如何在Swift 3中调整字体大小以适合高度（而非宽度）

Question

label.minimumScaleFactor works very well to fit the font to the width.

However the font size, for alphabet such as "I", is typically larger than other letters such as "H". This makes the design very weird.

I need help to fit the font to the label height. Any solutions/functions/class that I can adopt?

Answer 1

Swift 3...

label.minimumScaleFactor = 0.1    //you need
label.adjustsFontSizeToFitWidth = true    
label.lineBreakMode = .byClipping
label.numberOfLines = 0
