Adding a Tab Bar Object

matthew858 · Dec 14, 2008

I was looking at adding a tab bar object to TheElements sample code, but was wondering how to do it. I am trying to make a tab bar object called "First", so I made some .h and .m files called "FirstTabController". A added the header file to TheElementsAppDelegate, and I declared it in TheElementsAppDelegate.m the following way:

Quote

localNavigationController = [self createNavigationControllerWrappingViewControllerForDataSourceOfClass:[FirstTabController class]];
[localViewControllersArray addObject:localNavigationController];

[localNavigationController release];

Firstly, is this implementation all right?

In FirstTabController, I put the following code:

Quote

#import "FirstTabController.h"
#import "TheElementsAppDelegate.h"

@implementation FirstTabController;

- (NSString *)name {
return @"First";
}

- (NSString *)navigationBarName {
return @"First";
}

- (BOOL)showDisclosureIcon
{
return NO;
}
- (UIImage *)tabBarImage {
return [UIImage imageNamed"first.png"];
}
@end
Click to expand...

What else do I have to do in order to get my tab to display and just display a blank view?

Thanks in advance!

OK, I have established that I need the following code in TheElementsAppDelegate.m if I want to show an empty view:

Quote

UIViewController * viewController = nil;
viewController = [[UIViewController alloc] init];

UIView * view = nil;
view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

viewController.view = view;
[view release];

UINavigationController * navigationController = nil;
navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
[viewController release];

[localViewControllersArray addObject:navigationController];
[navigationController release];
Click to expand...

How can I implement this into a view controller subclass?
