Iphone 无法使用SLComposeViewController将图像发布到facebook？

我想把图片发布到facebook和twitter上。我可以使用twitter，但不能使用SLComposeViewController类使用facebook。没有了添加图像，我就可以将文本和url发布到facebook上。问题是，当我使用“添加图像”时，我无法发布此图像以及文本、url。SLComposeViewController在我发送时显示图像、文本和url。我有正确的appId，没有收到任何错误。但问题仍然存在。我不知道问题出在哪里。请帮帮我

我在我的项目中使用了下面的代码来发布图像，效果很好

    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];

        }

您只需尝试以下教程

我查看了互联网，发现最近一两天有一些讨论与这个问题有关，它们似乎与Facebook bug有关。因此，如果您的代码成功地将消息和图像发布到Twitter，那么不要担心！你做得对

谢谢您的重播。我已经添加了你的代码，但没有得到图像。但当我删除addImage:method时，我在我的脸书中收到了一条消息。你只需检查该图像是否存储在facebook相册中，而不是wall@PrasadG我增加了两个教程，看看吧，谢谢你的建议。你说得对。这些照片在相册中。此代码没有解决我的问题。检查

  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]];
