Question

I have one view controller (AViewController) and there I have table.
In that controller I have added another view controller view as a subview (BViewController):

BViewController *barCodeScanner = [[BViewController alloc]init];
[self.view addSubview:barCodeScanner.view];

BViewController has a delegate and one delegate method in it and it works.
But I want to refresh table on AViewController.
So I moved delegate to AViewController and try to change delegate code from:

rdr.readerDelegate = self;

to

rdr.readerDelegate = AViewController;

but it doesn’t work. Why?

Answer 1

You need to create an instance for AViewController and set it as a delegate to rdr:

rdr.readerDelegate = aViewControllerInstance;
