Updated code for Swift 3.0:

yourButton.titleLabel?.minimumScaleFactor = 0.5
yourButton.titleLabel?.numberOfLines = 0
yourButton.titleLabel?.adjustsFontSizeToFitWidth = true

Answer 2

self.mybutton.titleLabel.minimumScaleFactor = 0.5f;
self.mybutton.titleLabel.numberOfLines = 0;   <-- Or to desired number of lines
self.mybutton.titleLabel.adjustsFontSizeToFitWidth = YES;

... did the trick, after layoutIfNeeded in viewDidLoad As it turns out, all those must be set to actually adjust the font-size, not just making it fit into the frame.

Update for Swift 3:

mybutton.titleLabel?.minimumScaleFactor = 0.5
mybutton.titleLabel?.numberOfLines = 0   <-- Or to desired number of lines
mybutton.titleLabel?.adjustsFontSizeToFitWidth = true

Answer 3

If you prefer do in storyboard, just click the button, then show attributes inspector, and set the line break to "Word Wrap".

Write this line after your code:

yourButton.SizeToFitWidth=YES;

try this:

  [myButton setFont:[[myButton font] fontWithSize:--originalButtonFontSize]];
  textWidth = [text sizeWithFont:[myButton font]].width;

}

Answer 6

to make text horizontally and vertically fit with button bounds :

1 - set button alignment like image (* VERY IMPORTANT *)

2 - add this lines of code in your ViewController

btnTest.setTitle("Test for multi line in button show line in button show Test for multi line in button show line in button show", for: .normal)
btnTest.titleLabel!.textAlignment = .center
btnTest.titleLabel!.numberOfLines = 0
btnTest.titleLabel!.adjustsFontSizeToFitWidth = true
btnTest.titleLabel!.minimumScaleFactor = 0.5
// below line to add some inset for text to look better
// you can delete or change that
btnTest.contentEdgeInsets = UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)

• note that DON'T using btnTest.titleLabel!.lineBreakMode = NSLineBreakMode.byWordWrapping or other BreakMode in your code . for enable multiline in button . just using from above code

final result :
