Swift 3 - alert style

Question

我在我的項目中有alert。 alert就像其他警報一樣簡單。我想改變font style and color。這怎麼可能？

在此先感謝！

Answer 1

let attributedString = NSAttributedString(string: "YourTitle", attributes: [ 
    NSFontAttributeName : UIFont.systemFontOfSize(18), //your font here 
    NSForegroundColorAttributeName : UIColor.black() 
]) 
let alert = UIAlertController(title: "TextTitle", message: "YourMessage", preferredStyle: .Alert) 

alert.setValue(attributedString, forKey: "attributedTitle") 
let cancelAction = UIAlertAction(title: "Cancel", 
style: .Default) { (action: UIAlertAction!) -> Void in 
} 

presentViewController(alert, 
animated: true, 
completion: nil) 

Answer 2

可以使用SweetAlert

SweetAlert().showAlert("Here's a message!", subTitle: "It's pretty, isn't it?", style: AlertStyle.None)
