sometimes you just want to put things on top of things

An Objective-C / Cocoa Touch class for managing a vertical "stack" of UIViews and UIViewControllers in the Z-dimension. This is a useful alternative to adding additional UIWindows to an application or having an unorganized approach to adding subviews to the main UIWindow. The Z-position of views can be specified to let you arrange which views are in front of others.

DRWindowController takes care of everything under the hood for adding UIViewControllers by calling addChildViewController: and addSubView: for you.

Installation with CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like AFNetworking in your projects. See the "Getting Started" guide for more information.

pod 'DRWindowController', '~> 1.0.3'

Show me what this magic is!

Setting your root view controller

The easiest way to use this library is to set your app's rootViewController to be your own custom subclass of DRWindowController. Then, it is very simple to add new view controllers or views. You probably want to add your app's main controller in AppDidFinishLaunching.

DRWindowController *windowController = [[DRWindowController alloc] initWithNibName:nil bundle:nil];
self.window.rootViewController = windowController;
[self.window makeKeyAndVisible];

// Add root controller to window manager
UIViewController *mainViewController = /* your main controller */
[windowController addWindowController:familyController atIndex:1];

Adding custom UI above main UI

// add newcontroller to window controller
UIViewController *partialScreenModalController = /* whatever */
[windowController addWindowController:partialScreenModalController atIndex:2 withCompletion:nil];


// add new UIView to the window
UIView *customAlertView = /* as you will */
[windowController addWindowView:customAlertView atIndex:100];

Interface

typedef void (^DRWindowCompletionBlock)();

@interface DRWindowController : UIViewController

// Adding new views
- (void)addWindowView:(UIView *)view atIndex:(NSInteger)index;
- (void)addWindowController:(UIViewController *)controller atIndex:(NSInteger)index;
- (void)addWindowController:(UIViewController *)controller atIndex:(NSInteger)index withCompletion:(DRWindowCompletionBlock)handler options:(NSInteger)options; // todo:make a typedef
- (void)addWindowController:(UIViewController *)controller atIndex:(NSInteger)index withCompletion:(DRWindowCompletionBlock)handler;

// Removing views
- (void)removeWindowView:(UIView *)view;
- (void)removeWindowController:(UIViewController *)controller;
- (void)removeAllControllers;
