如何将文本和图片发布到 Facebook 新闻源

Question

在将 Facebook 整合到 iOS 应用程序方面我还是个新手。我已经阅读了 3 本书，研究了 Facebook 示例，研究了 Facebook 教程，但我不了解 Facebook 集成。我了解如何在 Facebook 上注册应用程序，但我不了解将文本和图片发布到用户新闻提要的代码。我试图了解 Facebook 的教程，但它们都是基于 Xcode 和 iOS 版本的，它们不是最新的。 Facebook 的教程也不一致（例如，登录教程与发布教程的变量不匹配等）。我确实了解如何将文本添加到“initialText”，但在此变量中提供默认文本违反 Facebook 政策。谁能解释如何在 Xcode 中向用户的新闻提要发布文本和图片？

谢谢！

你试过这个吗？

if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {

            SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

            SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
                if (result == SLComposeViewControllerResultCancelled) {

                    NSLog(@"ResultCancelled");

                } else

                {
                    NSLog(@"ResultSuccess");
                }

                [controller dismissViewControllerAnimated:YES completion:Nil];
            };
            controller.completionHandler =myBlock;
            [controller setInitialText:@"Learn iOS6 Social Framework integration"];
            [controller addURL:[NSURL URLWithString:@"http://google.com"]];
            [controller addImage:[UIImage imageNamed:@"myimage.jpeg"]];
            [self presentViewController:controller animated:YES completion:Nil];

        }
        else{

            //NSLog(@"UnAvailable");
            UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Facebook"
                                                          message:[NSStringstringWithFormat:@"The application cannot post message at the moment. Please login under setting section with your Facebook account."]
                                                         delegate:nil
                                                cancelButtonTitle:@"OK"
                                                otherButtonTitles:nil];
            [alert show];
            [alert release];
        }

在您的项目中导入社交框架。

- (void)ShareOnFB    
{         
    SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

    SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
        if (result == SLComposeViewControllerResultCancelled) {

            NSLog(@"Cancelled");

        } else

        {
            NSLog(@"Done");
            //Adding the Text to the facebook post value from iOS

        }

        [controller dismissViewControllerAnimated:YES completion:Nil];
    };
    controller.completionHandler =myBlock;

    NSString *fb=[NSString stringWithFormat:@"you can add your text hereand change it as and when needed"];

    [controller setInitialText:fb];      



    //Adding the Image to the facebook post value from iOS

    [controller addImage:yourImageView.image];


    [self presentViewController:controller animated:YES completion:Nil];


}
