ios - Beta 测试、Facebook 登录、Parse。某些用户的 Facebook 信息未保存到 Parse。 swift

Question

我正在进行 Beta 测试，到目前为止，已有 5 位用户完全成功登录和使用该应用程序。但是，3 个用户的 Facebook 信息未保存到 Parse，并且当他们尝试转移到加载用户个人资料的 VC 时，应用程序崩溃。我不明白发生了什么事。这是我的登录代码，它会显得非常业余和困惑，所以预先道歉! (新手但正在尝试)应用程序委托(delegate):

import UIKit
import Bolts
import Parse
import ParseUI
import FBSDKCoreKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

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

// code in here to check devices just left it out as it was too much information to paste.
    }

    // parse info and connection

    Parse.enableLocalDatastore()

    Parse.setApplicationId("",
        clientKey: "")


    PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)

    PFUser.enableAutomaticUser()

    let defaultACL = PFACL();

    defaultACL.setPublicReadAccess(true)

    PFACL.setDefaultACL(defaultACL, withAccessForCurrentUser:true)


    if application.applicationState != UIApplicationState.Background {

        let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus")
        let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:")
        var noPushPayload = false;
        if let options = launchOptions {
            noPushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil;
        }
        if (preBackgroundPush || oldPushHandlerOnly || noPushPayload) {

    installation.setDeviceTokenFromData(deviceToken)
    installation.saveInBackground()

    PFPush.subscribeToChannelInBackground("") { (succeeded: Bool, error: NSError?) in

        } else {
            print("ParseStarterProject failed to subscribe to push notifications on the broadcast channel with error = %@.", error)
        }
    }
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    if error.code == 3010 {
        print("Push notifications are not supported in the iOS Simulator.")
    } else {
        print("application:didFailToRegisterForRemoteNotificationsWithError: %@", error)
    }
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    PFPush.handlePush(userInfo)

    }
}

func application(application: UIApplication,
    openURL url: NSURL,
    sourceApplication: String?,

查看 Controller :

import UIKit

import FBSDKCoreKit
import FBSDKShareKit

import ParseUI

class LoginViewController: UIViewController {

var firstName: String!
var lastName: String!

@IBAction func logInWithFacebook(sender: AnyObject) {

    let permissions = ["public_profile", "email"]


    PFFacebookUtils.logInInBackgroundWithReadPermissions(permissions, block: {

        (user: PFUser?, error: NSError?) -> Void in

        if let error = error {

            print(error)

        } else {
            // user successfully signed in:


            if let user = user {
              self.performSegueWithIdentifier("registerFacebookSegue", sender: self)

            }

                }
    })


}

override func viewDidAppear(animated: Bool) {

    //to log user out

  //  PFUser.logOut()

    // segue if user is logged in:


    if let username = PFUser.currentUser()?.username {


            self.performSegueWithIdentifier("loggedInProfileSegue", sender: self)

    }


}

override func viewDidLoad() {
super.viewDidLoad()



    if(FBSDKAccessToken.currentAccessToken() != nil) {

        print("user logged in")
    } else {
        print("user not logged in")
    }
}


override func prefersStatusBarHidden() -> Bool {
    return true
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

从无法正常工作的用户那里获取 Facebook 密码，并尝试使用 xcode 登录并且连接的手机出现此错误:

问题是我在请求中要求提供电子邮件，但并非所有 Facebook 帐户都有。 a. 有效的电子邮件地址和 b.任何链接的电子邮件地址。所以我不得不删除这个请求并要求用户单独输入他们的电子邮件地址。
