Is it generally possible with an UITextView to have a mask which I can

  • 0

Is it generally possible with an UITextView to have a mask which I can animate at runtime? Imagine a flash light effect: You have a circle mask and then move this circle around — and only whatever is in the circle is shown of the UITextView.

Sorry to be so general, but I was only wondering if this is generally possible with an UITextView and where I would need to start to achieve such an effect. I found this: Mask UIView and this Mask text inside UITextView but neither is really about animating a mask at runtime.

Thanks!

    Yes this is completely possible and easy.

    It is very likely you *do not need the difficult concept of masks, as explained in the links you mention.

    All you have to do is make another UIView (just do it in IB), and then move that new UIView around as you see fit.

    It’s just that easy. Hope it helps.
