iOS禁用边缘侧滑返回

开发中，出于某种需求或者避免某个bug，会有要求某一个界面不能侧滑返回。这里给大家介绍一种简单的实现方法：

进入该页面时，关闭侧滑手势：

• (void)viewDidAppear:(BOOL)animated {
  [super viewDidAppear:animated];
  if([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
  self.navigationController.interactivePopGestureRecognizer.enabled = NO;
  }
  }
  进入下个页面或者返回上一个页面时，启用侧滑手势：
• (void)viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:animated];
  if([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
  self.navigationController.interactivePopGestureRecognizer.enabled = YES;
  }
  }
