使用以下方法：

 

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

退出該控制器時還原：

 

 

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

 

-- end
