Implement Application Shortcut in App using swift 4

Application Shortcut

Application shortcut is the way where we can perform some task fast without open the main App & go to particular section . App Shortcut will directly to specified location , but there is some limitation to use this Shortcut it will support to iPhone 6s to above phone .

There is Some Steps to Follow.

1: Open Your App Delegate File .

a: Here I have taken one shortcut that will go to your Cart Controller in App.

declare their unique key : it is unique key to define the App Shortcut that will help to update this name or other value later .

enum AppShortCutKey:String{

case cartKey = "cartselection"

}

b: Go to this Function in App Delegate file and write this:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

self.setupAppShortCut(application, launchOptions: launchOptions)

}

c: Now we have to define this method:

func setupAppShortCut(_ application: UIApplication,launchOptions: [UIApplicationLaunchOptionsKey: Any]?){

// If a shortcut was launched, display its information and take the appropriate action.

if let shortcutItem = launchOptions?[UIApplicationLaunchOptionsKey.shortcutItem] as? UIApplicationShortcutItem {

launchedShortcutItem = shortcutItem

}

if let shortcutItems = application.shortcutItems, shortcutItems.isEmpty {

let icon1 = UIApplicationShortcutIcon(templateImageName:"ic_cart")

let item1 = UIApplicationShortcutItem(type: AppShortCutKey.cartKey.rawValue, localizedTitle: "cart".localized, localizedSubtitle: "startshopping".localized, icon: icon1, userInfo: nil)

UIApplication.shared.shortcutItems = [item2]

}

Note: Here we are checking the App Shortcut is Created before or not so if is empty than it will create other wise return the previous one.

d: Declare Shortcut Item in Appdelegate.swift class:

class AppDelegate: UIResponder, UIApplicationDelegate {

var launchedShortcutItem: UIApplicationShortcutItem?

}

2: Handle the Click Event Of App Shortcut.

a: Override this method in App Delegate file:

extension AppDelegate{

func handleShortCutItem(_ shortcutItem: UIApplicationShortcutItem) -> Bool {

var handled = false

guard let shortCutType = shortcutItem.type as String? else { return false }

switch shortCutType {

case AppShortCutKey.searchKey.rawValue:

handled = true

NotificationCenter.default.post(name: NSNotification.Name(rawValue: "shortcutsearchtap"), object: nil, userInfo: nil)

break

default:

break

}

return handled

}

func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {

let handledShortCutItem = handleShortCutItem(shortcutItem)

completionHandler(handledShortCutItem)

}

Note: If you click on Any Shortcut item , this method will automatically call so you need to return true for successfully execution.

Here i have taken Local Notification to handle the request.

You have to define this “shortcutsearchtap” in your start viewcontroller in ViewDidload Method.

In Our Case i have start viewcontroller is ViewController.swift class.

class ViewController: UIViewController,UISearchBarDelegate,CategoryViewControllerHandlerDelegate,BrandViewControllerHandlerDelegate,productViewControllerHandlerDelegate,bannerViewControllerHandlerDelegate,UITabBarControllerDelegate, RecentProductViewControllerHandlerDelegate{

override func viewDidLoad() {

super.viewDidLoad()

NotificationCenter.default.addObserver(self, selector: #selector(self.goToCart), name: NSNotification.Name(rawValue: "shortcutcarttap"), object: nil)

}

func goToCart(_ note: Notification) {

self.tabBarController?.selectedIndex = 3

// handle this request

}
