Программно обмениваться видео на facebook с помощью приложения iOS 6?

Question

Я работаю над приложением, где мне нужно обмениваться видео на Facebook. Когда я попробовал Developer.facebook.com для решения, я нашел use the graph api to upload a video in ios. Он делится видео по API-интерфейсу. Будет ли работать API-интерфейс графика в iOS 6? Пожалуйста, предложите. Также укажите любой пример кода, если у вас есть.

Заранее спасибо.

Answer 1

да, вы можете сделать это, Facebook просто выпустила новую систему 3.5, которая будет легко работать на iOS5 и iOS6 http://developers.facebook.com/ios/

Answer 2

Попробуйте с этим я использовал facebook SDK 3.1 https://developers.facebook.com/ios/

.h файл

#import <FacebookSDK/FacebookSDK.h> 
    extern NSString *const SCSessionStateChangedNotificationCamera; 

.m файл

NSString *const SCSessionStateChangedNotificationCamera = @"com.facebook.Scrumptious:SCSessionStateChangedNotification"; 

    -(IBAction)btnFacebookShareClick:(id)sender { 
    if (![self openSessionWithAllowLoginUI:YES]) { 
      [self showLoginView]; 
     } 
    } 

    #pragma mark - 
    #pragma mark - Facebook Method 

    - (void) performPublishAction:(void (^)(void)) action { 
     if ([FBSession.activeSession.permissions indexOfObject:@"publish_actions"] == NSNotFound) { 
      [FBSession.activeSession reauthorizeWithPublishPermissions:[NSArray arrayWithObject:@"publish_actions"] defaultAudience:FBSessionDefaultAudienceFriends completionHandler:^(FBSession *session, NSError *error) { 
       if (!error) { 
        action(); 
       } 
      }]; 
     } 
     else {

     } 
    }
