Question

我的应用程序允许典型注册（电子邮件，用户名，密码等），但也可以通过Parse启用Facebook / Twitter注册/唱歌。如果可能的话，我想避免强迫用户在Facebook或Twitter登录时两次登录。目前，我添加了“Scringo”的程序化注册功能，使用与我的应用程序相同的凭据将用户签入“scringo”;然而。如果他们与Facebook注册怎么办？对于用户来说，使用Facebook登录，然后滑动条形图并且访问消息传递组件以强制再次使用Facebook登录，这似乎非常令人困惑。

这就是我目前所拥有的，无论如何都要链接Facebook / Twitter登录过程，以便Parse只需按一个按钮即可获得Scringo的信息吗？

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

[Parse setApplicationId:@"...gzPI7Omoxc..."
              clientKey:@"...s22ZqIbM7n..."];

[PFTwitterUtils
 initializeWithConsumerKey:@"...W4XjjpHz..."
            consumerSecret:@"...Czjtht7v5..."];

[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
[PFFacebookUtils initializeFacebook];

[self configureNavigationBar];

[Scringo initWithAppId:@"...N2cCMhW1Bv..." completion:^{
    [Scringo addSidebar:self.window toLeft:YES];
     PFUser *currentUser = [PFUser currentUser];
    if (! [ScringoUser currentUser].isAuthenticated) {
        [ScringoUser signUpWithEmail:currentUser.email userName:currentUser.username password:@"notforyou" completion:^(ScringoUser *aUser, BOOL isSuccess) {
            if (isSuccess) {
                [currentUser setObject:aUser.userId forKey:@"ScringoUserId"];
                [currentUser saveInBackground];
            }
        }];
    }
     }];

return YES;
}

原来SDK中有一个方法（我只是忽略了它）

[Scringo connectFacebook]

如果该应用已成功登录facebook，则也可以通过调用此方式验证Scringo。

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

[Parse setApplicationId:@"gzPI7OmoxcSYqQGWASjzVd8lP5q8FVJqh2ZLsXnp"
              clientKey:@"s22ZqIbM7n8SN1End57vmTmmeL55YnIen7dmMhIR"];

[PFTwitterUtils
 initializeWithConsumerKey:@"W4XjjpHzG03bWK8R0iPvs27Yy"
            consumerSecret:@"Czjtht7v58yfZ00QV5Gkumfdy8RauCyPllYh5SPm00I3M6fkPP"];

[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
[PFFacebookUtils initializeFacebook];

[self configureNavigationBar];

[Scringo initWithAppId:@"cvOV3lLwQN2cCMhW1BvnW2eWnyoiLNgA" completion:^{
    [Scringo addSidebar:self.window toLeft:YES];
     PFUser *currentUser = [PFUser currentUser];
    if (! [ScringoUser currentUser].isAuthenticated) {
        if (currentUser) {
            if (currentUser.email) [Scringo connectFacebook];
        else
        [ScringoUser signUpWithEmail:currentUser.email userName:currentUser.username password:@"notforyou" completion:^(ScringoUser *aUser, BOOL isSuccess) {
            if (isSuccess) {
                [currentUser setObject:aUser.userId forKey:@"ScringoUserId"];
                [currentUser saveInBackground];
            }
        }];
        }
    }
     }];

return YES;
}

假设PFUser已经存在，所以我也为登录用户首次登录的用户添加了相同的呼叫

- (void)logInViewController:(PFLogInViewController *)logInController didLogInUser:(PFUser *)user {
[self dismissViewControllerAnimated:YES completion:^{
    if (!self.currentUser.email) [Scringo connectFacebook];
}];
}

经过测试和工作。

Scringo和Parse：如何同时进行Facebook登录？
