Posting an image to facebook in iPhone - iphone

Question

Hi I am using this piece of code to post an image to facebook
UIImage *image_LocalSharePhoto = [[UIImage alloc]initWithData:sharedSingleton.dataResultImage];
NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
#"Put Captions On Pics", #"name",
#"Put Captions On Pics", #"caption",
image_LocalSharePhoto,#"picture",
#"I created this fun photo using a FREE app http://bit.ly/CapsPics. #PutCapsOnPics via #PutCapsOnPics", #"description",
nil];
NSString *attachmentStr = [jsonWriter stringWithObject:attachment];
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"532872463436844", #"api_key",
#"Share on Facebook", #"user_message_prompt",
attachmentStr, #"attachment",
nil];
[facebook dialog: #"feed" andParams:params andDelegate:self];
It opens up facebook page but do not show anything to share or post. Can some one help. Thanks!

if you are using facebook's api , I am able to share the images on user's timeline using following code ... Please review the code if it can help ..
include
// aryFetchedImages = Array of images which needs to be posted on Facebook
NSMutableDictionary* params = [[NSMutableDictionary alloc] init];
for (int i = 0; i < aryFetchedImages.count ; i++)
{
[params setObject:UIImageJPEGRepresentation([aryFetchedImages objectAtIndex:i], 50.0f) forKey:#"picture"];
[FBRequestConnection startWithGraphPath:#"me/photos"
parameters:params
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error)
{
if (error)
{
//showing an alert for failure
#ifdef DEBUG
NSLog(#"Unable to share the photo please try later - Fail %#",error);
#endif
}
else
{
//showing an alert for success
#ifdef DEBUG
NSLog(#"Photo %# uploaded on Facebook Successfully",UIImageJPEGRepresentation([aryFetchedImages objectAtIndex:i], 50.0f));
#endif
}
}];
}

if you are using old facebook Method you can wall post like bellow Methid:-
NSArray* permissions = [NSArray arrayWithObjects:#"publish_stream", #"user_photos", nil];
[facebook authorize:permissions];
now to Post image At your Button Click or your logic like:-
-(IBAction)ActionPostWallPhoto
{
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
ImageView.image, #"picture",
nil];
[[objAppdele facebook] requestWithGraphPath:#"me/feed" andParams:params andHttpMethod:#"POST" andDelegate:self];
}
and if you are using new facebook API then you can use bellow Method:-
NSMutableDictionary *postTest = [[NSMutableDictionary alloc]init];
[postTest setObject:[NSString stringWithFormat#"Your message"] forKey:#"message"];
[postTest setObject:#"" forKey:#"picture"];
[postTest setObject:#"" forKey:#"name"];
[postTest setObject:#"APPID" forKey:#"app_id"];
NSString *userFBID =[NSString stringWithFormat:#"%#",[allInfoDict objectForKey:#"Friends facebook ID "]];
[FBRequestConnection startWithGraphPath:[NSString stringWithFormat:#"%#/feed?access_token=%#",userFBID,[appDelegate.mysession accessToken]]
parameters:postTest
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection,
NSDictionary * result,
NSError *error) {
if (error) {
NSLog(#"Error: %#", [error localizedDescription]);
} else {
// Success
}
}];
[postTest release];
