//    userInteractionEnabled叫用户交互。如果没打开的话没有办法通过手势方式和它进行交互

//    

//

    

    

//    1。 点击

    UITapGestureRecognizer *tap=[[UITapGestureRecognizeralloc]initWithTarget:selfaction:@selector(tapAction:)];

    

//   把手势添加到视图上去；

    

    

   [self.imageViewaddGestureRecognizer:tap];

//

//

//    内存管理

    

    [tap release];

//    触发方法需要点击几次，默认是1

    tap.numberOfTapsRequired=2;

    UILongPressGestureRecognizer *longPress=[[UILongPressGestureRecognizeralloc]initWithTarget:selfaction:@selector(longPressAction:)];

//    3.旋转手势

    [self.imageViewaddGestureRecognizer:rotation];

    

    [rotation release];

    

    

    

    4,,,捏合

    

    UIPinchGestureRecognizer *PinchGesture=[[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(pinchGestureActian:)];

    

    [self.imageView addGestureRecognizer:PinchGesture];

    

    [PinchGesture release];

    

    

    

    

    拖拽

    

    UIPanGestureRecognizer *uipan=[[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(uipanAc:)];

    

    

    [self.imageView addGestureRecognizer:uipan];

    [uipan release];

    

    

    

    6.轻扫手势

    

    UISwipeGestureRecognizer *swipe=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeAction:)];

    [self.imageViewaddGestureRecognizer:swipe];

    [swipe release];

    

    

    

    

    7 . 屏幕边界手势

    

    这个手势出现的最晚，7.0以后才出现

   UIScreenEdgePanGestureRecognizer

    

    

    

    给视图添加一个毛玻璃效果

    [view release];

    

    self.view.backgroundColor=[UIColorwhiteColor];

    

    

//    响应者链

    

    UITapGestureRecognizer *tap=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tap:)];

    [self.imageViewaddGestureRecognizer:tap];

    [tap release];

    

    UIButton *buttonFirst=[UIButtonbuttonWithType:UIButtonTypeSystem];

    

    buttonFirst.frame=CGRectMake(0,0,
100, 100);

    

    buttonFirst.backgroundColor=[UIColorredColor];

    

    [self.imageViewaddSubview:buttonFirst];

    

    [buttonFirst addTarget:selfaction:@selector(click:)forControlEvents:UIControlEventTouchUpInside];

    

    

    UIButton *buttonSec=[UIButtonbuttonWithType:UIButtonTypeSystem];

    

    buttonSec.frame=CGRectMake(100,250,
100, 100);

    

    buttonSec.backgroundColor=[UIColororangeColor];

    

    [self.imageViewaddSubview:buttonSec];

    

    [buttonSec addTarget:selfaction:@selector(click:)forControlEvents:UIControlEventTouchUpInside];
