ios - Facebook SDK 使用 Swift 3 iOS 10 登录

Question

我通过 Cocoapods 安装了 Facebook 的 Swift SDK:

pod 'FacebookCore', :git => "https://github.com/facebook/facebook-sdk-swift"
pod 'FacebookLogin', :git => "https://github.com/facebook/facebook-sdk-swift"

我已按照 Facebook 的 Swift SDK (https://developers.facebook.com/docs/swift/login) 中的登录说明进行操作，但无法正常工作。

在我的 View Controller 中，我有以下内容:

@objc fileprivate func facebookSignIn() {
    let loginManager = LoginManager()
    print("LOGIN MANAGER: \(loginManager)")
    loginManager.logIn([ .publicProfile, .email ], viewController: self) { loginResult in
        print("LOGIN RESULT! \(loginResult)")
        switch loginResult {
        case .failed(let error):
            print("FACEBOOK LOGIN FAILED: \(error)")
        case .cancelled:
            print("User cancelled login.")
        case .success(let grantedPermissions, let declinedPermissions, let accessToken):
            print("Logged in!")
            print("GRANTED PERMISSIONS: \(grantedPermissions)")
            print("DECLINED PERMISSIONS: \(declinedPermissions)")
            print("ACCESS TOKEN \(accessToken)")
        }
    }
}

“登录管理器:等等。”当我单击按钮并打开 Web View 时打印。我可以通过 Facebook 登录，然后 Web View 变为空白，什么也没有发生。该应用程序显示在我的 Facebook 应用程序中，因此已经进行了一些授权，但是如果我在 Web View 中单击“完成”按钮，回调的结果是 .cancelled 和“用户取消登录。 “打印出来。

我已将钥匙串(keychain)共享添加到我的权利中，并且更新了我的 info.plist:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string> [ FB STRING ] </string>
        </array>
    </dict>
</array>
<key>FacebookAppID</key>
<string>[ APP ID ]</string>
<key>FacebookDisplayName</key>
<string>[ APP NAME ]</string>
<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fb-messenger-api</string>
    <string>fbauth2</string>
    <string>fbshareextension</string>
</array>

我什至更改了我的 NSAppTransportSecurity 设置。

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

我知道这是 iOS 9 Facebook login simulator -canOpenURL: failed for URL: "fbauth2:///" - error: "(null)" 的副本和 How to use Facebook iOS SDK on iOS 10但是那里的解决方案似乎都不适合我，除非我错过了什么？任何建议表示赞赏。

还打印了几个错误:

[App] if we're in the real pre-commit handler we can't actually add any new fences due to CA restriction


[error] error: (6922) I/O error for database at /var/mobile/Containers/Data/Application/F3D8E126-B0CC-4C06-81A5-D7A7F849B3BD/Documents/OfflineModel2.sqlite.  SQLite error code:6922, 'disk I/O error'

当我的设备上没有安装 FB 应用程序时，我得到:

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

Answer 1

Swift 3 和 Swift 4

将此添加到您的 AppDelegate.swift

import FBSDKCoreKit
import FBSDKLoginKit

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
   return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

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