How to renew view on tab in tab bar controller

Question

I have UITabBarController with two tabs. Each tabs have UITableViewController which view data from database.

When I change data and switch tab view doesn't change. When I back and switch tab again, view is ok!

How can I renew view programmatically?

Have you tried calling `reloadData` in `viewWillAppear:`? – Matthias Bauch Jan 12 '15 at 13:00 — Matthias Bauch, Jan 12 '15 at 13:00

You need to call <tableview>.reloadData(). That will tell the table view to get the new count and fetch the displayed rows once again.

In what place should I do it? I change data in one tab and see to another. – Walter West Jan 12 '15 at 14:56
In the place where you modify the data itself. Where "When I change data" happens. – qwerty_so Jan 12 '15 at 18:18

Need to fetch data in viewWillAppear, don't in viewDidLoad. Thank you Matthias Bauch!
