事件響應(yīng)鏈的傳播路線：

initial view –> super view –> …..–> view controller –> window –> Application –> AppDelegate

UIResponse的觸碰方法：

/**** 觸摸事件方法，對(duì)觸摸事件進(jìn)行處理 *****/-(void)touchesBegan:(NSSet*)touches withEvent:(nullableUIEvent*)event;//觸摸開始-(void)touchesMoved:(NSSet*)touches withEvent:(nullableUIEvent*)event;//觸摸移動(dòng)-(void)touchesEnded:(NSSet*)touches withEvent:(nullableUIEvent*)event;//觸摸結(jié)束-(void)touchesCancelled:(nullableNSSet*)touches withEvent:(nullableUIEvent*)event;//觸摸取消

ios中主要的手勢(shì)：

1.UITapGestureRecognizer //單擊手勢(shì)

?點(diǎn)擊作為最常用手勢(shì)，用于按下或選擇一個(gè)控件或條目（類似于普通的鼠標(biāo)點(diǎn)擊）

/**

添加點(diǎn)擊手勢(shì)

*/-(void)addTapGestureWithTarget:(id)sender{//1,tap(點(diǎn)擊)UITapGestureRecognizer*tapGesture=[[UITapGestureRecognizer alloc]initWithTarget:selfaction:@selector(tapGestureAction:)];//手勢(shì)點(diǎn)擊次數(shù)tapGesture.numberOfTapsRequired=1;// Default is 1//點(diǎn)擊手指數(shù)量tapGesture.numberOfTouchesRequired=1;// Default is 1//將手勢(shì)識(shí)別器添加到view上[sender addGestureRecognizer:tapGesture];}/**

2.UIPanGestureRecognizer //拖動(dòng)手勢(shì)

拖動(dòng)用于實(shí)現(xiàn)一些頁面的滾動(dòng)，以及對(duì)控件的移動(dòng)功能。

/**

添加拖拽手勢(shì)

*/-(void)addPanGestureWithView:(id)sender{//2,pan(平移)UIPanGestureRecognizer*panGesture=[[UIPanGestureRecognizer alloc]initWithTarget:selfaction:@selector(panGestureAction:)];panGesture.minimumNumberOfTouches=1;//最少點(diǎn)擊次數(shù)---[sender addGestureRecognizer:panGesture];}/**

3.UISwipeGestureRecognizer //輕掃手勢(shì)

橫掃手勢(shì)用于激活列表項(xiàng)的快捷操作菜單

/**

4.UIPinchGestureRecognizer //捏合手勢(shì)

即放大縮小

/**

添加捏合手勢(shì)

*/-(void)addPinchGestureWithView:(UIView*)aView{//4,pinch捏和UIPinchGestureRecognizer*pinchGesture=[[UIPinchGestureRecognizer alloc]initWithTarget:selfaction:@selector(pinchGestureAction:)];[self.pinchImg addGestureRecognizer:pinchGesture];}/**

5.UIScreenEdgePanGestureRecognizer//邊緣滑入

滑動(dòng)用于實(shí)現(xiàn)頁面的快速滾動(dòng)和翻頁的功能。

/**

6.UIRotationGestureRecognizer //旋轉(zhuǎn)手勢(shì)

即將視圖圍繞中心點(diǎn)轉(zhuǎn)動(dòng)

/**
