Try using "source" and not "picture". 尝试使用“来源”而不是“图片”。 Picture is expecting the url string. 图片期待网址字符串。

Hmm I am not user Facebook gonna decode your bitmap image, save the image on their server and make it available on your wall ^^ 嗯,我不是用户Facebook会解码你的位图图像,将图像保存在他们的服务器上,并让它在你的墙上可用^^
Try an URL instead of the NSData data of your image. 尝试使用URL而不是图像的NSData数据。
