Hide/show toolbar on tap

Because I have an wallpaper app , I want that wehen you open the app there is no toolbar and that when you tap on the screen the toolbar comes , tap again and it goes away. How to do that ?

Solution

  • You can adjust the toolbar's alpha value like so:

    To Hide:

    toolbar.alpha = 0.0;

    To Show:

     toolbar.alpha = 1.0;

    Example:

    [UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
// self.navigationController.toolbar.alpha = 0.0;
// or
// toolbar.alpha = 0.0;
[UIView commitAnimations];
