Swift Comment changer la couleur du titre de UIAlertController

let atsortingbutedSsortingng = NSAtsortingbutedSsortingng(ssortingng: "Title", atsortingbutes: [ NSFontAtsortingbuteName : UIFont.systemFontOfSize(15), //your font here NSForegroundColorAtsortingbuteName : UIColor.redColor() ]) let alert = UIAlertController(title: "", message: "", preferredStyle: .Alert) alert.setValue(atsortingbutedSsortingng, forKey: "atsortingbutedTitle") let cancelAction = UIAlertAction(title: "Cancel", style: .Default) { (action: UIAlertAction!) -> Void in } presentViewController(alert, animated: true, completion: nil) 

J'ai ajouté la bonne ligne de code à ma réponse car elle est beaucoup plus concise que la réponse ci-dessous.

Ce que push25 dit est correct, seulement vous devez utiliser le encoding à key-valeur afin de définir la string atsortingbuée. (Merci dupuis2387 )

  //Define a color let color = UIColor.redColor() //Make a controller let alertVC = UIAlertController(title: "Dont care what goes here, since we're about to change below", message: "", preferredStyle: UIAlertControllerStyle.Alert) //Title Ssortingng var hogan = NSMutableAtsortingbutedSsortingng(ssortingng: "Presenting the great... Hulk Hogan!") //Make the atsortingbutes, like size and color hogan.addAtsortingbute(NSFontAtsortingbuteName, value: UIFont.systemFontOfSize(40.0), range: NSMakeRange(24, 11)) hogan.addAtsortingbute(NSForegroundColorAtsortingbuteName, value: color, range: NSMakeRange(0, NSSsortingng(ssortingng: hogan.ssortingng).length)) //Set the new title //Use "atsortingbutedMessage" for the message alertVC.setValue(hogan, forKey: "atsortingbutedTitle") //This will change the button color alertVC.view.tintColor = UIColor.orangeColor() //Make the button let button:UIAlertAction = UIAlertAction(title: "Label text", style: UIAlertActionStyle.Default, handler: { (e:UIAlertAction!) -> Void in println("\(e)") }) //You can add images to the button let accessoryImage:UIImage = UIImage(named: "someImage")! button.setValue(accessoryImage, forKey:"image") //Add the button to the alert alertVC.addAction(button) //Finally present it self.presentViewController(alertVC, animated: true, completion: nil) 

 Alert(self, Title: “Hello”, TitleColor: UIColor.whiteColor(), Message: “World”, MessageColor: UIColor.whiteColor(), BackgroundColor: UIColor.blackColor(), BorderColor: UIColor.yellowColor(), ButtonColor: UIColor.yellowColor()) func Alert(View: ViewController, Title: Ssortingng, TitleColor: UIColor, Message: Ssortingng, MessageColor: UIColor, BackgroundColor: UIColor, BorderColor: UIColor, ButtonColor: UIColor) { let TitleSsortingng = NSAtsortingbutedSsortingng(ssortingng: Title, atsortingbutes: [NSFontAtsortingbuteName : UIFont.systemFontOfSize(15), NSForegroundColorAtsortingbuteName : TitleColor]) let MessageSsortingng = NSAtsortingbutedSsortingng(ssortingng: Message, atsortingbutes: [NSFontAtsortingbuteName : UIFont.systemFontOfSize(15), NSForegroundColorAtsortingbuteName : MessageColor]) let alertController = UIAlertController(title: Title, message: Message, preferredStyle: .Alert) alertController.setValue(TitleSsortingng, forKey: "atsortingbutedTitle") alertController.setValue(MessageSsortingng, forKey: "atsortingbutedMessage") let okAction = UIAlertAction(title: "OK", style: .Default) { (action) in } let cancelAction = UIAlertAction(title: "Cancel", style: .Default, handler: nil) alertController.addAction(okAction) alertController.addAction(cancelAction) let subview = alertController.view.subviews.first! as UIView let alertContentView = subview.subviews.first! as UIView alertContentView.backgroundColor = BackgroundColor alertContentView.layer.cornerRadius = 10 alertContentView.alpha = 1 alertContentView.layer.borderWidth = 1 alertContentView.layer.borderColor = BorderColor.CGColor //alertContentView.tintColor = UIColor.whiteColor() alertController.view.tintColor = ButtonColor View.presentViewController(alertController, animated: true) { // ... } } 

Vous pouvez également append un UIAlertAction avec le titre "" (espace) et append un UILabel personnalisé à UIAlertController.view à l'endroit du titre.
