How to programmatically change the font of a tag?

Question

Is it possible to change the font of the tag programmatically after I installed it in the storyboard of my WatchKit extension?

Answer 1

You can do this via setAttributedText on a WKInterfaceLabel . Use NSFontAttributeName for the key when you set the font in an attribute text dictionary.

Answer 2

 import WatchKit import Foundation class InterfaceController: WKInterfaceController { @IBOutlet weak var label1: WKInterfaceLabel! @IBOutlet weak var label2: WKInterfaceLabel! @IBOutlet weak var label3: WKInterfaceLabel! override func awakeWithContext(context: AnyObject?) { super.awakeWithContext(context) // Configure interface objects here. let headlineFont = UIFont.preferredFontForTextStyle(UIFontTextStyleHeadline) let footnoteFont = UIFont.preferredFontForTextStyle(UIFontTextStyleFootnote) let text1 = NSMutableAttributedString(string: "Tangerine Bold") text1.addAttribute(NSFontAttributeName, value: headlineFont, range: NSMakeRange(0, 3)) text1.addAttribute(NSFontAttributeName, value: footnoteFont, range: NSMakeRange(3, 3)) label1.setAttributedText(text1) let regularFont = UIFont.systemFontOfSize(24) let heavyFont = UIFont.systemFontOfSize(24, weight: UIFontWeightHeavy) let text2 = NSMutableAttributedString(string: "Tangerine Regular") text2.addAttribute(NSFontAttributeName, value: regularFont, range: NSMakeRange(0, 3)) text2.addAttribute(NSFontAttributeName, value: heavyFont, range: NSMakeRange(3, 3)) label2.setAttributedText(text2) let text3 = NSMutableAttributedString(string: "Tangerine Bold (Code)") if let tangerineBoldFont = UIFont(name: "Tangerine-Bold", size: 20) { text3.addAttribute(NSFontAttributeName, value: tangerineBoldFont, range: NSMakeRange(0, 21)) } label3.setAttributedText(text3) } override func willActivate() { // This method is called when watch view controller is about to be visible to user super.willActivate() } override func didDeactivate() { // This method is called when watch view controller is no longer visible super.didDeactivate() } }
