Question

My app has four tabs. The root view controller of the first tab (index zero) is where the log in page pops up as a modalviewcontroller, but a view controller in the fourth tab (index three) is where the log out button is. Is there a way to programmatically set it so that when the logout button is pushed the app transitions to the tab at index zero? I initially tried a push transition, but that made the root view controller of index zero instead show up as a view controller in index three.

Answer 1

If you want to programmatically change the tab, just call

[self.tabBarController setSelectedIndex:index];

In your case create the selector, which will be assigned to the logout button event.

- (IBAction) didClickLogoutButton:(id)sender {
    // do some work to log out the user...
    [self.tabBarController setSelectedIndex:0];
}

Hope this is what you meant.
