Question

When I’m clicking on a UIButton that located on the top of UINavigationBar I have this glossy effect:

How can I add this effect to another button that located on a UINavigatonBar but not as a left or right button item? like this:

UIButton * emptyButton = [UIButton buttonWithType:UIButtonTypeCustom];
[emptyButton setFrame:CGRectMake(119, 5, 82, 35)];
[emptyButton addTarget:self action:@selector(centerNavigationBarTitleClicked:) forControlEvents:UIControlEventTouchUpInside];
[emptyButton setBackgroundColor:[UIColor clearColor]];

[self.navigationController.navigationBar addSubview:emptyButton];

Thanks!

You simply have to set the showsTouchWhenHighlighted property to YES to get the glow effect, i.e.

emptyButton.showsTouchWhenHighlighted = YES;
