Adjust width of UILabel based on its contents

I had a look on SO before asking this question. All the questions are about adjusting the height of a UILabel and not its width. I tried alternative methods but it did not work such as [label sizeToFit];. Is it possible to adjust the width of a label based on its text? I create my label in a UITableViewCell in story board. I want to be able to adjust its width based on the text that it is assigned. I dont want to resize the font size.

I set the text of the label in CellForRowAtIndexPath.

Examples would be great please.

Thanks in advance :)

Update 1: I have a custom cell that I am making in Storyboard so not programmatically. I set the contents of each cell in CellForRowAtIndexPath, for example, myLabel.text = recipe.name. The name label is quite small, however I would like to extend its width based on the length of the text, not truncate the tail or shrink the size of the text.

Update2: I have a lot of other UIElements in the cell. So I have a label in the top left, top right, bottom left, bottom right, and a picture in the middle, there default is 120 because they have a background color. I set it small the there is not a huge amount of empty space in the label.

Get the size of the string: 

  //Replace FLT_MAX with the maximum height/width you want the label to be, if no maximum leave as FLT_MAX.
CGSize stringSize = [YOUR_STRING sizeWithFont:YOUR_FONT constrainedToSize:CGSizeMake(FLT_MAX, FLT_MAX) lineBreakMode:NSLineBreakByWordWrapping];

Then size your label: 

[YOUR_LABEL setFrame:CGRectMake(0, 0, stringSize.width, stringSize.height)];

In iOS 7 sizeWithFont is deprecated, use boundingRectWithSize instead:

NSDictionary *stringAttributes = [NSDictionary dictionaryWithObject:YOUR_LABELS_FONT
                                                                 forKey: NSFontAttributeName];

CGSize stringSize = [text boundingRectWithSize:CGSizeMake(FLT_MAX, FLT_MAX)
                                             options:NSStringDrawingTruncatesLastVisibleLine |
                                                     NSStringDrawingUsesLineFragmentOrigin
                                          attributes:stringAttributes context:nil].size;

You don't need to set explicit width for UILabel. UILabel provides intrinsic content size when used with autolayout. If you add constraints that provide the label's x,y position(Top Space constraint + Leading Space constraint), autolayout will be able to determine its width height based on the content.

CGSize maxSize = CGSizeMake(250, CGFLOAT_MAX); //250 is max desired width
CGSize textSize = [Label.text sizeWithFont:Label.font constrainedToSize:maxSize];
Label.frame = CGRectMake(0, 0, textSize.width, 15); // desired Bounds

Using above code you can get frame size for perticular text, & then resize label accordingly
