IOS-hide Navigation:

A third-party class library is used. For the Navigation of the slide side, if you want to hide one of the viewcontrollers in a view of the project, no good method is found because you cannot find the Navigation when the third-party class loads. finally, this method is used to call hide before the view is loaded.

-(Void) viewWillAppear :( BOOL) animated {[super viewWillAppear: animated]; [self. navigationController setNavigationBarHidden: YES animated: animated];}

After hiding it, The ViewController that is pushed out will not have Navigation. Change YES to NO in the method above.

-(Void) viewWillAppear :( BOOL) animated {[super viewWillAppear: animated]; [self. navigationController setNavigationBarHidden: NO animated: animated];}

Record, extend, and handle other events before loading the view.
