自定义导航控制器内, 启用屏幕边缘返回手势

 /*
     统一设置返回按钮后,启用屏幕边缘滑动返回
        1,遵守协议 UIGestureRecognizerDelegate
        2,设置代理 self.interactivePopGestureRecognizer.delegate = self;
        3,实现代理方法
     -(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{
     
     return self.childViewControllers.count > 1;

自定义导航控制器内, 启用全屏返回手势

 /*
     统一设置返回按钮后,启用全屏滑动返回
     1,遵守协议 UIGestureRecognizerDelegate
     2,创建pan手势
     UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self.interactivePopGestureRecognizer.delegate action:@selector(handleNavigationTransition:)];
     //添加手势
     [self.view addGestureRecognizer:pan];
     
     3,设置代理
     pan.delegate = self;
     
     4,禁用屏幕边缘返回手势
     self.interactivePopGestureRecognizer.enabled = NO;
     
     5,实现代理方法
     -(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{
     
     //防止根控制器启用滑动返回
     return self.childViewControllers.count > 1;
     }
