I get StandardError: Permissions error .. But the user is in my database :(.Why do i get this? how can i make it function?

Perhaps the user has yet to authorize your application, or has since removed the application. By "the user is in my database" do you mean you've stored the UID? -- Pete (563683308 12:42, 9 January 2009 (PST))

[edit] ability to check more than one permission.

Hi. If Facebook are considering updates to the platform, it would be good if the api/php client would accept an array of multiple permissions as well as a single string permission. 721599476 17:19, 6 April 2009 (PDT)

[edit] Error(104) Incorrect signature

Hi, I always have this error. I'm an iPhone developper. Here is my code:

- (void)userHasAppPermission
{
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: _uid, @"uid", nil];
[[FBRequest requestWithDelegate:self] call:@"facebook.Users.hasAppPermission" params:params];
}

What the problem? The _uid variable is a NSString containing my own uid number.
