How to zoom on an UITextView inside a UIScrollView?

Question

I have a UIScrollView which contains instances of an UIView subclass.

This UIView has a CAShapeLayer as a sublayer of its layer, and a UITextView as a subview.

With zooming enabled on the UIScrollView , the CAShapeLayer remains sharp when I zoom, but the UITextView doesn't.

Is there a way to have the UITextView redraw at the correct resolution?

Answer 1

you can use [yourTextView contentScaleFactor] or [yourTextView.layer contentsScale] . Set it to the current scalefactor.
