    <p>To get the controller, just: </p> <pre><code>[[tabBarController viewControllers] objectAtIndex:indexOfTheTab] </code></pre> <p><code>tabBarController</code> refers to <code>UITabBarController *tabBarController</code> in you AppDelegate.</p> <p>EDIT 1: add this to your AppDelegate.h</p> <pre><code>-(UITabBarController*)getTabBarController; </code></pre> <p>add this to your AppDelegate.m</p> <pre><code>-(UITabBarController*)getTabBarController { return tabBarController; } </code></pre> <p>Now, you can access it from everywhere:</p> <pre><code>[(AppDelegate*)[[UIApplication sharedApplication] delegate] getTabBarController] </code></pre> <p>Don't forget <code>#import "AppDelegate.h"</code></p> <p>EDIT 2: In you AppDelegate.m</p> <p>In the first method, just add: <code>self.tabBarController.delegate = self;</code></p> <p>Then, override:</p> <pre><code>- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { //something like : [tabBarController hideTheStuffs]; } </code></pre> <p>With EDIT 2 you can listen to the user touches in the tab bar, even if the tab item is already the current one. With EDIT 1 you can access your delegate from everywhere if needed.</p> <p>EDIT 3:</p> <p>Do you have a <code>IBOutlet UIWebView *myWebView</code> in you ControllerView.h (the one with the view that shows the web view). If not, add this outlet, then connect it to your webview in interface builder.</p> <p>In the controller, add a method in .h and .m :</p> <p><code>-(void)hideTheWebView { myWebView.hidden = YES; }</code></p> <p>As this method is declared in the interface (.h), you can call it from the AppDelegate, method tabBarController:didSelectViewController.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
