@interface ViewController ()  
    {  
        BOOL isflage;  
    }  
    @end  
      
    @implementation ViewController  
      
    - (void)viewDidLoad  
    {  
        [super viewDidLoad];  
        // Do any additional setup after loading the view from its nib.  
        isflage = YES;  
        [self.navigationController setNavigationBarHidden:isflage animated:YES];  
      
    }  
      
    #pragma mark onClick  
      
    -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event  
    {  
        isflage = !isflage;  
        [self.navigationController setNavigationBarHidden:isflage animated:YES];  
    }  
      
    @end

上述代码的实现结果就是：



先隐藏navigationController，之后点击会显示，再点击又会隐藏，超简单吧。



同样tabBarController也是同样的实现结果。
