Scaling UITextView using contentScaleFactor property

Question

I am trying to create a higher resolution image of a UIView, specifically UITextView.

This question and answer is exactly what I am trying

Answer 1

Be sure to apply the contentScaleFactor to all subviews of the UITextView. I've just tested the following with a UITextView and found it to work:

- (void)applyScale:(CGFloat)scale toView:(UIView *)view {
    view.contentScaleFactor = scale;
    view.layer.contentsScale = scale;
    for (UIView *subview in view.subviews) {
        [self applyScale:scale toView:subview];
    }
}
