I’m sure this a very nooby question, but I can’t figure it out. I have a UITextField *numberOfPointsTextBox which allows my users to input an integer. I want this value to be the number of rows in the UITableView *myTableView which is in the same view as the numberOfPointsTextBox. I also want the user to be able to change this value and have the number of cells update accordingly. The only solution that I have been able to find is to create a “for” loop which would create an NSIndexPath for each, but there must be a better solution out there. Any ideas? Thanks in advance!

    The number of rows the UITableView displays is controlled through UITableViewDataSource‘s tableView:numberOfRowsInSection: method. Your code should listen to changes of UITextField *numberOfPointsTextBox, update the number of points in your custom instance of the UITableViewDataSource with which you have configured your UITableView, and finally call reloadData on the UITableView to complete the update.
