iOS应用中的表情符号警报和通知 - Xcode/Swift

Question

我正在尝试在Xcode中添加一个表情符号警报,但无法弄明白,任何帮助都非常感谢!\ XF0\x9F\X98\XB3

码:

if ((self.liveStreamTitle.text?.characters.count) == 0)
        {

            let alertView = UIAlertController.init(title: "Forgot something?", message: "Video Title is empty EMOJIHERE", preferredStyle: UIAlertControllerStyle.Alert)
            alertView.addAction(UIAlertAction.init(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
            self.presentViewController(alertView, animated: true, completion: { 

            })

            return;

        }

实际上你可以直接添加它们.

@IBAction func pressed(sender: AnyObject) {

let actionSheetController: UIAlertController = UIAlertController(title: "Are you sure?", message: "", preferredStyle: .Alert)
let cancelAction: UIAlertAction = UIAlertAction(title: " NO", style: .Cancel) { action -> Void in
                //Do your task
}
actionSheetController.addAction(cancelAction)
let nextAction: UIAlertAction = UIAlertAction(title: " YES", style: .Default) { action -> Void in
                //Do your task  
}
actionSheetController.addAction(nextAction)
self.presentViewController(actionSheetController, animated: true, completion: nil)

}

您也可以使用Unicode执行此操作

let cancelAction: UIAlertAction = UIAlertAction(title: "\u{1F425}", style: .Cancel) { action -> Void in
let nextAction: UIAlertAction = UIAlertAction(title: "\u{1F426}", style: .Default) { action -> Void in

或者这使用Unicode

let cancelAction: UIAlertAction = UIAlertAction(title: "\u{1F425} YES", style: .Cancel) { action -> Void in
let nextAction: UIAlertAction = UIAlertAction(title: "\u{1F426} NO", style: .Default) { action -> Void in
