segueが動作しないための準備の複数の条件

Question

私は、View Controller間でデータを送信するためにsegueの準備を使用しています。識別子が "ShowPost"の場合は最初の条件が働き、View ControllerにURLを送信します。しかし、識別子が "profileInfo"の場合、segueはデータを送信しません。

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if segue.identifier == "ShowPost" { 
    if let indexPath = tableView.indexPathForSelectedRow { 
     let _url = searchResults[indexPath.row]["link"].stringValue 
     let destinationController = segue.destinationViewController as! ShowPostViewController 
     destinationController.url = _url 
    } 
    else if segue.identifier == "ProfileInfo" { 
     if let indexPath = tableView.indexPathForSelectedRow { 
     let _userName = searchResults[indexPath.row]["owner"]["display_name"].stringValue 
     // print("name dc: \(destinationController.userName)") 
     let _userId = searchResults[indexPath.row]["owner"]["user_id"].stringValue 
     let _userReputation = searchResults[indexPath.row]["owner"]["reputation"].stringValue 
     let _ppImageString = searchResults[indexPath.row]["owner"]["profile_image"].stringValue 
     let destinationController = segue.destinationViewController as! ProfileInfoViewController 
     destinationController.userName = _userName 
     destinationController.userId = _userId 
     destinationController.userReputation = _userReputation 
     destinationController.ppImageString = _ppImageString 
     } 
    } 
    } 
} 

Answer 1

else文は最初のif文の内側に追加され、実行することはできません。

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if segue.identifier == "ShowPost" { 
     if let indexPath = tableView.indexPathForSelectedRow { 
      let _url = searchResults[indexPath.row]["link"].stringValue 
      let destinationController = segue.destinationViewController as! ShowPostViewController 
      destinationController.url = _url 
     } 


    } 
    else if segue.identifier == "ProfileInfo" { 

      if let indexPath = tableView.indexPathForSelectedRow { 

       let _userName = searchResults[indexPath.row]["owner"]["display_name"].stringValue 
       // print("name dc: \(destinationController.userName)") 
       let _userId = searchResults[indexPath.row]["owner"]["user_id"].stringValue 
       let _userReputation = searchResults[indexPath.row]["owner"]["reputation"].stringValue 
       let _ppImageString = searchResults[indexPath.row]["owner"]["profile_image"].stringValue 
       let destinationController = segue.destinationViewController as! ProfileInfoViewController 
       destinationController.userName = _userName 
       destinationController.userId = _userId 
       destinationController.userReputation = _userReputation 
       destinationController.ppImageString = _ppImageString 


      } 
     } 

} 

Answer 2

それが実行されることはありませんので、あなたelse文は、if文の内側です。

したがって、別のif文を別に入力してください。

インターフェイスビルダーから適切な識別子とクラスを設定していることを確認してください。

多分それがスイッチと少し明確に次のようになります。

switch segue.identifier ?? "" { 
    case "ShowPost": 
     if let indexPath = tableView.indexPathForSelectedRow { 
      let _url = searchResults[indexPath.row]["link"].stringValue 
      let destinationController = segue.destinationViewController as! ShowPostViewController 
      destinationController.url = _url 
     } 
    case "ProfileInfo": 
     if let indexPath = tableView.indexPathForSelectedRow { 

      let _userName = searchResults[indexPath.row]["owner"]["display_name"].stringValue 
      // print("name dc: \(destinationController.userName)") 
      let _userId = searchResults[indexPath.row]["owner"]["user_id"].stringValue 
      let _userReputation = searchResults[indexPath.row]["owner"]["reputation"].stringValue 
      let _ppImageString = searchResults[indexPath.row]["owner"]["profile_image"].stringValue 
      let destinationController = segue.destinationViewController as! ProfileInfoViewController 
      destinationController.userName = _userName 
      destinationController.userId = _userId 
      destinationController.userReputation = _userReputation 
      destinationController.ppImageString = _ppImageString 
    } 
    default: break 
}

       } 
      } 

    }
