Resizing UITextView - Height not adjusting

This should be so easy, but for some reason it's not working for me. I want to resize my text box and ideally have some padding at the bottom. For now I'll settle for resizing properly.

The setup

A single view on my storyboard

Interface

@property (weak, nonatomic) IBOutlet UITextView *messageTextBox;

Implementation

- (void)viewDidLoad
{
    [super viewDidLoad];
    _messageTextBox.text = _message.body;
    [_messageTextBox sizeToFit];  
}

I have tried several different solutions including changing the height of the frame and other user suggestions here...

This is using ios7 and xcode 5, but I don't see why there would be an issue with such a basic function.

To add to my confusion, I have logged the frame height and contentsize after sizeToFit. My results are:

2013-10-02 18:40:20.803 narg[21467:a0b] H of the frame: 618.000000
2013-10-02 18:40:20.804 narg[21467:a0b] W of the frame: 469.000000
2013-10-02 18:40:20.804 narg[21467:a0b] Reported H of contentSize property on object 42.000000

So the frame clearly knows the correct height, but on the display all the text is cutoff and the box doesn't adjust size.

Solution

Here was the answer to my issue. At some point I had checked off Autolayout on my view. This effectively locked the view and didn't allow me to adjust the frame size.

If you are seeing a similar issue that the frame is not resizing try the following:

Go to interface builder and open the view
Click on the file inspector
Deselect auto-layout.

This resolved my issue.
