UITextView scrollEnabled = YES not working after set scrollEnabled = NO in iOS8

Question

I create a demo for checking UITextView scrollEnabled. It only contains 1 UITextView and 2 button enable and disable scroll

• I test on

Answer 1

The problem is that in iOS 8, contentSize is not adjusted correctly when scrollEnabled is changed. A small adjustment to your enableScrollButtonPressed method will successfully work around the problem.

-(IBAction)enableScrollButtonPressed:(id)sender
{
    self.myTextView.scrollEnabled = YES;
    self.myTextView.contentSize = [self.myTextView sizeThatFits:self.myTextView.frame.size];
}
