Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate SwiftyMenu into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'SwiftyMenu', '~> 0.6.5'

Usage

Storyboard

We are supporting Generic Data Source, all you have to do is conforming to our Generic Protocol on which type you want to add to the menu:

// Example on String. You can change it to what ever type you want ;)
// String extension to conform SwiftyMenuDisplayable Protocl
extension String: SwiftyMenuDisplayable {
    public var displayableValue: String {
        return self
    }
    
    public var retrivableValue: Any {
        return self
    }
}

Then setup your view controller:

// Connect view in storyboard with you outlet
@IBOutlet private weak var dropDownMenu: SwiftyMenu!

// Define your Generic items array)
private let items: [SwiftyMenuDisplayable] = ["Option 1", "Option 2", "Option 3", "Option 4"]

// Assign the component that implement SwiftyMenuDelegate to SwiftyMenu component
dropDownMenu.delegate = self

// Give array of items to SwiftyMenu
dropDownMenu.items = items

Then implement SwiftyMenuDelegate:

extension ViewController: SwiftyMenuDelegate {
    // Get selected option from SwiftyMenu
    func swiftyMenu(_ swiftyMenu: SwiftyMenu, didSelectItem item: SwiftyMenuDisplayable, atIndex index: Int) {
        print("Selected item: \(item), at index: \(index)")
    }
    
    // SwiftyMenu drop down menu will expand
    func swiftyMenu(willExpand swiftyMenu: SwiftyMenu) {
        print("SwiftyMenu willExpand.")
    }

    // SwiftyMenu drop down menu did expand
    func swiftyMenu(didExpand swiftyMenu: SwiftyMenu) {
        print("SwiftyMenu didExpand.")
    }

    // SwiftyMenu drop down menu will collapse
    func swiftyMenu(willCollapse swiftyMenu: SwiftyMenu) {
        print("SwiftyMenu willCollapse.")
    }

    // SwiftyMenu drop down menu did collapse
    func swiftyMenu(didCollapse swiftyMenu: SwiftyMenu) {
        print("SwiftyMenu didCollapse.")
    }
}

Also you can use callbacks to know what happen:

// Support different callbacks for different events
dropDownMenu.didExpand = {
    print("SwiftyMenu Expanded!")
}

dropDownMenu.didCollapse = {
    print("SwiftyMeny Collapsed")
}

dropDown.didSelectItem = { menu, item, index in
    print("\(item) at index: \(index)")
}

CustomizeUI

You can configure SwiftyMenu from Storyboard or Code as following:

// Change option's row height (default 35)
dropDownMenu.rowHeight = 35

// Change option's drop down menu height 
// default is 0, which make drop down height = number of options * rowHeight
dropDownMenu.listHeight = 150

// Change drop down menu border width
dropDownMenu.borderWidth = 1.0

// Change drop down menu scroll behavior 
dropDownMenu.scrollingEnabled = false

// Change drop down menu default colors
dropDownMenu.borderColor = .black
dropDownMenu.itemTextColor = .red
dropDownMenu.placeHolderColor = .blue
dropDownMenu.menuHeaderBackgroundColor = .lightGray
dropDownMenu.rowBackgroundColor = .orange
dropDown.separatorColor = .white

// Change drop down menu default expand and collapse animation
dropDownMenu.expandingAnimationStyle = .spring(level: .low)
dropDownMenu.expandingDuration = 0.5
dropDownMenu.collapsingAnimationStyle = .linear
dropDownMenu.collapsingDuration = 0.5
