UIImageView 內建動畫+N張圖片實現很炫的動畫，

gitHub上又看到個很炫的動畫：https://github.com/MartinRGB/GiftCard-iOS 看了看他的代碼，發現核心動畫（就是把按鈕封裝成一個禮物盒）其實很簡單，就是把一個動畫的一幀一幀都截取下來放到一個數組裡面，然後利用了UIImageView內建的可以播放一個image的數組的方法。簡化過的代碼大概是這樣子： - (void)viewDidLoad {    [super viewDidLoad];     NSMutableArray *array = [NSMutableArray array];    for (int i = 0; i < 40; i++) {
        UIImage *image = [UIImage imageNamed:[NSString stringWithFormat: @"gifbutton000%02d",i]];
        [array addObject:image];
    }
    self.giftImageArray = array;
    self.giftImageView.animationDuration = 1.0;
    self.giftImageView.animationImages = self.giftImageArray;
    self.giftImageView.animationRepeatCount = 1;
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleGiftImageViewTapped:)];
    [self.giftImageView addGestureRecognizer:tapGesture];
    self.giftImageView.userInteractionEnabled = YES;
    self.giftImageView.image = [self.giftImageArray firstObject];
   } - (void)handleGiftImageViewTapped:(UITapGestureRecognizer *)sender {
    [self.giftImageView startAnimating];
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        UIImage *image =  [self.giftImageArray lastObject];
        self.giftImageView.image = image;
    });}效果  方法雖然簡單，但是效果很贊，不知道有沒有更好的實現方式，但這起碼是一種實現方式，值得記錄一下！
