ios - 使用 Facebook SDK 3.0(测试版)、Xcode 4.3.2 在我自己的 Facebook 墙上发布图像

Question

我正在使用 Facebook SDK 3.0(还带有 Xcode 4.3.2，并且禁用了 ARC)，我已经编写了登录代码并在我自己的 Facebook 墙上发布短信(上面的代码)，一切运行完美:

        - (IBAction)loginFacebook:(id)sender {

    // Initiate a Facebook instance
    Facebook *facebook = [[Facebook alloc] initWithAppId:@"My_App_ID" andDelegate:nil];

    // Set the session information for the Facebook instance
    facebook.accessToken = self.session.accessToken;
    facebook.expirationDate = self.session.expirationDate;

    // Put together the dialog parameters
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"I'm using Emoji-Smileys", @"name",
                                   @"Facebook for iOS", @"caption",
                                   @"Check out the application Emoji-Smileys for iOS to enable emoji keyboard, and make fun messages! There are 460 smileys!", @"description",
                                   @"http://m.facebook.com/apps/hackbookios/", @"link",
                                   @"http://a365.phobos.apple.com/us/r30/Purple/v4/fa/96/4c/fa964c2a-3a48-4f6d-7789-d3105a392a9f/mzl.evuvwyjk.png?downloadKey=1343552764_471c078e9d07fde2b00bd3f1ee1d88a7", @"picture", 
                                   nil];    

    // Invoke the dialog
    [facebook dialog:@"feed" andParams:params andDelegate:self];
        }

        - (FBSession *)createNewSession
        {
    self.session = [[FBSession alloc] init];
    return self.session;
        }

        - (void)sessionStateChanged:(FBSession *)session 
                      state:(FBSessionState) state
                      error:(NSError *)error
        {
    switch (state)         {
        case FBSessionStateOpen:
            if (!error)         {
                // We have a valid session
                NSLog(@"User session found");
                    }
            break;
        case FBSessionStateClosed:
        case FBSessionStateClosedLoginFailed:
            [session closeAndClearTokenInformation];
            self.session = nil;

            [self createNewSession];
            break;
        default:
            break;
            }

    if (error)         {
        UIAlertView *errorAlert = [[UIAlertView alloc] 
                                  initWithTitle:@"Error"
                                  message:error.localizedDescription
                                  delegate:nil
                                  cancelButtonTitle:@"OK"
                                  otherButtonTitles:nil];
        [errorAlert show];
            }    
        }

        - (void) openSession         {

    [self.session openWithCompletionHandler:
     ^(FBSession *session, FBSessionState state, NSError *error) {
         [self sessionStateChanged:session state:state error:error];
     }]; 
        }

        - (BOOL)application:(UIApplication *)application 
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication 
         annotation:(id)annotation 
        {
            return [self.session handleOpenURL:url]; 

        }

好吧，现在，我想知道如何发布我在应用程序中提供的图像，不需要使用 UIImagePickerViewController，我不想选择图像。我不知道我是否需要publish_stream、read_stream或user_likes权限或其他权限。

预先感谢您的帮助。

干杯。

您可以使用此代码，这对我有帮助:

[FBRequestConnection startForUploadPhoto:myImg.image
                                   completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                                       if (!error) {
                                           // is success do something...
                                       } else {
                                          // If some error , do something...
                                       }
                                   }];

myImg 是您的图像，您可以将其替换为:

[UIImage imageNamed:@"image.jpg"]
