The height of textView will never grow with its contentSize in Xcode 5 & iOS 7

Question

The height of textView will never grow with its contentSize in Xcode 5 & iOS 7.

Answer 1

I think you are presenting popOverView using

[popOverView presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:NO];

Please change ArrowDirections from UIPopoverArrowDirectionUp to UIPopoverArrowDirectionAny

Answer 2

Before X Code 5, to get the contents height of text view we use text view's property contentSize. But its no longer work with new iOS 7.

With iOS 7, we have a different property named textContainer. It gives text container of text view.

Option 1:

You need to replace the following line of code (These line of code set the text view frame according to its content length.)

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

with

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

_textView.textContainer.size gives the same value which was given by _textView.contentSize earlier.

Option 2:

We can also replace the line of code

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

with

CGRect frame = _textView.frame;
 frame.size.height = [_textView sizeThatFits:CGSizeMake(txtView.frame.size.width, MAXFLOAT)].height;
 _textView.frame = frame;

Above lines of code will work with each iOS.
