Anoop's answer works like a charm. You can also do this in IB using User Defined Runtime Attributes:
- choose Button in IB
- Add Attribute
- KeyPath: titleLabel.adjustsFontSizeToFitWidth
- Type: Boolean
- Value: true
Screenshot from IB
Set Minimumfontsize is not available in iOS8 use minimumscalefactor instead.
