推荐答案

我最近实现了gmail api，以在我的tableview中获取gmail联系人及其电子邮件. Gmail api简而言之，这就是为什么您可能没有适当的文档的原因.

I have recently implemented gmail api to fetch gmail contacts and their email in my tableview. Gmail api is depricated, thats why you might have not got any proper documentation for that.

要实现gmail，请使用带有Gdata标头的libGDataTouchStaticLib.a库(在Google上搜索该库，否则向我发送您的电子邮件，我将向您发送其zip).

To implement gmail use libGDataTouchStaticLib.a library, with Gdata headers (search on google for that otherwise send me your email i will send you its zip).

获取gmail详细信息的代码如下

The code to get gmail details are as follows

- (void)getGoogleContacts {

    GDataServiceGoogleContact *service = [self contactService];
    GDataServiceTicket *ticket;

    BOOL shouldShowDeleted = TRUE;

    // request a whole buncha contacts; our service object is set to
    // follow next links as well in case there are more than 2000
    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];
    }

    // update the username/password each time the service is requested
    NSString *username = [txtUserName text];
    NSString *password = [txtPasswrod text];

    [service setUserCredentialsWithUsername:username
                                   password:password];

    return service;
}


// contacts fetched callback
- (void)contactsFetchTicket:(GDataServiceTicket *)ticket
           finishedWithFeed:(GDataFeedContact *)feed
                      error:(NSError *)error {

    if (error) {

        NSDictionary *userInfo = [error userInfo];
        NSLog(@"Contacts Fetch error :%@", [userInfo objectForKey:@"Error"]);
        if ([[userInfo objectForKey:@"Error"] isEqual:@"BadAuthentication"]) {

            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error!"
                                                                message:@"Authentication Failed"
                                                               delegate:self
                                                      cancelButtonTitle:@"Ok"
                                                      otherButtonTitles:nil, nil];
            [alertView show];

        } else {

            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error!"
                                                                message:@"Failed to get Contacts."
                                                               delegate:self
                                                      cancelButtonTitle:@"Ok"
                                                      otherButtonTitles:nil, nil];
            [alertView show];
        }

    } else {

        NSArray *contacts = [feed entries];
        NSLog(@"Contacts Count: %d ", [contacts count]);
        [mutAryGoogleContacts removeAllObjects];
        for (int i = 0; i < [contacts count]; i++) {

            NSMutableDictionary *aDictContactDetails=[NSMutableDictionary dictionary];


            GDataEntryContact *contact = [contacts objectAtIndex:i];
            // Email
            GDataEmail *email = [[contact emailAddresses] objectAtIndex:0];
            NSString* ContactEmail = [email address];
            if (ContactEmail) {
                [aDictContactDetails setObject:ContactEmail forKey:@"email"];




            // Name
            NSString *ContactName = [[[contact name] fullName] contentStringValue];
            if (ContactName) {
                [aDictContactDetails setObject:ContactName forKey:@"friendName"];

            }
            [mutAryGoogleContacts addObject:aDictContactDetails];

            }

        }

       //Push to next vc or do whatever you want
    }


}
