viewcontroller konform zum Protokoll "UITableViewDataSource, Video Mode Delegate"?

Question

import UIKit 
import Alamofire 

protocol VideoModelDelegate{ 
func dataReady() 
} 

class VideoModel: NSObject { 

let API_KEY = "" 
let UPLOADS_PLAYLIST_ID = "" 


var videoArray = [Video]() 

var delegate:VideoModelDelegate? 

func getFeedVideos() -> [Video] { 

     Alamofire.request(.GET, "",parameters: ["part":"snippet",   "playlistId":UPLOADS_PLAYLIST_ID ,"key":API_KEY], 
encoding: ParameterEncoding.URL, headers: nil).responseJSON {(response) -> Void in 

     if let JSON = response.result.value{ 

      var arrayOfVideos = [Video]() 

      for video in JSON["items"] as! NSArray { 
       print(video) 
       let videoObj = Video() 
     videoObj.videoId = video.valueForKeyPath("snippet,resourceId,  videoId") 
       String 
     videoObj.videoTitle = video.valueForKeyPath("snippet.title") as! String 
     videoObj.videoDescription = video.valueForKeyPath("snippet.description") as! 
       String 
       videoObj.videoThumbnailUrl = video.valueForKeyPath("snippet.thumbnails.maxres.url") as! String 
       arrayOfVideos.append(videoObj) 
     } 

      self.videoArray = arrayOfVideos 

      if self.delegate != nil { 
       self.delegate!.dataReady() 

      } 

     } 
    } 
     } 
    func getVideos() -> [Video] { 
    var videos = [Video]() 

    let video1 = Video() 

    video1.videoId = "" 
    video1.videoTitle = "" 

    videos.append(video1) 

    return videos 

} 

}

[Zusätzliche Fehler] [Fehler] 1 Wie meine Viewcontroller zu Protokoll "UITableViewDataSource und Videomodus Delegate" entsprechen machen?

Ich habe eine Reihe von vorgeschlagenen Änderungen in den vorherigen Threads versucht, aber nichts hat mich durch, bitte helfen Sie mir aus.

Vielen Dank im Voraus

Es sieht aus, als ob Sie nicht die Methode didReceivedMemoryWarning geschlossen haben: und die Tableview Delegatmethoden sind dann effektiv innerhalb dieser Methode das Problem verursacht. Fügen Sie eine schließende Klammer hinzu und es sollte in Ordnung sein:

Update: Hier ist der aktualisierte Code. Es gab einige weitere Formatierungsprobleme mit Klammern und ein Fehler mit dem if-Anweisung in der cellForRowAtIndex:
