使用图形api在Facebook墙上发布图像iphone sdk

我一直在尝试使用facebook图形API在Facebook上发布照片。验证用户后，我做的是通过抛出异常以下使用图形api在Facebook墙上发布图像iphone sdk

 NSMutableDictionary *variables = [[NSMutableDictionary alloc]init]; 
     [variables setObject:@"some text" forKey:@"message"]; 
     [variables setObject:@"some link" forKey:@"link"]; 
     [variables setObject:[UIImage imageNamed:@"[email protected]"] forKey:@"picture"]; 

     NSString *str = @"me/feed"; 
     NSLog(@"str: %@", str); 
     FbGraphResponse *resp = [self.fbGraph doGraphPost:str withPostVars:variables]; 
     NSLog(@"resp: %@", resp.htmlResponse);

但我的应用程序崩溃：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: -[UIImage dataUsingEncoding:]: unrecognized selector sent to instance 0x11545140'

所以有些人可以帮我我如何在Facebook上墙一些消息一起张贴图片使用图形API。

这是使用图形API？如果是的话，我可以在哪里找到FBRequest？ – Gani414

是的，它是.https：//developers.facebook.com/docs/reference/ios/3.1/class/FBRequest/ –

使用下面的代码

NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:3]; 

//create a UIImage (you could use the picture album or camera too) 
//UIImage *picture =selectimage.image; 
UIImage *picture =[self scaleAndRotateImage:selectimage.image]; 

FbGraphFile *graph_file = [[FbGraphFile alloc] initWithImage:picture]; 

    [variables setObject:graph_file forKey:@"file"]; 

    [variables setObject:myPost.text forKey:@"message"]; 

    FbGraphResponse *fb_graph_response = [fbGraph doGraphPost:@"me/photos" withPostVars:variables];

谢谢阿曼。它对我来说工作得很好。但为什么我们需要scaleAndRotateImage。如果我这样做，它会抛出一个ARC错误。任何方式我删除并直接添加图像。谢谢。 – Gani414
