DropdownMenu is a navigation controller for setting the view of a ContainerViewController using a dropdown menu (aptly named, no?). Dropdown menus are in many situations superior to the more commonly used slide menu, and can also be a good alternative to tabs when you want to reduce visual distractions yet make less often used functions easily discoverable. This implementation is inspired by the menus used in the iOS7 apps from DropBox and Vine. It's built with storyboard, segues and modern APIs and hence requires iOS6+. The project was adapted from Martin Hartl's MHCustomTabBarController which in turn has lineage from Matthijs Hollemans' MHTabBarController. Without their prior contributions this would have taken me a lot longer, so thanks guys!
The easiest is to look at the supplied example, and hook up your ViewController the same way. The project relies on a UIViewController of the class 'DropdownMenuController', which needs to contain two UIViews, the 'menuBar' and the 'menu' itself — in addition to the Container View. The menubar view needs to contain the button to toggle the menu, and the actual menu needs to contain the buttons to set the corresponding view in the Container View. Almost everything is controlled in the storyboard, and the outlets are listed below.
// The Container View
@property (weak, nonatomic) IBOutlet UIView *container;
// The Menu Bar View, with the button to toggle the menu.
@property (weak, nonatomic) IBOutlet UIView *menuBar;
// The Dropdown Menu
@property (weak, nonatomic) IBOutlet UIView *menu;
// The array of buttons in the dropdown menu
@property (nonatomic) IBOutletCollection(UIButton) NSArray *buttons;
// Gesture Recognizer for the Super View, used to dismiss the menu
@property (nonatomic, strong) IBOutlet UITapGestureRecognizer *tapRecognizer;
// Actions for the menu button (show/hide menu) and list button (option in dropdown menu).
