SWRevealViewController

A UIViewController subclass for revealing a rear (left and/or right) view controller behind a front controller, inspired by the Facebook app, done right!

Features

• A Reveal view controller implemented using view controller containment.
• API easier than a UINavigationController.
• Support for any combination of left/right rear controllers.
• Correct handling of appearance methods on its child controllers that you can rely on.
• Correct handling of rotations.
• Can be embedded as a child view controller of other controllers or deployed as the rootViewController.
• Plays nicely with any child view controllers or parent controllers.
• Can be deployed as a child of itself to create cascade-like, hierarchical interfaces.
• Seamless integration of pan gesture recognizer, behaving as smooth as silk.
• A category method on UIViewController, revealViewController, to get the parent SWRevealViewController of any child controller, similar to the UIViewController's property navigationController.
• Lightweight, clean, easy-to-read, self-documenting code that you will enjoy using in your projects.

Examples

Requirements

• iOS 5.1 or later.
• ARC memory management.

Usage

SWRevealViewController can either be installed in your project using CocoaPods or by copying the following to your project:

• SWRevealViewController.h

• SWRevealViewController.m

• Initialize an instance of a SWRevealViewController passing in a "rear" and a "front" view controllers.

• Use the SWRevealViewController instance in your code as you would use any view controller.

• Deploy as the application window rootViewController, or as a child of other containment controllers.

• Add the panGestureRecognized provided by the SWRevealViewController to a suitable view of your "front" view controller, for example use the viewDidLoad method of your controller to add the gesture recognizer to a navigationBar.

• At any time, you can reveal, conceal the "rear" view or replace the "front" view controller, programmatically or based on user actions, with or without animations enabled

Basic API Description

Initializing a SWRevealViewController:

- (id)initWithRearViewController:(UIViewController *)rearViewController frontViewController:(UIViewController *)frontViewController;

Setting the right view controller:

@property (strong, nonatomic) UIViewController *rightViewController;

Animated setting of the front view controller:

- (void)setFrontViewController:(UIViewController *)frontViewController animated:(BOOL)animated;

Animating the position of the front view controller. Position can be: FrontViewPositionLeftSideMostRemoved, FrontViewPositionLeftSideMost, FrontViewPositionLeftSide, FrontViewPositionLeft, FrontViewPositionRight, FrontViewPositionRightMost or FrontViewPositionRightMostRemoved

- (void)setFrontViewPosition:(FrontViewPosition)frontViewPosition animated:(BOOL)animated;

Obtaining a gesture recognizer to add to your front view controller:

- (UIPanGestureRecognizer*)panGestureRecognizer;

Other methods are documented in the SWRevealViewController.h header file.

Release Notes (Including iOS 7 Compatibility Status)

Version 1.0.5 (August 30th)

• Added enhanced support for iOS7 (beta 6) by automatically adjusting insets of child controllers which main view is a UIScrollView -such as UITableViewController-. This seems to contradict the iOS7 transition guidelines because child controllers are supposed to deal with their own layout and offsets, however this is consistent with what a UINavigatorController does when it contains a UITableViewController. Now the SWRevealViewController attempts to mimic the behavior of a UINavigationController on this.

• Added a new property presentFrontViewHierarchically. You can set it to YES on iOS7 when you add a SWRevealViewController as a child of a UINavigationController (or another SWRevealViewController) and you want the front view controller to be presented below the navigation bar of its UINavigationController grand parent. The rearViewController will still appear full size and blurred behind the navigation bar of its UINavigationController grand parent.

Previous Notes

• As of July 19th, 2013, the SWRevealViewController has been tested on iOS 7 beta 3.
• The SWRevealViewController now works fine on iOS 7 with Apple-provided child view controllers such as UINavigationController.
• The RevealControllerExample and RevealControllerExample2 examples have been updated to use UINavigationControllers instead of a navigation bar on top of a view. Thus, all child view controller layouts are now correctly handled by the Apple implemented of the UINavigationController.
• According to Apple, iOS 7 transition guidelines, developers are responsible for managing the required view offsets and bar height extensions on custom view controllers depending on the version of iOS. RevealControllerExample3 has not yet been updated to take iOS 7 layouts and the new status bar into account, so it still defaults to the iOS 6 layout.
