我正在尝试在我的应用程序中实现 Facebook 登录选项。我遵循了 Parse 网站和 Facebook 开发者页面上的所有说明。我添加了框架，修改了 plist 文件并添加了正确的代码，但是当我启动应用程序时，我得到了这个异常:

libc++abi.dylib: terminating with uncaught exception of type NSException

这些是我在我的项目中实际拥有的框架和库:

奇怪的是，如果我从零开始创建一个新项目，我一点问题都没有，并且登录工作正常。

编辑:我仍在努力解决这个问题。我设法通过将 PFFFacebookUtils 初始化代码从 [PFFFacebookUtils initializeFacebookWithApplicationLaunchOptions:launchOptions]; 更改为 [PFFFacebookUtils initialize]; 来成功启动应用程序，但是然后，如果我尝试使用代码 [PFFFacebookUtils logInInBackgroundWithReadPermissions:nil block:^(PFUser *user, NSError *error) {} 出现另一个异常 Termating app due to uncaught exception “NSInternalInconsistencyException”，原因:“您必须通过调用 +initializeFacebookWithApplicationLaunchOptions 来初始化 PFFFacebookUtils”

我正在按照建议添加我正在使用的代码:

在我的 AppDelegate.m

#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <ParseFacebookUtilsV4/PFFacebookUtils.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

// PARSE
[Parse setApplicationId: SMParseApplicationId
              clientKey: SMParseClientId];

// FACEBOOK
[PFFacebookUtils initializeFacebookWithApplicationLaunchOptions:launchOptions];


[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
//*****

// GOOGLE MAP API
[GMSServices provideAPIKey: SMGoolgeMapApiKey];
//*****

return [[FBSDKApplicationDelegate sharedInstance] application:application
                                didFinishLaunchingWithOptions:launchOptions];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                      openURL:url
                                            sourceApplication:sourceApplication
                                                   annotation:annotation];
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
  [FBSDKAppEvents activateApp];
}

最佳答案

我经历过同样的挣扎，并尝试了许多不同的方法来使用 Facebook 登录设置 Parse。不过我不得不说，我没有使用 Obj-C 的经验，但这是我使用 Facebook 登录应用程序运行的 Swift Parse，我希望它能给你一些见解。

在我的 AppDelegate.swift 中:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {

    Parse.setApplicationId("ID", clientKey:"KEY")
    PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
    FBSDKProfile.enableUpdatesOnAccessTokenChange(true)


    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}


func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

func applicationDidBecomeActive(application: UIApplication) {
    FBSDKAppEvents.activateApp()
}

在我的 LoginViewController.swift 中:

//My custom storyboard button
    @IBAction func fbLogin(sender: AnyObject) {

    var permissions = ["public_profile", "email"]
    PFFacebookUtils.logInInBackgroundWithReadPermissions(permissions) {
        (user: PFUser?, error: NSError?) -> Void in
        if let user = user {
            if user.isNew {
                println("User signed up and logged in through Facebook!")
                self.facebookSignUp(user)
            } else {
                println("User logged in through Facebook!")
                self.performSegueWithIdentifier("LoginSuccessful", sender: self)
            }
        } else {
            println("Uh oh. The user cancelled the Facebook login.")
        }
    }
}



override func viewDidLoad() {
    super.viewDidLoad()

    if PFUser.currentUser() != nil {
        moveToNextView() //Segue to next ViewController
    }
}


func facebookSignUp(user: PFUser) -> Void{
    var request = FBSDKGraphRequest(graphPath: "me", parameters: nil)
    var userID:String

    request.startWithCompletionHandler { (connection: FBSDKGraphRequestConnection!, result: AnyObject!, error: NSError!) -> Void in
        if error == nil {
            user["fullName"] = result["name"]
            var facebookUserID = result["id"] as! String
            user["facebookUserID"] = facebookUserID

            user.save()
            self.performSegueWithIdentifier("LoginSuccessful", sender: self)

        } else {
            println(error)
            PFUser.logOut()
        }

    }

}
