Question

我正在尝试使用Parse.com为我的ios应用程序实现Facebook登录，并且还没有成功，因为没有太多关于如何逐步实现目标c。

所以我希望这个问题对他人也有帮助。

在app delegate我有：

didFinishLaunchingWithOptions:

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

    [PFFacebookUtils initializeFacebookWithApplicationLaunchOptions: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];
}

现在这里是我不确定将下面的代码放在哪个方法的地方：

1]对于我的Facebook登录按钮，我在故事板中的loginViewController中创建了一个视图，并使该视图成为一个FBlogin按钮。然后我将该视图连接到此IBOutlet

@property (weak, nonatomic) IBOutlet FBSDKLoginButton *loginButton;

然后在loginView.m中我有这个：

- (void)viewDidLoad {
    [super viewDidLoad];

    FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];

    self.loginButton.readPermissions = @[@"username", @"email", @"password"];    
}

用它登录用户，但没有更多的事情发生回到登录界面，Facebook用户登录到Facebook。所以我激活了按钮进入视图，现在我不确定何时放入注册登录的代码。

- (void)_loginWithFacebook{ 
    [PFFacebookUtils logInInBackgroundWithReadPermissions:@[@"username", @"email", @"password"] block:^(PFUser *user, NSError *error) {
        if (!user) {
            //  NSLog(@"Uh oh. The user cancelled the Facebook login.");
        } else if (user.isNew) {
            NSString *message = [NSString stringWithFormat:@"@%@ logged in! (%@)",
                                 [PFUser currentUser].username, [PFUser currentUser].objectId];
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Logged in!"
                                                            message:message
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles:nil];
            [alert show];

        } else {
            //  NSLog(@"User logged in through Facebook!");
            [self.navigationController popToRootViewControllerAnimated:NO];
        }
    }];

}

- (void)saveFacebookUser:(PFUser *)user UserData:(NSDictionary *)userData Picture:(NSString *)pictureUrl Thumbnail:(NSString *)thumbnailUrl
{
    NSString *username = userData[@"username"];
    NSString *email = userData[@"email"];

    user.username = username;
    user.username = [username lowercaseString];
    user.email = email;
    [user saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error)
     {
         if (error == nil)
         {

         }
         else {

         }
     }];

}

一旦用户登录，我想让他们转到rootView，并让facebook用户成为PFUser.CurrentUser并显示用户名

因此，请帮助我登录用户将其带入rootView并将其用户名保留为解析用户。

您是否在Info.plist文件中添加了键值???

Info.plist必须如下所示：

此键值通过以下步骤添加到info.plist文件中：

转到项目导航栏（左侧面板）
右键单击info.plist文件
选择＆＃34; Open As＆＃34;并单击＆＃34;源代码＆＃34;
将代码放在<dict>＆amp;之间</dict>以下
