40)];
    [Image setBackgroundColor:[UIColor blackColor]];
    [self.view addSubview:Image];
    [myArray addObject:Image];

}

这会在任何地方创建一个黑色图像并将其添加到数组中.

That creates a black image wherever and adds it to an array.

然后，您可以制作一个计时器并每秒生成一次图像！

Then, you can make a timer and spawn the image every second!

spawn = [NSTimer scheduledTimerWithTimeInterval:1.0/3 target:self selector:@selector(Spawn) userInfo:nil repeats:YES];


- (void)Spawn {

    [self createImage];

}
