开发中有时需求会要求滑动控制器直接返回 ，苹果自带效果只能在控制器的边缘处返回 现分享一种比较优雅的处理方法：
//找到原有的手势对象及实现方法 self.interactivePopGestureRecognizer.delegate\handleNavigationTransition
UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self.interactivePopGestureRecognizer.delegate action:@selector(handleNavigationTransition:)];
pan.delegate=self;
self.interactivePopGestureRecognizer.enabled=NO;
//给导航控制的View添加拖拽手势
[self.view addGestureRecognizer:pan];
}
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
//回到首页控制器时不用开启手势
return !(self.childViewControllers.count==1);
}
