Facebook登录问题iOS9+；作语法分析

尝试使用以下代码使用Facebook+Parse登录：

我注意到，当单击“使用Facebook登录”按钮时，该按钮会在控制台中显示两次

-canOpenURL:URL:“fbauth2://”失败-错误：“不允许此应用查询方案fbauth2”

这是我的密码：

- (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!");
            }

        }];


}

我已经将它添加到我的plist中，就像在其他主题中一样，但是仍然得到相同的错误[[编辑以回答以下仍然相同的问题]]

如果您使用iOS SDK 9.0重新编译，如果您使用的是SDK v4.5或更高版本，请在应用程序的plist中添加以下内容：

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fbapi20130214</string>
    <string>fbapi20130410</string>

LSApplicationQueriesSchemes
如您所说更改了它，但仍然运行到相同的问题。古怪的请参阅“编辑到我的帖子”。@Jamie22您可以尝试以下操作：1）检查您的Facebook SDK版本，2）检查处理openURL的appleDelegate 3）深度清理您的项目并重建：）希望它能工作
