UIKit之UIGestureRecognizer

   // 手势识别器
   // 7 个子类 : 轻拍手势 . 平移手势 . 轻扫手势 . 缩放手势 . 旋转手势 . 长按手势 . 以及 屏幕边界平移手势
   // 1. 轻拍手势
   UITapGestureRecognizer*tap  = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapAction:)];
   // 往相应的控件上添加手势
    [self.rootV.Imv addGestureRecognizer:tap];
   // 连击次数
   //tap.numberOfTapsRequired = 2;
   // 点击手指数
   //tap.numberOfTouchesRequired = 2;
   // UIImageView的用户交互默认是关闭的 需要打开
   self.rootV.Imv.userInteractionEnabled=YES;
   // 2. 长按手势
   UILongPressGestureRecognizer*longTap = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(longTapAction:)];
   // 设置最短长按时间
    longTap.minimumPressDuration= 0.01;
    [self.rootV.Imv addGestureRecognizer:longTap];
   // 3. 旋转手势
   UIRotationGestureRecognizer*rotation = [[UIRotationGestureRecognizer alloc]initWithTarget:self action:@selector(rotationAction)];
  // [self.rootV.Imv addGestureRecognizer:rotation];
   // 4. 捏合手势
   UIPinchGestureRecognizer*pinch = [[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(pinchAction:)];
    [self.rootV.Imv addGestureRecognizer:pinch];
   // 5. 平移手势
   UIPanGestureRecognizer*pan = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(panAction)];
   //[self.rootV.Imv addGestureRecognizer:pan];
   // 6. 轻扫手势
   UISwipeGestureRecognizer*swipe = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeAction)];
   //[self.rootV.Imv addGestureRecognizer:swipe];
   // 7. 屏幕边缘轻扫手势
   UIScreenEdgePanGestureRecognizer*screenEdge = [[UIScreenEdgePanGestureRecognizer alloc]initWithTarget:self action:@selector(screenEdgeAction)];
    //[self.rootV.Imv addGestureRecognizer:screenEdge];

UIImageView加载动图

// 1. 声明属性
@property(nonatomic,retain)UIImageView*Image;
// 2. 初始化
self.Image = [[UIImageView alloc]initWithFrame:CGRectMake(50, 100, 158, 212)];
    self.Image.backgroundColor = [UIColor whiteColor];
    [self addSubview:self.Image];
// 3.使用
NSMutableArray *imageArr = [NSMutableArray array];
    for (int i = 1; i < 19; i ++) {
            NSString *name = [NSString stringWithFormat:@"%d.tiff",i];
            [imageArr addObject:[UIImage imageNamed:name]];
        }
// 设置动态图图片数组
        self.Image.animationImages = imageArr;
// 设置播放一次的时间
        self.Image.animationDuration = 0;
// 设置重复次数
        self.Image.animationRepeatCount = 0;
// 开始动画
        [self.Image startAnimating];
// 结束动画
//[self.Image stopAnimating];
