Line Breaks and Number of Lines in Swift Label (Programmatically)

Question

By selecting a Label in a StoryBoard, I can select Line Break to be Word Wrap and change number of lines to be more than 1. How can I do that Programma

Answer 1

Note with Swift 3 you need to use updated method byWordWrapping

productNameLabel.lineBreakMode = .byWordWrapping
productNameLabel.numberOfLines = 1

---

Or for adding Ellipsis at the end use byTruncatingTail

productNameLabel.lineBreakMode = .byTruncatingTail
productNameLabel.numberOfLines = 1

Answer 2

You can do this to set it programmatically

 label.lineBreakMode = NSLineBreakMode.ByWordWrapping
 label.numberOfLines = 3

Swift 3/4

label.lineBreakMode = .byWordWrapping
label.numberOfLines = 3

Answer 3

If you want the label to have multiple lines, do this:

var myLabel:UILabel = UILabel(frame: CGRectMake(7, 200, 370, 100))
myLabel.lineBreakMode = NSLineBreakMode.ByWordWrapping
myLabel.numberOfLines = 0                      //'0' means infinite number of lines

Do remember to increase the height in "CGRectMake(7, 200, 370, 100)"         <-- This
Otherwise the label won't be able to take the multiple lines of text.
