Question

I’m wondering how this:

could be done programmatically? Is it just setting the uitableview datasource and delegate to the FadingTableView class? What exactly is going on by setting the custom class in IB?

Thanks.

Answer 1

Here you are telling IB that the table view instance is actually the instance of FadingTableView.
and if you want to create this table view programmatically then use these line

FadingTableView *tableView = [[FadingTableView alloc] init.....];

Why you set that class in IB is because the IB has inbuilt objects thus UITableView but you want your table view which is not present in the IB thus you put your class name there so that it will create instace of FadingTableView instead of UITableView.
And No it’s not used for connecting datasource or delegate.
