Resizing UITextView - Height not adjusting

Question

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.

Answer 1

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.

Have a look here to calculate the good frame of the UITextView depending of your text _message.body. You can add a gap to have a bottom padding like this :

- (CGFloat)textViewHeightForAttributedText:(NSAttributedString*)text andWidth:(CGFloat)width
{
    UITextView *calculationView = [[UITextView alloc] init];
    [calculationView setAttributedText:text];
    CGSize size = [calculationView sizeThatFits:CGSizeMake(width, FLT_MAX)];
    return size.height + 50; // 5O is your gap for example
}
