didSelectRowAtIndexPath: not being called

Question

I have a UITableView as a subview of my UIScrollVIew, which is the main view controlled by my MainViewController.

In MainView

Answer 1

I had intermittent failure of didSelectRowAtIndexPath: being called on my custom cell press.

I discovered that if I stopped calling [tableView reloadData] very often (10 Hz), and changed it to update every 2 seconds, almost every press would successfully call didSelectRowAtIndexPath:

It seems like reloading the view blocks presses.
