Code used in the screencast are included in the bundled sample project.

Demo Project

To run the demo project, clone the repo with git clone https://github.com/Azuritul/AZDropdownMenu.git, and run pod install from the Example directory first.

Requirements

• iOS 8 or above
• Xcode 8 or above
• Swift 3

Installation

AZDropdownMenu is available through CocoaPods. To install it, simply add the following line to your Podfile:

use_frameworks!
pod 'AZDropdownMenu'

Usage

Declare an array of texts that are served as the item in the menu.

let titles = ["Action 1", "Action 2", "Action 3"]

Then pass the array to the initializer

let menu = AZDropdownMenu(titles: titles)

Set up so that the UIBarButtonItem is associated with a function that shows the menu

let button = UIBarButtonItem(image: UIImage(named: "menu_image"), style: .Plain, target: self, action: "showDropdown")
navigationItem.leftBarButtonItem = menuButton

Calling public func showMenuFromView(view:UIView) can then show the menu.

func showDropdown() {
    if (self.menu?.isDescendantOfView(self.view) == true) {
        self.menu?.hideMenu()
    } else {
        self.menu?.showMenuFromView(self.view)
    }
}

The handler public var cellTapHandler : ((indexPath:NSIndexPath) -> Void)? would be called when menu item is tapped. So place code in here to do whatever you want. For example

menu.cellTapHandler = { [weak self] (indexPath: NSIndexPath) -> Void in
    self?.navigationController?.pushViewController(controller, animated:true)
}

Create menu with icons

Pass in a AZDropdownMenuItemData in the initializer: public init(dataSource:[AZDropdownMenuItemData]) and you are good to go.

Take a look at the sample project in this repository to get more usage of the library.
