尝试使用以下代码通过 Facebook + Parse 登录:

我注意到在单击“使用 Facebook 登录”按钮时，它会在控制台中显示两次。

-canOpenURL: failed for URL: "fbauth2://" - error: "This app is not allowed to query for scheme fbauth2"

这是我的代码:

- (IBAction)loginWithFacebook:(id)sender {
        // Set permissions required from the facebook user account
        NSArray *permissionsArray = @[ @"user_about_me", @"user_relationships", @"user_birthday", @"user_location"];

        // Login PFUser using Facebook
        [PFFacebookUtils logInWithPermissions: permissionsArray block:^(PFUser * _Nullable user, NSError * _Nullable error) {
            if (!user) {
                NSLog(@"Uh oh. The user cancelled the Facebook login.");
            } else if (user.isNew) {
                NSLog(@"User signed up and logged in through Facebook!");
            } else {
                NSLog(@"User logged in through Facebook!");
            }

        }];


}

我已将其添加到我的 plist 中，就像在其他主题中找到的那样，但仍然出现相同的错误。 [[编辑以回答下面仍然相同的问题]]

最佳答案

如果您使用 iOS SDK 9.0 重新编译，如果您使用的是 SDK v4.5 或更早版本，请将以下内容添加到应用程序的 plist 中:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fbapi20130214</string>
    <string>fbapi20130410</string>
    <string>fbapi20130702</string>
    <string>fbapi20131010</string>
    <string>fbapi20131219</string>    
    <string>fbapi20140410</string>
    <string>fbapi20140116</string>
    <string>fbapi20150313</string>
    <string>fbapi20150629</string>
    <string>fbauth</string>
    <string>fbauth2</string>
    <string>fb-messenger-api20140430</string>
</array>

如果您使用的是早于 v4.6 版本的 FBSDKMessengerShareKit，请同时添加

<string>fb-messenger-platform-20150128</string>
<string>fb-messenger-platform-20150218</string>
<string>fb-messenger-platform-20150305</string>

如果您使用的是v4.6.0的SDK，您只需添加:

<key>LSApplicationQueriesSchemes</key>
<array>
        <string>fbapi</string>
        <string>fb-messenger-api</string>
        <string>fbauth2</string>
        <string>fbshareextension</string>
</array>
