You can use setFrame: or sizeToFit.

UPDATE:

I use sizeToFit with UILabel, and it works just fine, but UITextView is a subclass of UIScrollView, so I can understand why sizeToFit doesn't produce the desired result.

You can still calculate the text height and use setFrame, but you might want to take advantage of UITextView's scrollbars if the text is too long.

Here's how you get the text height:

#define MAX_HEIGHT 2000

NSString *foo = @"Lorem ipsum dolor sit amet.";
CGSize size = [foo sizeWithFont:[UIFont systemFontOfSize:14]
              constrainedToSize:CGSizeMake(100, MAX_HEIGHT)
                  lineBreakMode:UILineBreakModeWordWrap];

and then you can use this with your UITextView:

[textView setFont:[UIFont systemFontOfSize:14]];
[textView setFrame:CGRectMake(5, 30, 100, size.height + 10)];

[textView setFont:[UIFont systemFontOfSize:14]];
[textView setFrame:CGRectMake(5, 30, 100, size.height + 10)];

or you can do the height calculation first and avoid the setFrame line:

UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(5, 30, 100, size.height + 10)];
