UILabel - Wordwrap text

UILabel has a property lineBreakMode that you can set as per your requirement.

If you set numberOfLines to 0 (and the label to word wrap), the label will automatically wrap and use as many of lines as needed.

If you're editing a UILabel in IB, you can enter multiple lines of text by pressing option+return to get a line break - return alone will finish editing.

In Swift you would do it like this:

    label.lineBreakMode = NSLineBreakMode.ByWordWrapping
    label.numberOfLines = 0

(Note that the way the lineBreakMode constant works is different to in ObjC)
