有時候我們在指定頁面不需要右滑動手勢返回頁面，那麼在指定頁面新增一下程式碼，就能實現該功能

**-

• (void)viewDidAppear:(BOOL)animated {
  [super viewDidAppear:YES];
  // 禁用iOS7返回手勢
  self.navigationController.interactivePopGestureRecognizer.enabled = NO; }
  -(void)viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:YES];
  // 開啟
  self.navigationController.interactivePopGestureRecognizer.enabled = YES; }
