How to blink a touch area in UILabel iPhone?

I have an UILabel. I want to glow the touch area in it. That is, when I click on a point in that UILabel, a small circular portion around the touch point should be presented with glowing effect. How can get this?

Solution

  • Well you can do that by creating a CALayer or a CAGradientLayer based on how you want your glow and add it as a sublayer to the label's layer at the location of the touch.

    For enabling the touch on UILabel, look at userInteractionEnabled property. You will need to set it to YES.

    Then you will need to attach a UITapGestureRecognizer to the label for getting the tap. Once you have the touch location, add the custom glow layer as a subview to the label's layer in an invisible state. Animate the glow layer in and out. You might want to repeat a few times before removing the glow layer as a sublayer at completion.
