UIImage *spriteSheet = [UIImage imageNamed:@"sprite-sheet"];
NSMutableArray *contentRects = [NSMutableArray new];
NSMutableArray *durations = [NSMutableArray new];
for (int j = 0; j < 12; j++) {
   for (int i = 0; i < 8; i++) {
       CGRect rect;
       rect.size = CGSizeMake(img.size.width / 8, img.size.height / 12);
       rect.origin.x = img.size.width / 8 * i;
       rect.origin.y = img.size.height / 12 * j;
       [contentRects addObject:[NSValue valueWithCGRect:rect]];
       [durations addObject:@(1 / 60.0)];
   }
}
YYSpriteSheetImage *sprite;
sprite = [[YYSpriteSheetImage alloc] initWithSpriteSheetImage:img
                                                contentRects:contentRects
                                              frameDurations:durations
                                                   loopCount:0];
YYAnimatedImageView *imageView = [YYAnimatedImageView new];
imageView.size = CGSizeMake(img.size.width / 8, img.size.height / 12);
imageView.image = sprite;
[self.view addSubView:imageView];
```
