Would that be self.tableView because you created the thing inside another thing?

 

[Kapthehat]

Thanks. Are you suggesting something along the lines of:-

UITableView *tableView = (id)[self.view viewWithTag:1];
  [self.tableView registerClass:[BIDNameAndColorCell class];

as I tried that and it didnt work.

Warning or error?

That code should work just fine. Email me the project so I can take a quick look.

No it wouldn't.

    UITableView [COLOR="DarkOrange"]*tableView[/COLOR] = (id)[self.view viewWithTag:1];
    [[COLOR="DarkOrange"]tableView[/COLOR] registerClass:[GraphViewController class] forCellReuseIdentifier:@"Cell"];

With the above code - the second line is referencing the UITableView *tableView above it.

Using self.tableView would mean there was a

@property(strong, nonatomic)IBOutlet UITableViewController *tableView

declaration in the header or class extension part of the implementation file.

That's my understanding of it anyway.

 

[Tander]

Replace your code with this:

    UITableView *tableView = (id)[self.view viewWithTag:1];
         [tableView registerClass:[BIDNameAndColorCell class] forCellReuseIdentifier:CellTableIdentifier];

Let me know if that solves it.

The method signature must match exactly or it is a different method. And, joy of joys, C, Objective C, and C++ are all case-senstive. This bites me sometimes too. (C is case sensitive but I'm not case sensitive.)

You are trying to call:

-[registerClass:forCellReUseIdentifier:]

The correct method name is

-[registerClass:forCellReuseIdentifier:]

(You have an incorrect
upper case "U". "forCellReUseIdentifier" should be "forCellReuseIdentifier")
