Question

I have an application in which i am using a sidemenu controller like a facebook app.its basically a UITableViewController.when i am using [self.tableView reloaddata] in the view will appear methode for the first time its working fine.Because of some requirement i need to reload this table view from another view controller.so i did this:

 SideMenuViewController *second = [[SideMenuViewController alloc]init];
 [second viewWillappear:YES]

where i am reloading the data.But when i am doing this the reloaddata is not calling the cellforindexmethode of the tableviewcontroller But it is calling the numberOfRowsInSection methode.Can anybody help me in finding where i am going wrong.

You could use a notification to to this.

In the SideMenuViewController viewDidLoad method you add a this:

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(reloadTable)
                                             name:@"SideMenuShouldRefreshDataNotification"
                                           object:nil];

The reloadTable method looks like this:

-(void)reloadTable {
dispatch_async(dispatch_get_main_queue(),^{
  [self.tableView reloadData];
});
}

When you want to refresh the table you just post this notification from anywhere you want in your app.

[[NSNotificationCenter defaultCenter] postNotificationName:[NSNotification notificationWithName:@"SideMenuShouldRefreshDataNotification" object:nil]];
