탭 표시 줄을 선택하면 검은 색 화면이 나타납니다.

Question

응용 프로그램의 "친구"탭으로 전환 할 때 검정색 화면에 문제가 있습니다. 이것은 내 friendsviewcontroller 때문에 발생합니다. 내가 viewcontroller에 대한 링크를 제거하고 정상적인 화면을 보여 주었기 때문에 나는 이것을 안다. 누군가가 내가 잘못

FriendsViewController을 한 일을 볼 수 있기를 바랍니다 : ronatory에서 알 수 있듯이

import UIKit 
import FBSDKLoginKit 


class FriendsViewController: UITabBarController, UITableViewDelegate,UITableViewDataSource{ 



@IBOutlet weak var tableView: UITableView! 
@IBOutlet weak var friendTypeSwitch: UISegmentedControl! 

@IBOutlet weak var friendSearchBar: UITextField! 
var user:User = User() 

override func viewDidLoad() { 
    super.viewDidLoad() 

    print("Friends tab") 
    // Do any additional setup after loading the view. 
} 
override func viewDidAppear(_ animated: Bool) { 
    print("view did appear") 
} 






func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    return 30 
} 
//What to do with tableview 
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    let cell = self.tableView.dequeueReusableCell(withIdentifier: "friendCell", for: indexPath) as! friendsCustomCell 
    user.username = "kulgut123" 

    cell.friendName.text = user.username 



      return cell 
} 
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat { 
    return UITableViewAutomaticDimension 
} 

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat { 
    return UITableViewAutomaticDimension 
} 



} 

class friendsCustomCell: UITableViewCell{ 

@IBOutlet weak var friendImg: UIImageView! 

@IBOutlet weak var friendName: UILabel! 

} 

Answer 1

, 당신의 UIViewController 대신 UITabBarController가에서 FriendsViewController를 서브 클래스해야한다.

class FriendsViewController: UIViewController, UITableViewDelegate,UITableViewDataSource { 
     //type your code here 
}
