GDSheetController

GDSheetController is a controller to organize multiple controllers or navigation controllers in a stack of sheets inspired by Evernote Food 2.0 app.

Note: If GDSheetController provide a better user experience in portrait it will be usable in landscape later.

Features

• Present your controllers in a stack of sheets,
• Dynamically add or remove sheets at runtime,
• Use preview controller to preview your sheets when they are presented as a stack.
• In Evernote Food 2.0 they preview with a picture when their embedded controller contains content,
• Sometimes your controller as a sheet does not look as good as in fullscreen.
• Integrate GDSheetController as:
• a root controller of your window,
• a child view controller in your controllers hierarchy,
• a subclass because you need to interact with content above your sheet controller.

Installation

Installation may be as simple as using it ;-)

###CocoaPods If you are using CocoaPods

1. Simply add pod 'GDSheetController', '~> 0.1.1' to your podfile
2. And then run

• pod update if you already have a project with pods
• pod install to integrate your pods to your project

To know more about CocoaPods and usage, visit their website.

###Manual install

1. Download the ZIP from Github and copy the GDSheetController directory to your project
2. Link the QuartzCore.framework and CoreGraphics.framework libraries in your project's Build Phases
3. #import "GDSheetController.h" and enjoy :-)

###Support and tested environments This component was designed and tested for iOS 6 and iOS 7 but may be compatible with iOS 5. No tests has been made on this platform through.

Usage

###As a root controller (DEMO_MODE_ASROOT)

You may need to use GDSheetController as a root view controller when this is the entry point of your application.

####Example in your appDelegate

NSArray *arrayOfControllers = @[vc1, vc2, vc3];
GDSheetController *sheetC = [GDSheetController sheetControllerWithControllers:arrayOfControllers
                                                                      options:nil];
self.window.rootViewController = sheetC;

###As a child controller (DEMO_MODE_EMBEDDED)

Use GDSheetController as a child view controller when you need to display it in a navigation controller for example.

####Example

//Same initialization as root usage
NSArray *arrayOfControllers = @[vc1, vc2, vc3];
[GDSheetController sheetControllerWithControllers:arrayOfControllers
                                          options:nil];

###As a subclass (DEMO_MODE_DYNAMIC)

Use GDSheetController as a subclass when you need to provide some controls above your sheets at the same level.

####Steps

1. Subclass GDSheetController: @interface MyAwesomeController : GDSheetController
2. Add #import "GDSheetController_subclass.h" in your implementation file.
3. Call in your viewDidLoad method

//Options here, provide you a top extra space of 70 points to put your widgets
NSArray *arrayOfControllers = @[vc1, vc2, vc3];
[self setEmbeddedControllers:arrayOfControllers
                 withOptions:@{GDSheetControllerSheetsStartFromTopKey:@(70)}];

###Options and personalization A lot of options are available in GDSheetController.h and can be passed in options dictionary at init.

Example:

/**
 * Determines the UIPanGestureRecognizer and UITapGestureRecognizer scope over the sheet.
 *
 * When using GDSheetGestureScope_NavBar the gestures are available only on the
 * navigation bar if your controller is embedded in a navigation controller.
 * Overwise GDSheetGestureScope_All is performed.
 *
 * @default GDSheetGestureScope_AllButTap
 * @value NSNumber containing a GDSheetGestureScope value
 */
extern NSString * const GDSheetControllerSheetGestureScopeKey;

NSArray *arrayOfControllers = @[vc1, vc2, vc3];
NSDictionary *options       = @{GDSheetControllerSheetGestureScopeKey:@(GDSheetGestureScope_All)}

[GDSheetController sheetControllerWithControllers:arrayOfControllers
										  options:options];

Screens

###Distance between sheets You can customize spaces between sheets but GDSheetController automatically adapts its layout for displaying all your sheets on screen. That is why you define a maximum space between your sheets using GDSheetControllerMaxDistanceBetweenSheetsKey.

/**
 * Determines the max distance between sheets to show embedded controller
 * content when sheets are closed
 *
 * @default 70.f
 * @value NSNumber containing CGFloat
 */
extern NSString * const GDSheetControllerMaxDistanceBetweenSheetsKey;

###Managing fullscreen when using as a child ViewController When GDSheetController is embedded in a UINavigationController or if your are using it as a custom child UIViewController you can experience some issues with Fullscreen sheets. That is why GDSheetController propose a fullscreen mode via the GDSheetControllerSheetFullscreenModeKey option.

You can choose:

• GDSheetFullscreenMode_Controller
• Sheet go fullscreen inside the sheet controller only! (by default)
• GDSheetFullscreenMode_Screen
• Sheet go fullscreen on the whole screen (following current keyWindow) and go outside the sheet controller

Then your controllers will pass above the existing UINavigationBar of the UINavigationController embedding your GDSheetController.

Known Issues

• FIXED iOS7 support
• Handling orientation changes correctly
• Still having an issue when moving from landscape right to landscape left.
• Fullscreen controllers won't go landscape
• When using GDSheetFullscreenMode_Screen back to default animation does NOT run smoothly.
• Make an iPad demo

This component is highly inspired from KLNoteViewController by Kieran Lafferty. Thanks to him.

Got some ideas from PKRevealController too, thanks to Philip Kluz.
