How can I highlight the BarButton in navigation bar without tapping it?

Question

Typically, the UIBarButtonItem will be highlighted when we tap it.

However, I intend to show the users that the action is automatically done for them when the view is loaded after 4 sec.

So I want to highlight the Button without tapping it.

How can I achieve that?

For a UIVIew object such as a UIButton , you can either use the following code Glow category on UIView that adds support for making views glow or use this example .

If you are using the first one, you can just call startGlowing and stopGlowing . When you call startGlowing , the view will start to pulse with a soft light, this effect is removed when stopGlowing is called. Check this .

For UIBarButtonItem , you might have to use the solution provided here .
