iPhone app - adding another view - ios

Question

I am working on an iPhone app but found that I require another view / window to get the user to input and save data / information there.
How do I add another view? Do I add it in interface builder and then link it in the main app delegate or will it have its own .h and .m files.
I selected a window view app to start with, do I need to start over with a flip side view app or can this just be added in anyway if I have the correct code there.
manny thanks

The Window app is perfect for you. In your AppDelegate file, you should have a section like this:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
//instantiate the venue view controller object
YourViewController *yourViewController = [[YourViewController alloc] initWithNibName:#"YourView" bundle:[NSBundle mainBundle]];
// Configure and show the window
[window addSubview:[yourViewController view]];
[window makeKeyAndVisible];
}
This is the part of the code that declares, allocates and adds your custom view to the window. You have a couple choices for how to add the second view. You can either add it in place of this one, or add it after this one using a Navigation Controller. To add the navigation controller, change the above method to look like this:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
//instantiate the venue view controller object
YourViewController *yourViewController = [[YourViewController alloc] initWithNibName:#"YourView" bundle:[NSBundle mainBundle]];
UINavigationController *yourViewControllerWrapper = [[UINavigationController alloc] initWithRootViewController: yourViewController];
// Configure and show the window
[window addSubview:[yourViewControllerWrapper view]];
[window makeKeyAndVisible];
}
There, we create your custom view, then wrap it in a navigation controller. The navigation controller is what gets added to the window. Next the code to switch to the second view would look like this, assuming you switch views on a button press:
-(IBAction)switchViewController{
MySecondViewController *secondViewController = [[MySecondViewController alloc] init];
[self.navigationController pushViewController:secondViewController];
}
Of course, you should replace the line
MySecondViewController *secondViewController = [[MySecondViewController alloc] init];
with the proper way of instantiating your second view controller. This could be from a nib file like above, or programmatically.
As far as creating the view files, you should create a nib in Interface builder for the layout of everything, then create a .h and .m file for the ViewController code itself.

you can also display new frame instead of new view. It is easier sometimes, as you don;t have to pass parameters - you are in one class:
CGRect frame = okresView.frame;
frame.origin.x = frame.size.width;
if ( [okresView superview] == nil )
{
[self.view addSubview:okresView];
}
okresView.frame = frame;
[okresDataTableView reloadData]; // przeładowanie tabeli na subwidoku
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:.5];
frame.origin.x = 0;
okresView.frame = frame;
[UIView commitAnimations];
if you want new subview, you can use a few methods - just download few applications from XCode help and check how they do this. Nice example are in 'Elements' and 'UICatalog' application where you have flipped view and other examples.
// Create and push another view controller.
UIViewController *myViewController = [[UIViewController alloc] init];
myViewController.title = #"My First View";
myViewController.view.backgroundColor = [UIColor redColor];
//to push the UIView.
[self.navigationController pushViewController:myViewController animated:YES];
