UIButton with two lines of text in the title (numberOfLines=2)

You don’t need to add a UILabel to the UIButton. That’s just extra objects and work.

Set these properties on the titleLabel of your button.

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
button.titleLabel.numberOfLines = 2;//if you want unlimited number of lines put 0

Swift:

button.titleLabel!.lineBreakMode = NSLineBreakMode.ByWordWrapping
button.titleLabel!.numberOfLines = 2//if you want unlimited number of lines put 0
