Could anyone help me out or give me some advise. Thanks

Answer 1

If you need to know the CGSize that is taken by your NSString if rendered on a single line, use CGSize sz = [textView.text sizeWithFont:_textView.font] then adjust your frame given this size value.

If you need to know the size taken by your text if rendered on multiple lines, wrapping it if the text reaches a given width, use sizeWithFont:constrainedToSize:lineBreakMode: instead, etc.

Answer 2

I had the same problem some time ago (but with the height of the UITextView ) and I created a CGRect with a size that would fit the contentSize of the UITextView , Try the code below

// assuming that you have a UITextView named textView with some text on it
CGRect textFrame = self.textView.frame;
textFrame.size.width = self.textView.contentSize.width;
self.textView.frame = textFrame;

Answer 3

try this one it worked for me

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

happy coding....
