//1.创建一个存放图片的数组

NSString *imgName = [NSString stringWithFormat:@"%@_%02d",picName,i];
/*
通过imageNamed加载图片
优点：图片加载到内存当中后，下次调用时直接取出，无需加载，不会释放
缺点：如果需要加载的图片过多，会导致占用非常大部分的内存，甚至会直接被系统强制退出程序
*/
// UIImage *img = [UIImage imageNamed:imgName];
NSString *path = [[NSBundle mainBundle] pathForResource:imgName ofType:@"jpg"];
//通过图片路径取图片，需要传递一个图片的完整路径，适合加载大量图片
UIImage *img = [UIImage imageWithContentsOfFile:path];
[imgArr addObject:img];
}
//2.将图片存入到序列图片数组中
self.imgView.animationImages = imgArr;
//3.设置动画持续时间;
self.imgView.animationDuration = imgArr.count * 0.1;
//4.设置动画循环次数(默认为无数次)
self.imgView.animationRepeatCount = 1;
//5.开启动画
[self.imgView startAnimating];
//6.清空图片数组--performSelector方法：延迟执行；
// @selector(setAnimationImages:) 当这个方法启动后
// withObject: 设置为nil后，self.imgView中就被清空
// afterDelay：延迟时间
[self.imgView performSelector:@selector(setAnimationImages:) withObject:nil afterDelay:imgArr.count * 0.1];
