How do I sizeToFit a UILabel by changing only the height and not the width?

Question

``` [self.Review sizeToFit]; ``` Result before sizeToFit: ``` NSStringFromCGRect(self.Review.frame): {{90, 20}, {198, 63}} ``` Result After sizeToFit: ``` NSStringFromCGRect(self.Review.frame): {{90, 20}, {181, 45}} ``` I want the width to remain the same. I just want to change the height. THe automask is ``` (lldb) po self.Review (UILabel *) $1 = 0x08bb0fe0 > ``` I know that there is a way to do so with: How to adjust and make the width of a UILabel to fit the text size? The answers are either strange (we need to resupply the font information). Or unclear. You will also need to define a maximum width, and tell your program what to do if sizeToFit gives you a width greater than that maximum. I will use the strange solution of using `sizeWithFont`. It's strange because UILabel already knows…

Accepted Answer

This is how it is done. Because the label already contains the font information, including it in this method call is trivial.

```
CGSize size = [label.text sizeWithFont:label.font
                     constrainedToSize:CGSizeMake(maxWidth, MAXFLOAT)
                         lineBreakMode:UILineBreakModeWordWrap]; 
CGRect labelFrame = label.frame;
labelFrame.size.height = size.height;
label.frame = labelFrame;
```

Swift version using the more up-to-date `boundingRectWithSize`:

```
let maxHeight = CGFloat.infinity
let rect = label.attributedText?.boundingRectWithSize(CGSizeMake(maxWidth, maxHeight), 
       options: .UsesLineFragmentOrigin, context: nil)
var frame = label.frame
frame.size.height = rect.size.height
label.frame = frame
```
