Question

when u first open up iphone, all the app are layout in a “grid icon” type. And if u have too many app, the user swipe to the right, and the new view come out, with again all the app appear in a “grid icon” layout. Can u guys point me to where I can achieve such a design. Code would be very appreciated !!!
I did try something and here is what I got so far.
In my delegate.h class I have

UITabBarController *tabBarController;
View1 *view1; //Inherit from UIViewController
View2 *view2; //Inherit from UIViewController

In my delegate.m class I have

- (void)applicationDidFinishLaunching:(UIApplication *)application {    

    tabBarController = [[UITabBarController alloc] init]; //Create a tab bar
    view1 = [[View1 alloc] init]; //Create the first view
    UINavigationController *navigationController1 = [[UINavigationController alloc] initWithRootViewController:view1];

    view2 = [[View2 alloc] init]; //create the second view
    UINavigationController *navigationController2 = [[UINavigationController alloc] initWithRootViewController:view2];

    tabBarController.viewControllers = [NSArray arrayWithObjects:navigationController1, navigationController2, nil];

    [window addSubview:tabBarController.view];
    [window makeKeyAndVisible];
 }

So now I have two tab that load view1 and view2, they both implement UINavigationController, meaning that if I create another view3, when I pushViewController, I can create the animated effect like the iPhone. Then in view3.m when I try to go back, I can popViewController. However what I cant achieve is, let see that each view I will have 4 icon, so when I query back from the db, I know I have to display 12 icon, meaning 3 views. But I only know what information at runtime 🙁 . As it is right, I do actually have view1, view2 and view3 as view1.m, view2.m and view3.m. If the number of icon go above 12, meaning I need another view then I am screw. Help please

Lots of the solution here seems to be overkilled. Here is how I do it. Create a UIViewControllerTemplate, that contain 4 (or more) customize buttons on it. So every time you create a new view, you will have a layout that will look like ‘grid’

-(void) initButtons{
    //button size 100 X 100
    int shiftx = -5;
    int shifty = 15;
    (self.button1).frame  = CGRectMake(40-shiftx, 50-shifty, 100, 100);
    (self.button2).frame  = CGRectMake(180-shiftx, 50-shifty, 100, 100);
    (self.button3).frame  = CGRectMake(40-shiftx, 250-shifty, 100, 100);
    (self.button4).frame  = CGRectMake(180-shiftx, 250-shifty, 100, 100);
}

-(void) viewDidLoad{
    [self initButtons];
    [self.view addSubView:self.button1];
    [self.view addSubView:self.button2];
    [self.view addSubView:self.button3];
    [self.view addSubView:self.button4];
    [super viewDidLoad];
}
