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:

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()
}
}
}
