IIViewDeckController

ViewDeck is a framework to manage side menus of all kinds. It supports left and right menus and manages the presentation of the side menus both programmatically and through user gestures.

The heart of ViewDeck is IIViewDeckController, which is a container view controller. You can then assign your center view controller to it as well as side view controllers. IIViewDeckController makes sure your content view controllers are added to the view controller hierarchy their views are added to the view hierarchy when needed.

ViewDeck does not provide any kind of configurable menus. It is up to you to assign your center and side view controllers to ViewDeck so that ViewDeck can then take over and present them as necessary.

IIViewDeckController supports both a left and a right side view controller and of course you can also only use one side. You can open and close the side views programmatically, e.g. through a tap of a button. By default IIViewDeckController also listens to swipe gestures by the user and interactively opens the side views accordingly.

Of course ViewDeck plays nice with existing container view controllers such as UINavigationController or UITabBarController.

Requirements

Base SDK: iOS 10
Deployment Target: iOS 8.0 or greater
Xcode 8.x

Try it out

The easiest way to try out ViewDeck is using cocoapods. By running pod try ViewDeck an Xcode project will be created that runs the demo app. Of course you can also simply check out the repository and run the example app there. Just open the ViewDeckExample.xcworkspace file in the Example folder and run it.

Demo video & Screenshots

You're probably curious how it looks. Here's some shots from the example app:

Installation

CocoaPods

Integrating ViewDeck via CocoaPods is the easiest and fastest way to get started. Simply add the following line into your Podfile:

pod 'ViewDeck'

This will get you the latest ViewDeck version every time you type pod update in your terminal.

If you prefer a more conservative integration, you can also go with the following line:

pod 'ViewDeck', '~> 3.0'

This will update all 3.x version if you execute pod update but it will not update to version 4.x once this is released. ViewDeck follows semantic versioning, meaning that within a given major version (currently 3.x) there will be no breaking changes. You may see deprecations appear on methods that are likely to go away in the next major release but until then they will continue to work.

After integrating ViewDeck via CocoaPods, all you need to do is #import <ViewDeck/ViewDeck.h> in a class where you want to use ViewDeck.

Getting started

ViewDeck supports a left and a right side view controller. Each of these can be nil (if it is, no panning or opening to that side will work and gesture recognizers for this side are deactivated). The base class for everything is IIViewDeckController. A typical view deck configuration looks like this:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
	MyCenterViewController *centerViewController = [MyCenterViewController new];
	UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:centerViewController];
	
	MySideViewController *sideViewController = [MySideViewController new];
	UINavigationController *sideNavigationController = [[UINavigationController alloc] initWithRootViewController:sideViewController];
	
	IIViewDeckController *viewDeckController = [[IIViewDeckController alloc] initWithCenterViewController:navigationController rightViewController:sideNavigationController];
	
	self.window.rootViewController = viewDeckController;
	[self.window makeKeyAndVisible];
	return YES;
}

Switching controllers

You can also switch view controllers in mid flight. Just assign a view controller to the appropriate property and the view deck controller will do the rest:

// prepare view controllers
UIViewController* newController = [[UIViewController alloc] init];
self.viewDeckController.rightController = newController;

You can also use this to remove a side controller by just setting it to nil.

Accessing the view deck controller

Like UINavigationViewController the IIViewDeckController assigns itself to its childviews. You can use the viewDeckController property to get access to the enclosing view deck controller:

#import <ViewDeck/ViewDeck.h>
...
[self.viewDeckController openSide:IIViewDeckSideRight animated:YES];

If the controller is not enclosed by IIViewDeckController, this property returns nil.

Controlling the side’s size

ViewDeck tries to embed into UIKit as nice as possible and therefore leverages a lot of already existing hooks. In order to control a side view controller’s size on the screen, you simply set its preferredContentSize. ViewDeck will respect the width of this size while making sure the height is always the height of the view deck controller itself.

Customizing the side’s appearance and animations

You can customize a lot about how ViewDeck presents side view controllers. Check out the documentation on -[IIViewDeckController animatorForTransitionWithContext:] and IIViewDeckTransitionAnimator.

Special Thanks

Special thanks to Tom Adriaenssen who started this project and created a very great framework that helps so many developers. Sadly he can no longer maintain this framework. Check out his blog if you want to find out why, it’s actually pretty good news, so congratulations, Tom! :)

Very special thanks to the awesome Samo Korosec for designing the beautiful logo for ViewDeck! He is a very great designer and a very funny colleague. If you need cool app design work done, check him out!

Credits

I would appreciate it to mention the use of this code somewhere if you use it in an app. On a website, in an about page, in the app itself, whatever. Or let me know by email or through github. It's nice to know where one's code is used. Also, if you have a cool app that uses view deck, and you want it to be listed here, let me know!
