使用图片组图实现GIF动画

NSMutableArray *imageArr = [NSMutableArray arrayWithCapacity:4];//装图片的数组

for (int i = 0; i < 4; i++) {

NSString *imageName = [NSString stringWithFormat:@"001%d",i];

UIImage *image = [UIImage imageNamed:imageName];

[imageArr addObject:image];

}

self.girlImage.animationImages = imageArr;

self.girlImage.animationDuration = 1.5;//动画时间

self.girlImage.animationRepeatCount = 0;//重复次数，0代表无数次

dispatch_async(dispatch_get_main_queue(),^{

[self.girlImage startAnimating];//开始动画

});
