You have a UITableViewController with a couple of static cells, you want to invoke some code for each cell in the delegate. Here's a quick way to do it:

    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {
        
        SEL action = (SEL[]){@selector(method1), @selector(method2)}[indexPath.row];
        ((void (*)(id, SEL))[self methodForSelector: action])(self, action);
    }

It's got everything you love about C and Objective-C: array literals, function pointers, casting, selectors and something called IMPs.

This piece of code maps selected cells to methods by putting methods by indexing selectors in a C array.

Why all the fuss on the second line? wouldn't a simple performSelector: work? The short answer is: to show the compiler that we are responsible adults. You can read more about it [here](SO Answer);
