    <p>I've been online for about an hour now trying to find different ways to set custom images i have onto my tab bar. I am using a resizing class. it's <code>UIImage+ProportionalFill</code> if anyone is familiar with it. I am a bit new to Objective-C and I have little knowledge on using <code>AppDelegate.h</code> here is my code. feel free to rip me a new one because I'm sure its probably going to be a rookie mistake.</p> <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions { // [UIApplication sharedApplication].idleTimerDisabled = YES; [application setStatusBarStyle:UIStatusBarStyleBlackOpaque]; [[UITabBar appearance] setBackgroundColor:[UIColor colorWithRed:0/255.0 green:255/255.0 blue:255/255.0 alpha:1.0]]; UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController; UITabBar *tabBar = tabBarController.tabBar; UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0]; UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1]; UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2]; UITabBarItem *tabBarItem4 = [tabBar.items objectAtIndex:3]; UITabBarItem *tabBarItem5 = [tabBar.items objectAtIndex:4]; UIImage *oldProfile= [UIImage imageNamed:@"profile.png"]; UIImage *oldFeed = [UIImage imageNamed:@"feed.png"]; UIImage *oldSearch = [UIImage imageNamed:@"search.png"]; UIImage *oldNotifications = [UIImage imageNamed:@"notification.png"]; UIImage *oldMap = [UIImage imageNamed:@"compass.png"]; UIImage *newProfile; UIImage *newFeed; UIImage *newSearch; UIImage *newNotifications; UIImage *newMap; CGSize newSize = CGSizeMake(30, 30); newProfile = [oldProfile imageScaledToFitSize:newSize]; newFeed = [oldFeed imageScaledToFitSize:newSize]; newSearch = [oldSearch imageScaledToFitSize:newSize]; newNotifications = [oldNotifications imageScaledToFitSize:newSize]; newMap = [oldMap imageScaledToFitSize:newSize]; [tabBarItem1 setFinishedSelectedImage:newFeed withFinishedUnselectedImage:newFeed]; [tabBarItem2 setFinishedSelectedImage:newMap withFinishedUnselectedImage:newMap]; [tabBarItem3 setFinishedSelectedImage:newSearch withFinishedUnselectedImage:newSearch]; [tabBarItem4 setFinishedSelectedImage:newNotifications withFinishedUnselectedImage:newNotifications]; [tabBarItem5 setFinishedSelectedImage:newProfile withFinishedUnselectedImage:newProfile]; // Override point for customization after application launch. UIApplication* app = [UIApplication sharedApplication]; app.networkActivityIndicatorVisible = YES; return YES; } </code></pre> <p><em>EDIT</em> the error I receive is: </p> <pre><code> -[UINavigationController tabBar]: unrecognized selector sent to instance *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '- [UINavigationController tabBar]: unrecognized selector sent to instance ` </code></pre>

    1. COSo what's the problem? What result does this code give you? The UITabBarController class reference states that, "tab bar items are configured through their corresponding view controller" -- so you shouldn't be doing this in the app delegate, each controller should provide its own tab bar item.

    3. CODo you not understand that error? It's telling you that what you think is a tab bar controller (self.window.rootViewController) is actually a navigation controller.

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.

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