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 Programmatically in Swift?

Solution 1

You can do this to set it programmatically

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

Swift 3/4

label.lineBreakMode = .byWordWrapping
label.numberOfLines = 3

Solution 2

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.

Solution 3

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

It is recommended to go with design-time setting since at times the run-time may not work as in my case.

Not much reason to set the number of lines to 1 if you want to wrap text.

I was just demonstrating how to change it.

How to do this dynamically according to text length?

Although I marked above as right answer because that is what I needed. This is recommended for auto layouts and dynamic height.

Agreed! And as much as possible, dynamic needs should be incorporated always!

[JCarlosR]

Is it necessary to create the label always programatically?
