How to add a selected UITableViewController value to a previous UITableViewController?

Question

User clicks on "Remote" button and then the following UITableViewController loads up:

The user then selects any value upon which I call:

[self.navigationController popViewControllerAnimated:YES];

to go back again to the previous UITableViewController (screen shot 1).

How do I add the selected value to the UITableViewController?

I hope I am making sense.

Answer 1

In your remote recipients table view controller , you have the Array with which you are loading the table (say myTestArray ). Keep it as a property. And also have a NSInteger property (say selectedRow ) which will identify which row user selected. And when you go back to the add recipient table view controller , you can know which row was selected by

[remoteRecipientsController.myTestArray objectAtIndex:remoteRecipientsController.selectedRow];

Or use delegates. Upon row selection the remote recipients will give a call back telling which row was selected.

Update: If you dont have access to the view controller, use delegates.

You can get both array and the selected row in the delegate method, something as follows:

-(void) remoteRecipient:(RemoteRecipientController *) remoteRecipientController didSelectRow:(NSInteger) row {
// Get the selected row
... = [remoteRecipientController.myTestArray objectAtIndex:row ];
}

Or you can also configure the delegate to just return the selected row (as your string), something as follows:

-(void) remoteRecipient:(RemoteRecipientController *) remoteRecipientController didSelectRow:(NSString *) selectedRecipient {

}

Ofcourse, In this case you need to make remote recipient controller pass the selected row as NSString in the delegate.
