title: measure the amout of adjustsFontSizeToFitWidth for a UILabel or textField
body: <p>UILabels and textFields can auto scale their fonts to fit the space of the view (as text accumulates for instance). Is there a way to measure the amount of the scale performed? As it seems, when auto scaling, the value of myLabel.font.pointsize or myTextField.font.pointSize remains the same regardless of the displayed scale of the text.</p>
