我正在尝试在我的应用程序中实现Facebook登录选项.我按照Parse网站和Facebook开发者页面上的所有说明进行操作.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App时,我得到了这个异常：

这些是我在项目中实际拥有的框架和库：
奇怪的是,如果我从零创建一个新项目,我根本没有问题,登录工作正常.
编辑：我仍在尝试解决这个问题.通过从[PFFacebookUtils initializeFacebookWithApplicationLaunchOptions：launchOptions]更改PFFacebookUtils初始化代码,我设法启动了App而没有错误;到[PFFacebookUtils初始化];但是如果我尝试使用代码[PFFacebookUtils logInInBackgroundWithReadPermissions：nil block：^(PFUser * user,NSError * error){}登录按钮,则会出现另一个异常因未捕获的异常’NSInternalInconsistencyException’而终止app,原因：’你必须通过调用initializeFacebookWithApplicationLaunchOptions来初始化PFFacebookUtils
我正按照建议添加我正在使用的代码：
在我的AppDelegate.m中
#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];
}
解决方法
我经历了同样的斗争,尝试了许多不同的方法来设置Parse与Facebook登录.我不得不说,我没有使用Obj-C的经验,但这是我工作的Swift Parse w / Facebook登录应用程序,我希望能给你一些见解.
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()
}
}
}
