iOS开发自定义侧滑返回

可以添加屏幕边缘pan手势
    UIScreenEdgePanGestureRecognizer *recognizer = [[UIScreenEdgePanGestureRecognizer alloc]initWithTarget:self action:@selector(paningGestureReceive:)];
    recognizer.delegate = self;
    [recognizer delaysTouchesBegan];
         //屏幕左侧边缘响应
    [recognizer setEdges:UIRectEdgeLeft];//或者使用recognizer.edges = UIRectEdgeLeft;
    [self.view addGestureRecognizer:recognizer];
