Features

🎡 Try: Includes an iOS & macOS demo.

• Provide items either programmatically or from a JSON configuration file.
• Dark mode.
• + more!

iOS

• Supports push buttons—a segmented item's subitems become push buttons.

• iOS 13: action items use the new context menu interaction:

  Note: Due to an internal assertion, the keyboard can no longer remain visible during the interaction.

  

macOS

• Supports push, action, & segmented control toolbar items.
• Provides NSMenuItems for each item.

Requirements

• iOS 10.0+ (12.0+ for dark mode)
• macOS 10.12+ (10.13+ for full functionality)

Installation

Ribbon is available for installation using Carthage or CocoaPods.

Carthage

github "chriszielinski/Ribbon"

CocoaPods

pod "Ribbon"

Usage

There are two ways of integrating Ribbon into your project:

Configuration File

🔥 The recommended approach.

The configuration file makes for a quick & easy integration. The default configuration filename is ribbon-configuration.json and should be copied into the target's bundle resources (in the Copy Bundle Resources build phase).

The JSON below defines a single action item and toolbar configuration—which is only relevant for the macOS platform.

🧐 See: Demos/Shared/ribbon-configuration.json for a more comprehensive example.

{
    "items": [
        {
            "action": "actionItemHandler",
            "controlKind": "action",
            "identifier": "action-item-identifier",
            "imageName": "NSActionTemplate",
            "keyEquivalent": "a",
            "keyEquivalentModifier": ["command", "shift"],
            "title": "Action Item",
            "toolTip": "The action button's tool-tip.",
            "subitems": [
                {
                    "action": "firstActionSubitemHandler",
                    "identifier": "first-action-subitem",
                    "imageName": "hand.thumbsup",
                    "keyEquivalent": "1",
                    "keyEquivalentModifier": ["command"],
                    "title": "First Action Subitem",
                    "toolTip": "The first action's tool-tip."
                },
                {
                    "action": "secondActionSubitemHandler",
                    "identifier": "second-action-subitem",
                    "imageName": "hand.thumbsdown",
                    "keyEquivalent": "2",
                    "keyEquivalentModifier": ["command"],
                    "title": "Second Action Subitem",
                    "toolTip": "The second action's tool-tip."
                }
            ]
        }
    ],
    "toolbar": {
        "displayMode": "iconOnly",
        "sizeMode": "regular",
        "identifier": "toolbar-identifier",
        "defaultItems" : ["NSToolbarFlexibleSpaceItem", "action-item-identifier"]
    }
}

Integration into your view controller is as simple as:

📌 Note: The code below is an abstraction and will not compile.

import Ribbon

class YourViewController ... {

    ...
    
    var ribbon: Ribbon!

    override func viewDidLoad() {
        ribbon = try! Ribbon.loadFromMainBundle(target: self)

        #if canImport(UIKit)
        textView.inputAccessoryView = ribbon
        #endif
    }
    
    #if canImport(AppKit)
    override func viewWillAppear() {
        view.window?.toolbar = ribbon.toolbar

        super.viewWillAppear()
    }
    #endif
    
    @objc
    func actionItemHandler() { }

    @objc
    func firstActionSubitemHandler() { }

    @objc
    func secondActionSubitemHandler() { }

}

Programmatically

📌 Note: The code below is an abstraction and will not compile.

import Ribbon

class YourViewController ... {

    ...
    
    var ribbon: Ribbon!

    override func viewDidLoad() {
        let firstActionSubitem = RibbonItem(subItemTitle: "First Action Subitem")
        firstActionSubitem.action = #selector(firstActionSubitemHandler)
        let secondActionSubitem = RibbonItem(subItemTitle: "Second Action Subitem")
        secondActionSubitem.action = #selector(secondActionSubitemHandler)

        let actionItem = RibbonItem(controlKind: .action,
                                    title: "Action Item",
                                    subitems: [firstActionSubitem, secondActionSubitem])
        actionItem.action = #selector(actionItemHandler)
        ribbon = Ribbon(items: [actionItem], target: self)

        #if canImport(UIKit)
        textView.inputAccessoryView = ribbon
        #endif
    }
    
    #if canImport(AppKit)
    override func viewWillAppear() {
        view.window?.toolbar = ribbon.toolbar

        super.viewWillAppear()
    }
    #endif
    
    @objc
    func actionItemHandler() { }

    @objc
    func firstActionSubitemHandler() { }

    @objc
    func secondActionSubitemHandler() { }

}
