制作一系列动画来爆炸.将它们添加到UIImageView并开始动画.像这样:

Make a series of images that animate the explosion. Add those to a UIImageView and start the animation. Something like this:

UIImage *image0 = [UIImage imageNamed:@"explosion0.png"];
UIImage *image1 = [UIImage imageNamed:@"explosion1.png"];
UIImage *image2 = [UIImage imageNamed:@"explosion2.png"];
UIImage *image3 = [UIImage imageNamed:@"explosion3.png"];

myImageView.animationImages = [NSArray arrayWithObjects:image0, image1, image2, image3, nil];
[myImageView setAnimationDuration:0.75f];

[myImageView startAnimation];
