I added this code to SHKSharer.m. I think this can be useful to some of the users (like me)
+(BOOL)isServiceAuthorized
{
SHKSharer *controller = [[self alloc] init];
BOOL isAuthorized = [controller isAuthorized];
[controller release];
}
+(void)promptAuthorization
{
SHKSharer *controller = [[self alloc] init];
[controller promptAuthorization];
[controller release];
}
