UITapGestureRecognizer+动画

创建一个手势操作

  UITapGestureRecognizer点击手势

  UILongPressGestureRecognizer长按手势

  UISwipeGestureRecognizer滑动手势

   UIPinchGestureRecognizer按捏手势

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(添加事件)];

        tapGesture.numberOfTapsRequired = 1;//需要点一下响应

        tapGesture.numberOfTouchesRequired = 1;//需要一根手指

        [self addGestureRecognizer:tapGesture];

//    添加滑动手势

    UISwipeGestureRecognizer *swipeG = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(gesture:)];

    swipeG.direction = UISwipeGestureRecognizerDirectionRight;

    swipeG.delegate = self;

    [_redView addGestureRecognizer:swipeG];

    //添加手捏手势

    UIPinchGestureRecognizer *pinchG = [[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(gesture:)];

    pinchG.scale = 20;

   [_redView addGestureRecognizer:pinchG];

    //添加旋转手势

    UIRotationGestureRecognizer *rotationG = [[UIRotationGestureRecognizer alloc]initWithTarget:self action:@selector(rotation:)];

    [_redView addGestureRecognizer:rotationG];

 

//旋转

-(void)rotation:(UIRotationGestureRecognizer *)gesture{

    _redView.transform = CGAffineTransformRotate(_redView.transform, gesture.rotation);

}

 

 //放大动画

   CABasicAnimation *scaleAnimation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];

    scaleAnimation.fromValue = @1;

    if (type == kAnimationTypeInner) {

        scaleAnimation.toValue = @3;

    }else{

        scaleAnimation.toValue = @2;

    }

//透明动画

CABasicAnimation *opacityAniamtion = [CABasicAnimation animationWithKeyPath:@"opacity"];

    opacityAniamtion.fromValue = @1;

    opacityAniamtion.toValue = @0;

//组动画，两个动画同时执行

CAAnimationGroup *group = [CAAnimationGroup animation];

    group.animations = @[scaleAnimation,opacityAniamtion];

    group.duration = 0.5;

    group.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];

    return group;
