Question

In my iphone app i want to post photos to selected facebook contacts. I'm getting that photos from phone library.
I'm using this code:
fbString=[NSString stringWithFormat:#"%#\n%#",appdelegate.titleString,appdelegate.descriptionString];
NSArray *permissions =[NSArray arrayWithObjects:#"publish_actions",#"publish_stream",#"manage_friendlists", nil];
NSData* imageData = UIImageJPEGRepresentation(self.img, 90);
NSLog(#"imageData %#",imageData);
NSMutableDictionary *params = [[NSMutableDictionary alloc] initWithObjectsAndKeys:fbString, #"message",imageData,#"source",nil];
NSLog(#"fbid count %d",fbidarray.count);
[[FBSession activeSession] reauthorizeWithPublishPermissions:permissions
defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session, NSError *error)
{
if (!error) {
for(int j=0;j<fbidarray.count;j++)
{
[FBRequestConnection startWithGraphPath:[NSString stringWithFormat:#"%#/photos",[fbidarray objectAtIndex:j]] parameters:params HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error1)
{
NSLog(#"errors in the view %#",error1);
if(!error1 )
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Success"
message:[NSString stringWithFormat:#" Sucessfully posted "]
delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
}
}];
}
}
}];

You can try this :
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) {
[self hideHUD];
NSLog(#"Error: %#", [error localizedDescription]);
} else {
// Success
}
}];
[postTest release];
