MGLAttributedExpression
@interface MGLAttributedExpression : NSObject
An MGLAttributedExpression
object associates text formatting attibutes (such as font size or
font names) to an NSExpression
.
Example
let redColor = UIColor.red
let expression = NSExpression(forConstantValue: "Foo")
let attributes: [MGLAttributedExpressionKey: NSExpression] = [.fontNamesAttribute : NSExpression(forConstantValue: ["DIN Offc Pro Italic",
"Arial Unicode MS Regular"]),
.fontScaleAttribute: NSExpression(forConstantValue: 1.2),
.fontColorAttribute: NSExpression(forConstantValue: redColor)]
let attributedExpression = MGLAttributedExpression(expression, attributes:attributes)
