您好我已成功加入Google +。现在我试图获取朋友的详细信息，如电子邮件，图片，名称。但是收到错误。
任何人都可以帮助我，我犯了错误 -
我试过这段代码 -
- (void)finishedWithAuth: (GTMOAuth2Authentication *)auth
error: (NSError *) error {
self.plusService.authorizer = auth;
NSLog(@"%@",[NSString stringWithFormat:@"Email---> %@\n\n",[GPPSignIn sharedInstance].authentication.userEmail]);
NSLog(@"Received error %@ and auth object ---> %@\n\n",error, auth);
// 1.创建| GTLServicePlus |向Google +发送请求的实例。
GTLServicePlus* plusService = [[GTLServicePlus alloc] init] ;
plusService.retryEnabled = YES;
// 2.设置有效的| GTMOAuth2Authentication |作为作者的对象。
[plusService setAuthorizer:[GPPSignIn sharedInstance].authentication];
// 3.使用＆＃34; v1＆＃34; Google+ API的版本。*
plusService.apiVersion = @"v1";
GTLQueryPlus *query = [GTLQueryPlus queryForPeopleListWithUserId:@"me" collection:kGTLPlusCollectionVisible];
[plusService executeQuery:query
completionHandler:^(GTLServiceTicket *ticket,
GTLPlusPeopleFeed *person,
NSError *error) {
if (error)
{
GTMLoggerError(@"Error: %@", error);
}
else {
NSArray *peopleList = person.items;
NSLog(@"--People_List--->%@",peopleList);
}}];
}
获取错误 -

获取朋友详细信息，您可以使用Google通讯录API
在那个用途中
#import "GDataFeedContact.h"
#import "GDataContacts.h"
类文件
然后使用此代码获取数据
-(void)getGoogleContacts
{
GDataServiceGoogleContact *service = [self contactService];
GDataServiceTicket *ticket;
BOOL shouldShowDeleted = TRUE;
const int kBuncha = 2000;
NSURL *feedURL = [GDataServiceGoogleContact contactFeedURLForUserID:kGDataServiceDefaultUser];
GDataQueryContact *query = [GDataQueryContact contactQueryWithFeedURL:feedURL];
[query setShouldShowDeleted:shouldShowDeleted];
[query setMaxResults:kBuncha];
ticket = [service fetchFeedWithQuery:query
delegate:self
didFinishSelector:@selector(contactsFetchTicket:finishedWithFeed:error:)];
[self setContactFetchTicket:ticket];
}
- (void)setContactFetchTicket:(GDataServiceTicket *)ticket
{
mContactFetchTicket = ticket;
}
- (GDataServiceGoogleContact *)contactService
{
static GDataServiceGoogleContact* service = nil;
if (!service) {
service = [[GDataServiceGoogleContact alloc] init];
[service setShouldCacheResponseData:YES];
[service setServiceShouldFollowNextLinks:YES];
}
//pass the useremail and password.here
NSString *username = @"youremai@gmail";
NSString *password = @"yourpassword";
[service setUserCredentialsWithUsername:username
password:password];
return service;
}
