Question

我想将图片发布到脸书和推特上。我很喜欢推特，但没有使用SLComposeViewController类的facebook。随着添加图像，我能够将文本和网址发布到Facebook。问题是，当我使用添加图像我无法发布此图像和文本，网址。 SLComposeViewController在我发送时显示图像，文本和URL。我有正确的appId，我没有得到任何错误。但问题仍然存在。我不是问题所在。请帮帮我。

我在我的项目中使用了以下代码来发布图像，它可以正常工作。

    if([SLComposeViewController instanceMethodForSelector:@selector(isAvailableForServiceType)] != nil)
    {
        if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
        {

            SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

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

                    NSLog(@"Cancelled");

                } else

                {
                    NSLog(@"Done");
                }

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

            [controller setInitialText:@"Check out my Christmas Gift!"];
            [controller addImage:@"gift.jpg"];

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

        }

我检查了互联网并注意到最近1或2天内与此问题相关的一些讨论，他们似乎与Facebook有关。因此，如果您的代码将消息和图像成功发布到Twitter，那么请不要担心！你做得对。

  I have resolved through open present-view controller in navigation-bar.it may help you.

 SLComposeViewController *controller = [SLComposeViewController   composeViewControllerForServiceType:SLServiceTypeFacebook];
    [controller setInitialText:shareFrom];
    [controller addImage:self.photoImageView.image];
    [controller addURL:[NSURL URLWithString:dayCareWebsite]];
    dispatch_async(dispatch_get_main_queue(), ^ {

        [self.navigationController presentViewController:controller animated:YES completion:nil];

    });

无法使用SLComposeViewController将图像发布到Facebook？
