需要在iOS開發中集成Gmail賬戶的建議

Question

我是iOS編程新手，只想做些有趣的事情。 我想開發一個iPhone的郵件客戶端應用程序，它可以添加電子郵件帳戶，如Gmail和雅虎等。我在網上搜索了一段時間，也發現了一些answers，在我深入細節之前，我只希望有相似經歷的人給我一些關於哪種方法最好的建議。

感謝

我最近實施的Gmail API來獲取Gmail聯繫人和他們在我的tableview電子郵件。 Gmail api被刪除，這就是爲什麼你可能沒有任何適當的文件。

要實現gmail使用libGDataTouchStaticLib.a圖書館，與Gdata標題（谷歌搜索，否則發送給我你的電子郵件，我會給你它的zip）。

代碼即可獲得Gmail的詳情如下

- (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 
    } 


}
