當使用JSQMessagesViewController UI不會出現

我想實現JSQMessagesViewController，並且我遵循Ray Wenderlich教程（https://www.raywenderlich.com/122148/firebase-tutorial-real-time-chat），但UI沒有出現在我的視圖控制器上，它只是空白。這是我的pod文件。當使用JSQMessagesViewController UI不會出現

source 'https://github.com/CocoaPods/Specs.git' 
use_frameworks! 
target "Sell Goods" do 
    pod 'Firebase' 
    pod 'Firebase/Storage' 
    pod 'Firebase/Database' 
    pod 'Google/SignIn' 
    pod 'JSQMessagesViewController' 
end

我已經嘗試使用橋頭，但沒有奏效，我一步一步跟着教程。

Segue公司以ChatViewController

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    guard let editingVC = segue.destinationViewController as? ChatsViewController 
     else { 
      preconditionFailure("Bad") 
     } 
    editingVC.senderId = userID 
    editingVC.senderDisplayName = userName 
}

ChatViewController

import Firebase 
import JSQMessagesViewController 

class ChatsViewController: JSQMessagesViewController { 
var messages = [JSQMessage]() 
var outgoingBubbleImageView: JSQMessagesBubbleImage! 
var incomingBubbleImageView: JSQMessagesBubbleImage! 
override func viewDidLoad() { 
    title = "ChatChat" 
    setupBubbles() 
    //collectionView!.collectionViewLayout.incomingAvatarViewSize = CGSizeZero 
    //collectionView!.collectionViewLayout.outgoingAvatarViewSize = CGSizeZero 

    // Do any additional setup after loading the view. 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 

override func viewDidAppear(animated: Bool) { 
    resetScreen = true 
} 
private func setupBubbles() { 
    let factory = JSQMessagesBubbleImageFactory() 
    outgoingBubbleImageView = factory.outgoingMessagesBubbleImageWithColor(
     UIColor.jsq_messageBubbleBlueColor()) 
    incomingBubbleImageView = factory.incomingMessagesBubbleImageWithColor(
     UIColor.jsq_messageBubbleLightGrayColor()) 
} 
override func collectionView(collectionView: JSQMessagesCollectionView!, 
          messageBubbleImageDataForItemAtIndexPath indexPath: NSIndexPath!) -> JSQMessageBubbleImageDataSource! { 
    let message = messages[indexPath.item] 
    if message.senderId == senderId { 
     return outgoingBubbleImageView 
    } else { 
     return incomingBubbleImageView 
    } 
} 

override func collectionView(collectionView: JSQMessagesCollectionView!, 
          messageDataForItemAtIndexPath indexPath: NSIndexPath!) -> JSQMessageData! { 
    return messages[indexPath.item] 
} 

override func collectionView(collectionView: UICollectionView, 
          numberOfItemsInSection section: Int) -> Int { 
    return messages.count 
} 
override func collectionView(collectionView: JSQMessagesCollectionView!, 
          avatarImageDataForItemAtIndexPath indexPath: NSIndexPath!) -> JSQMessageAvatarImageDataSource! { 
    return nil 
} 

}

我們不能猜測是什麼只向我們展示您的POD文件回事。我們需要更多信息。 – Brandon

編輯帖子。 –

你需要調用'super.viewDidLoad'和'super.viewDidAppear' – Brandon

必須調用super.viewDidLoad & super.viewDidDisappear
