我正在使用FB SDK并在从我的应用上传FB图片上的图片时收到错误 在我的视图中加载我有和UIImageView有一个图像，我需要在FB上发布视图的代码加载
ImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 65, 65)];
ImageView.center = CGPointMake(42, 43);
[View addSubview:ImageView];
在我的FB帖子中我做了这个
UIImage *image = [[UIImage alloc]init];
image = ImageView.image;
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithCapacity:3];
[params setObject:@"LINK_HERE" forKey:@"link"];
// due to this line below, i am getting an error :
// "[UIImage length]: unrecognized selector sent to instance 0x170fa0e0"
// and if use http link instead of image(UIImage) it works, but i want to use my image
[params setObject:image forKey:@"picture"];
[params setObject:@"NAME_HERE" forKey:@"name"];
[params setObject:@"DEC_HERE" forKey:@"description"];
// Invoke the dialog
[self.facebook dialog:@"feed" andParams:params andDelegate:self];
我应该如何在这段代码中使用我的UIImage ......任何想法？

您只能在Facebook对话框方法中上传基于URL的图片。应用程序内或应用程序包内生成的图像无法上传..
要上传这些图片，您必须使用图API
示例代码
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
image, @"source",
@"caption desc", @"message",
nil];
[facebook requestWithGraphPath:[NSString stringWithFormat:@"/me/photos?access_token=%@", self.facebook.accessToken]
andParams:params andHttpMethod:@"POST" andDelegate:self];

您可以像这样发布图片
UIImage *imgSource = {insert your image here};
NSString *strMessage = @"Images Description";
NSMutableDictionary* photosParams = [NSMutableDictionary dictionaryWithObjectsAndKeys:
imgSource,@"source",
strMessage,@"message",
nil];
[self.facebook requestWithGraphPath:@"me/photos"
andParams:photosParams
andHttpMethod:@"POST"
andDelegate:self];
