Question

I am trying to hide the navigational bars according to the cursor positions.so, that I can use the full screen of the iPhone. But I donno how to start it.

Similar (less confusing 🙂 ) question: Show/hide UIToolbar, "match finger movement", precisely as in for example iOS7 Safari

Answer 1

Use the below code if you want to hide and unhide the navigation bar on double tap on any part of the view

In your .h file:

IBOutlet UINavigationController *navigationController;

Connect the IBOutlet in your XIB.

in your .m file:

  -(void)viewDidLoad {

  [super viewDidLoad];

  [navigationController setNavigationBarHidden:YES];



 }

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [touches anyObject];

  if (touch.tapCount == 2) {

       [navigationController setNavigationBarHidden:NO];
       [NSTimer scheduledTimerWithTimeInterval:(1.0) target:self   selector:@selector(hideBar) userInfo:nil repeats:NO];


      }

  }

-(void)hidebar{

[navigationController setNavigationBarHidden:YES];



}

Do the modifications as per your requirement.

Happy coding!
