ios - TableView not reloading

Question

I am designing a one-to-one chatting interface using table view. This table view is modified to show bubbles as some new message arrives. The new message arrives through a push-notification in this case. I call following code in my function which receives message through the push notification:

-(void)messageReceived: (NSString *)message{
    _message=[message retain];
    [tableView reloadData];
}

However, it seems this does not reload my table view. If I place the call for reloadData in the viewDidAppear function, it reloads fine. It also reloads fine, if I place the reloadData call in a function whose return type is IBAction (ex: a function binding to button click)

What could be the reason for reloadData to not get triggered through custom declared functions ?

Answer 1

reloaddata method is called but the trick here that you didn't add the incoming message to the datasource that the tableview load from !
