Facebook 登录无效范围

Question

I'm using Facebook login, and all of a sudden it stopped working saying "Invalid Scope: user_Friends".

I thought this error was because of the upgrade of the Graph API from v1.0 to v2.0 but my SDK is on the version 3.18 which already comes with GraphAPI v2.0

does any one knows what am I doing wrong? Do I need to make any modifications to be compatible with GraphAPI v2.0?

this is my code I ask for permissions

- (void)viewDidLoad
{
    [super viewDidLoad];
    originalFrame = menuBG.frame;
    NSLog( @"### running FB sdk version: %@", [FBSettings sdkVersion] );
    if (FBSession.activeSession.isOpen)
    {
        NSLog(@"Is Connected");
        flagFaceCon = YES;
    }
    else
    {
        flagFaceCon = NO;
        NSLog(@"Is NOT Connected");
    }

    loginView.readPermissions = @[@"public_profile", @"email", @"user_Friends"];
}

Answer 1

You may also get this error if your app is public but it hasn't been app reviewed yet. Though the docs don't make this entirely obvious. It's a bit fine-print and the error message doesn't clue you into that.

Answer 2

try

user_friends

not

user_Friends

Answer 3

我用于范围 user_Friends，但正确的是 user_friends（小写）。
