ios - 如何确定用户是否在 iPhone 设置中设置了 FB 帐户

Question

我想询问用户是否愿意启用 FB 集成并为他们提供 UISwitch 以表明他们的偏好。但是，我只想在用户实际在 iPhone 设置中设置其 FB 帐户的情况下启用/取消隐藏该选项。一个人如何去检查他们是否做了那么多？

        if(iOSVersion >= 6.0)
        {
                if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
             {
                     NSLog(@"user have filled fb acount details");
             }
             else
            {

                    NSLog(@"settings is empty");
            }   

        }

我想到了。这是对我有用的代码块。我欢迎改进建议:)

self.myStore = [[ACAccountStore alloc] init];
    ACAccountType *acct = [self.myStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
    NSArray *fbAccounts = [self.myStore accountsWithAccountType:acct];

    // Check to make sure the user has a FB account setup, or bail:
    if ([fbAccounts count] == 0) {
        userDoesNotHaveFBAccountSetup = YES;
        self.fbSwitch.enabled = NO;
        [[self fbSwitch] setOn:NO];
        [self viewDidLoad];
    } else {
        userDoesNotHaveFBAccountSetup = NO;
        self.fbSwitch.enabled = YES;
    }
