Question

I want to post something on the user wall. I used the below code to post on the user wall but I’m getting a blank screen as soon as I log in. Can anyone help out?

(void) fbDidLogin {

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
[defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
[defaults synchronize];

NSString *kAppId;
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               kAppId, @"109133762519851",
                               @"http://developers.facebook.com/docs/reference/dialogs/", @"link",
                               @"http://fbrell.com/f8.jpg", @"picture",
                               @"Facebook Dialogs", @"name",
                               @"Reference Documentation", @"caption",
                               @"Dialogs provide a simple, consistent interface for apps to interact with users.", @"description",
                               @"Facebook Dialogs are so easy!",  @"message",
                               nil];

[facebook dialog:@"feed" andParams:params  andDelegate:self];
