3DTouch的分享菜单是上架后系统自动加上的，其他的菜单需要我们自定义。

1.定义菜单项Model

import Foundation

enum ShortcutItem {
    case scan
    case send
    case receive
    case qrcode
    var type: String {
        switch self {
        case .scan:
            return "com.app.scan"
        case .send:
            return "com.app.send"
        case .receive:
            return "com.app.receive"
        case .qrcode:
            return "com.app.qrcode"
        }
    }
    var title: String {
        switch self {
        case .scan:
            return "Scan".localized
        case .send:
            return "Send".localized
        case .receive:
            return "Receive".localized
        case .qrcode:
            return "My referral code".localized
        }
    }
    var imageName: String {
        switch self {
        case .scan:
            return "shortcut_scan"
        case .send:
            return "shortcut_send"
        case .receive:
            return "shortcut_receive"
        case .qrcode:
            return "shortcut_qrcode"
        }
    }
    var icon: UIApplicationShortcutIcon {
        return UIApplicationShortcutIcon(templateImageName: self.imageName)
    }
}

2.在APPDelegate中设置ShortcutItems

func createShortcutItems() {
        if #available(iOS 9.1, *) {
            var itemArray: [UIApplicationShortcutItem] = []
            for item in [ShortcutItem.scan, ShortcutItem.send, ShortcutItem.receive, ShortcutItem.qrcode] {
                itemArray.append(UIApplicationShortcutItem(type: item.type, localizedTitle: item.title, localizedSubtitle: nil, icon: item.icon, userInfo: nil))
            }
            UIApplication.shared.shortcutItems = itemArray
        }
    }

3.实现点击Item事件

func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {
        guard let appDelegate = UIApplication.shared.delegate as? AppDelegate else { return }
        guard let main = appDelegate.coordinator.coordinators.first as? MainCoordinator else { return }
        switch shortcutItem.type {
        case ShortcutItem.scan.type:
            print("scan")
        case ShortcutItem.send.type:
           print("send")
        case ShortcutItem.receive.type:
            print("receive")
        case ShortcutItem.qrcode.type:
            print("qrcode")
        default:
            break
        }
    }
