获取在 - （void）getPeopleInfo中出现以下错误。

我在 ViewController.m中编写了以下代码

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.


    GPPSignIn *signIn = [GPPSignIn sharedInstance];
    signIn.shouldFetchGooglePlusUser = YES;
    //signIn.shouldFetchGoogleUserEmail = YES;  // Uncomment to get the user's email

    // You previously set kClientId in the "Initialize the Google+ client" step
    signIn.clientID = kClientId;

    // Uncomment one of these two statements for the scope you chose in the previous step
    signIn.scopes = @[ kGTLAuthScopePlusLogin];  // "https://www.googleapis.com/auth/plus.login" scope
    signIn.scopes = @[ @"profile" ];            // "profile" scope

    // Optional: declare signIn.actions, see "app activities"
    signIn.delegate = self;

    [signIn trySilentAuthentication];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


-(void)refreshInterfaceBasedOnSignIn
{
    if ([[GPPSignIn sharedInstance] authentication]) {
        // The user is signed in.
        NSLog(@"Login");
        self.signInButton.hidden = YES;
        // Perform other actions here, such as showing a sign-out button

        [self getPeopleInfo];
    } else {
        self.signInButton.hidden = NO;
        // Perform other actions here
    }
}

- (void)finishedWithAuth: (GTMOAuth2Authentication *)auth
                   error: (NSError *) error
{
    NSLog(@"Received error %@ and auth object %@",error, auth);
    if (error) {
        // Do some error handling here.
    } else {
        [self refreshInterfaceBasedOnSignIn];
    }
}

- (void)signOut {
    [[GPPSignIn sharedInstance] signOut];
}


- (void)disconnect {
    [[GPPSignIn sharedInstance] disconnect];
}

- (void)didDisconnectWithError:(NSError *)error {
    if (error) {
        NSLog(@"Received error %@", error);
    } else {
        // The user is signed out and disconnected.
        // Clean up user data as specified by the Google+ terms.
    }
}

-(void)getPeopleInfo
{
    GTLServicePlus* plusService = [[GTLServicePlus alloc] init];
    plusService.retryEnabled = YES;

    [plusService setAuthorizer:[GPPSignIn sharedInstance].authentication];


    GTLQueryPlus *query =
    [GTLQueryPlus queryForPeopleListWithUserId:@"me"
                                    collection:kGTLPlusCollectionVisible];
    [plusService executeQuery:query
            completionHandler:^(GTLServiceTicket *ticket,
                                GTLPlusPeopleFeed *peopleFeed,
                                NSError *error) {
                if (error) {
                    GTMLoggerError(@"Error: %@", error);
                } else {
                    // Get an array of people from GTLPlusPeopleFeed
                    NSArray* peopleList = [peopleFeed.items mutableCopy];

                    NSLog(@"peopleList:%@", peopleList);
                }
            }];
}

推荐答案

之后调用以下方法登录成功，对我来说，我正在使用以下方法获取好友列表

Call the following method, after login success, for me, i am getting friends list using below method

-(void)finishedWithAuth: (GTMOAuth2Authentication *)auth
                   error: (NSError *) error {


GTLServicePlus* plusService = [[GTLServicePlus alloc] init];

    plusService.retryEnabled = YES;

    [plusService setAuthorizer:[GPPSignIn sharedInstance].authentication];
    GTLQueryPlus *query =
    [GTLQueryPlus queryForPeopleListWithUserId:@"me"
                                    collection:kGTLPlusCollectionVisible];
    [plusService executeQuery:query
            completionHandler:^(GTLServiceTicket *ticket,
                                GTLPlusPeopleFeed *peopleFeed,
                                NSError *error) {
                if (error) {
                    GTMLoggerError(@"Error: %@", error);
                } else {
                    // Get an array of people from GTLPlusPeopleFeed
                    NSArray* peopleList = peopleFeed.items;
                    NSLog(@"peopleList %@ ",peopleList);

                }
            }];

}
