ios - Facebook 发帖

Question

这就是我所做的

• 在 Facebook 上创建了一个应用
• 安装了满足所有要求的 FB SDK
• 通过登录按钮登录用户
• 现在我正在尝试使用此处提供的来自此威胁的代码进行发布 How to Post to Facebook on iOS 6 in Objective-C using ACAccountStore class

但是什么也没发生。我是不是漏掉了一步？

这是我正在使用的代码

 if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) //check if Facebook Account is linked
    {
      mySLComposerSheet = [[SLComposeViewController alloc] init]; //initiate the Social Controller
        mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; //Tell him with what social plattform to use it, e.g. facebook or twitter
                [mySLComposerSheet setInitialText:[NSString stringWithFormat:@"Test",mySLComposerSheet.serviceType]]; //the message you want to post
       [mySLComposerSheet addImage:yourimage]; //an image you could post
        //for more instance methodes, go here:https://developer.apple.com/library/ios/#documentation/NetworkingInternet/Reference/SLComposeViewController_Class/Reference/Reference.html#//apple_ref/doc/uid/TP40012205
        [self presentViewController:mySLComposerSheet animated:YES completion:nil];
    }
    [mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
        NSString *output;
        switch (result) {
            case SLComposeViewControllerResultCancelled:
                output = @"Action Cancelled";
                break;
            case SLComposeViewControllerResultDone:
                output = @"Post Successfull";
                break;
            default:
                break;
        } //check if everything worked properly. Give out a message on the state.
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Facebook" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
        [alert show];
    }];

Answer 1

您的setInitialText 方法不正确。如果您使用 stringWithFormat 发布 serviceType，则需要将其添加到带有“%@”的方法中，否则没有任何内容可以显示。

简而言之，只需更改:

[mySLComposerSheet setInitialText:[NSString stringWithFormat:@"Test",mySLComposerSheet.serviceType]];

到:

[mySLComposerSheet setInitialText:[NSString stringWithFormat:@"Test %@",mySLComposerSheet.serviceType]];
