登錄

Question

我無法同時使用下面的環境得到了Facebook登錄組件解決後雨燕的Facebook SDK空白頁iOS的10

我已經遵循所有必要的步驟開始下載（iOS Getting Started和Swift Getting Started），即使在這裏沒有提到，如添加默認的AppDelegate方法如下步驟：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

     FacebookCore.SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: [ 
      .sourceApplication: application, 
      ]) 
     return true 

    } 

private func application(app: UIApplication, openURL url: URL, options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool { 
     return FacebookCore.SDKApplicationDelegate.shared.application(app, open: url, options: [ 
      .sourceApplication: app, 
      ]) 
    } 

@available(iOS 9.0, *) 
private func application(application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: AnyObject) -> Bool { 
    return FacebookCore.SDKApplicationDelegate.shared.application(application, open: url, sourceApplication: sourceApplication, annotation: annotation) 
} 

至於Info.plist中的內容，關於Facebook的一部分，我想我擁有所有必需的標籤，甚至有些人似乎有助於解決這種情況，在一些問題在這裏找到在SO：

<key>CFBundleURLTypes</key> 
    <array> 
     <dict> 
      <key>CFBundleURLSchemes</key> 
      <array> 
       <string>fb1619016601757957</string>

       <key>NSIncludesSubdomains</key> 
       <true/>

       <true/> 
      </dict> 
      <key>akamaihd.net</key> 
      <dict> 
       <key>NSIncludesSubdomains</key> 
       <true/> 
       <key>NSExceptionRequiresForwardSecrecy</key> 
       <true/> 
      </dict> 
     </dict> 
    </dict> 

對於最後和核心部分，超級簡化，我在登錄控制器中附加登錄按鈕邏輯。

override func viewDidLoad() { 
     super.viewDidLoad() 

loginButton = LoginButton(readPermissions: [.publicProfile, .userFriends, .email]) 
     loginButton.center = view.center 
     loginButton.frame.origin = CGPoint(x: loginButton.frame.origin.x,y: loginBtn.frame.origin.y + 80) 
     self.view.addSubview(loginButton) 
     loginButton.delegate = self 

} 

func loginButtonDidCompleteLogin(_ loginButton: LoginButton, result: LoginResult) { 

     switch result { 
     case .success(let grantedPermissions, _, let accessToken): 
      print("facebook success") 
      print(accessToken.authenticationToken) 
      break 
     case .cancelled: 
      print("facebook cancelled") 
      break 

     case .failed(let error): 
      print("facebook error") 
      break 
     } 
} 

func loginButtonDidLogOut(_ loginButton: LoginButton) { 
     print("User has logged out") 
} 

我已經經歷了很多的做題，Github上的問題了，並且有運行到同樣的情況我一些開發商，沒有關於此錯誤的可能結果有任何具體的迴應。到底發生了什麼，是我得到了一個胖胖的LoginResult.cancelled回調，而不是我想要的。

從控制檯輸出，與此相關的是：

-canOpenURL: failed for URL: "fbauth2:/" - error: "The operation couldn’t be completed. (OSStatus error -10814.)" 

任何幫助，將不勝感激。謝謝！

我有一個類似的問題，這是由於我的應用中的AppDelegate中的方法在完成登錄時沒有被Facebook調用。

基礎上tutorial here我認爲你需要改變的AppDelegate的方法如下：

import FacebookCore 

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

... 

    return FacebookCore.SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions) 
} 

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { 

    return FacebookCore.SDKApplicationDelegate.shared.application(app, open: url, options: options) 
} 

進行此更改後，我發現，Facebook的切換回我的應用程序登錄後，並沒有死守一個白色的屏幕。
