IOS填充Twitter發佈

Question

我正在尋找關於如何填充文本到Twitter發佈一點點幫助，使用下面的按鈕，我可以得到一個標籤，以顯示

當「爲00:35' 的目標」點擊按鈕我想打開我可以製作出來的twitter，然後填充它以準備發送推文。

@IBAction func goalClicked(_ sender: UIButton) { 

     tempTimelineLbl.text = "\(stopWatchString)' \("Goal for")" 
} 

我會用下面的代碼打開Twitter的

let twUrl: URL = URL(string: "twitter://user?screen_name=\(club.twitter)")! 
      let twUrlWeb: URL = URL(string: "https://twitter.com/\(club.twitter)")! 

      if (UIApplication.shared.canOpenURL(twUrl)) { 
       UIApplication.shared.open(twUrl, options: [:], completionHandler: { 
        (Sucess) in 
       }) 
      } else { 
       UIApplication.shared.open(twUrlWeb, options: [:], completionHandler: { 
        (Sucess) in 
       }) 
    }

@IBAction func goalClicked(_ sender: UIButton) { 

     let stopWatchString = stopWatch.elapsedTimeSinceStart() 
     stopwatchLabel.text = stopWatchString 

     let vc = SLComposeViewController(forServiceType: SLServiceTypeTwitter) 
     vc?.setInitialText("Some Test String") 
     vc?.add(#imageLiteral(resourceName: "goal")) 
     present(vc!, animated: true, completion: nil) 

    }
