iPhone Modal View Smaller that the screen

Question

I\'m trying to do something that shouldn\'t be that complicated, but I can\'t figure it out. I have a UIViewController displaying a UITableView. I want to present a context menu

Answer 1

What I did was create a UIViewController on top of my UINavigation controller in my app delegate and made it a property of a singleton object for convenience:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

//--- create root navigation controller
self.window.rootViewController = self.navigationController;

//--- create view controller for popups:
popupViewController = [[BaseViewController alloc] init];
popupViewController.view.backgroundColor = [UIColor clearColor];
popupViewController.view.hidden = true; //for rendering optimisation
[self.window addSubview:popupViewController.view];
[AppState sharedInstance].popupViewController = self.popupViewController;

//--- make all visible:
[self.window makeKeyAndVisible];

return YES;

}

At any point in my app, I can then call e.g.

MyViewController * myVC = [[UIViewController alloc] init];
//... set up viewcontroller and its view...
// add the view of the created view controller to the popup view:
[AppState sharedInstance].popupViewController.view.hidden = false;
[[AppState sharedInstance].popupViewController.view addSubview:myVC.view];

The BaseViewController used on the top just inherits from UIViewController and sets up a full-screen view:

//----- in BaseViewController implementation
- (void)loadView {
   //------- create root view:
   CGRect frame = [[AppState sharedInstance] getScreenFrame]; 
   rootView = [[VCView alloc] initWithFrame:frame];
   rootView.backgroundColor = [UIColor whiteColor];
   self.view = rootView;
}
