ICSDrawerController is a left-side drawer controller for iPhone (iOS 7 or later).

It has all the features you'd expect from a side drawer controller, plus it's small, easy to read and tailor to your needs.

The controller is designed as a container controller and accepts two child controllers: the left and the center view controllers. The left view controller is intended as a master view controller: it is visible only when the drawer is open and, typically, talks to the drawer in order to update/replace the center view controller. The center view controller is intended as a detail view controller: it is visible when the drawer is closed and typically sends the open message to the drawer to reveal the left side controller.

ICSDrawerController uses a UIPanGestureRecognizer to open/close the drawer and a UITapGestureRecognizer to close the drawer by tapping anywhere on the visible part of the center view controller.

It is left to your center view controller to provide a button and call open on the drawer controller. (From your child controllers you access the drawer controller by adopting the ICSDrawerControllerChild protocol and implementing the required drawer property.)

You can control the status bar's visibility and style by implementing, in each one of your child controllers, the prefersStatusBarHidden and preferredStatusBarStyle methods made available by iOS 7.

The drawer controller will notify its child controllers by sending:

• the message drawerControllerWillOpen: when the drawer is about to open
• the message drawerControllerDidOpen: when the drawer has completed the opening phase
• the message drawerControllerWillClose: when the drawer is about to close
• the message drawerControllerDidClose: when the drawer has completed the closing phase

1. Drag the inner ICSDrawerController folder to your Xcode project
2. Adopt in your child controllers the ICSDrawerControllerChild protocol and implement its the required drawer property
3. Adopt in your child controllers the ICSDrawerControllerPresenting protocol
4. Initialize the drawer controller with your left view controller and your initial center view controller:

YourLeftViewController *left = [[YourLeftViewController alloc] init];
YourCenterViewController *center = [[YourCenterViewController alloc] init];
ICSDrawerController *drawer = [[ICSDrawerController alloc] initWithLeftViewController:left
                                                                 centerViewController:center];

For a concrete example on how to use this controller, have a look at the provided Colors project.
