Autoshrink on a UILabel with multiple lines

Question

Is it possible to use the autoshrink property in conjunction on multiple lines on a UILabel? for example, the large text size possible on 2 available lines.

Answer 1

There is a method on NSString, -sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode: which has apparently existed since iOS 2.0, but unfortunately is deprecated in iOS 7 without a suggested alternative as the automatic reduction of font size is discouraged. I don't really understand Apple's stance on this as they use it in keynote etc and I think if the font sizes are within a small range it is ok. Here's an implementation in Swift using this method.

var newFontSize: CGFloat = 30
    let font = UIFont.systemFontOfSize(newFontSize)
    (self.label.text as NSString).sizeWithFont(font, minFontSize: 20, actualFontSize: &newFontSize, forWidth: self.label.frame.size.width, lineBreakMode: NSLineBreakMode.ByWordWrapping)
    self.label.font = font.fontWithSize(newFontSize)

I'm not aware of a way this can be achieved without using deprecated methods.
