size of the NSString to fit on UItextview

Question

i want to find the size of NSString to display on UITextview. It is working good for English. But if the string is other languages like spanish, hindi, japanese means it is working slow:

CGSize ContentSize=[MainContentString sizeWithFont:TextView.font constrainedToSize:CSize lineBreakMode:UILineBreakModeWordWrap];

Is there a way to do it faster?

Answer 1

There is actually a very easy way to do resizing of the UITextView to its correct height of the content. It can be done using the UITextView contentSize.

CGRect frame = _textView.frame;
frame.size.height = _textView.contentSize.height;
_textView.frame = frame;

Answer 2

Check out UIView's autoresizesSubviews and contentMode - play with them in the storyboard.

Try it both with and without your implementation - see if it works.
