ios - 准备 segue 的多个条件不起作用

Question

我正在使用 prepare for segue 在 View Controller 之间发送数据，第一个 if 条件在标识符为“ShowPost”时起作用并将 url 发送到 View Controller 。但是当标识符是“profileInfo”时，segue 不会发送数据。

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
      }
    }
  }
}

else语句被加在第一个if语句里面，无法运行。

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


            }
        }

}
