Excessive hidden display in navigationBar

I believe I must have encountered in use, one page hides navigationBar, the other does not hide. When two pages push and pop, especially when there is a side slip gesture to return, no processing will cause the sliding back, the navigationBar position is empty, directly display a black or show the next layer of view, very ugly. This requires us to add excessive animation to hide or show navigationBar:

After the return, the page that will appear implements the viewWillAppear method. Set it to YES if you need to hide it, and set it to NO if you need to display it.

-(void) viewWillAppear: (BOOL) animated {[super viewWillAppear:animated]; [self.navigationController setNavigationBarHidden:NO animated:YES];} Thank you for reading!
