Swift之高仿QQ侧滑

侧滑是App开发中非常常见的功能,目前大部分App都有实现这个功能.

简单介绍一下这个QQ侧滑的实现的步骤
添加拖拽手势

 //添加拖拽手势
        let pan:UIPanGestureRecognizer = UIPanGestureRecognizer(target: self, action: "didPanEvent:")
        self.view.addGestureRecognizer(pan)

设置侧滑出来的view,view的宽高,则是滑出view的尺寸.

// 1. 获取手指拖拽的时候, 平移的值
        let translation:CGPoint = recognizer.translationInView(recognizer.view)
    // 2. 让当前控件做响应的平移
        
    recognizer.view!.transform = CGAffineTransformTranslate(recognizer.view!.transform, translation.x, 0);
     // ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

        UIApplication.sharedApplication().delegate!.window!!.subviews.first?.transform.tx = (recognizer.view?.transform.tx)!/3
        
    
         // 3. 每次平移手势识别完毕后, 让平移的值不要累加
        recognizer.setTranslation(CGPointZero, inView: recognizer.view)
        

设置侧滑动画的时间.

if (recognizer.state == UIGestureRecognizerState.Ended){
        UIView.animateWithDuration(0.2, animations: { () -> Void in
            
            if (recognizer.view!.frame.origin.x > KSCREEN.width*0.5) {
                
                recognizer.view!.transform = rightScopeTransform;

                UIApplication.sharedApplication().delegate!.window!!.subviews.first?.transform.tx = (recognizer.view?.transform.tx)!/3
                
            }else{
                
                recognizer.view!.transform = CGAffineTransformIdentity;

                UIApplication.sharedApplication().delegate!.window!!.subviews.first?.transform.tx = (recognizer.view?.transform.tx)!/3
                
            }

        })

仅仅添加了手势侧滑,部分功能还待于完善,本demo仅供个人学习
