IOS 9和10中的本地和推送通知使用swift3
我在iOS 10开发了local Notifications 。 这是完美的工作。 但是，现在如何编码local notifications和push notification如果用户使用iOS 9及以上版本。 任何人都可以帮忙吗？
以下是iOS 10代码
import UIKit import UserNotifications @available(iOS 10.0, *) class ViewController: UIViewController,UNUserNotificationCenterDelegate { override func viewDidLoad() { super.viewDidLoad() if #available(iOS 10.0, *) { //Seeking permission of the user to display app notifications UNUserNotificationCenter.current().requestAuthorization(options: [.alert,.sound,.badge], completionHandler: {didAllow,Error in }) UNUserNotificationCenter.current().delegate = self } } //To display notifications when app is running inforeground func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { completionHandler([.alert, .sound, .badge]) } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } @IBAction func buttonPressed(_ sender: UIButton) { if #available(iOS 10.0, *) { //Setting content of the notification let content = UNMutableNotificationContent() content.title = "hello" content.body = "notification pooped out" content.badge = 1 //Setting time for notification trigger let date = Date(timeIntervalSinceNow: 10) var dateCompenents = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute, .second], from: date) let trigger = UNCalendarNotificationTrigger(dateMatching: dateCompenents, repeats: false) //Adding Request let request = UNNotificationRequest(identifier: "timerdone", content: content, trigger: trigger) UNUserNotificationCenter.current().add(request, withCompletionHandler: nil) } } }
本地通知
IOS 11 ： – 您可以在iOS 11中使用以下代码。在推送和本地通知中不需要进行任何types的更改
if #available(iOS 10.0, *) { //iOS 10 or above version let center = UNUserNotificationCenter.current() let content = UNMutableNotificationContent() content.title = "Late wake up call" content.body = "The early bird catches the worm, but the second mouse gets the cheese." content.categoryIdentifier = "alarm" content.userInfo = ["customData": "fizzbuzz"] content.sound = UNNotificationSound.default() var dateComponents = DateComponents() dateComponents.hour = 15 dateComponents.minute = 49 let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true) let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger) center.add(request) } else { // ios 9 let notification = UILocalNotification() notification.fireDate = NSDate(timeIntervalSinceNow: 5) as Date notification.alertBody = "Hey you! Yeah you! Swipe to unlock!" notification.alertAction = "be awesome!" notification.soundName = UILocalNotificationDefaultSoundName UIApplication.shared.scheduleLocalNotification(notification) let notification1 = UILocalNotification() notification1.fireDate = NSDate(timeIntervalSinceNow: 15) as Date notification1.alertBody = "Hey you! Yeah you! Swipe to unlock!" notification1.alertAction = "be awesome!" notification1.soundName = UILocalNotificationDefaultSoundName UIApplication.shared.scheduleLocalNotification(notification1) }
推送通知
import UserNotifications if #available(iOS 10.0, *) { //iOS 10 or above version UNUserNotificationCenter.current().delegate = self UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert], completionHandler: {(granted, error) in if (granted) { UIApplication.shared.registerForRemoteNotifications() } else{ //Do stuff if unsuccessful... } }) } else{ //iOS 9 let type: UIUserNotificationType = [UIUserNotificationType.badge, UIUserNotificationType.alert, UIUserNotificationType.sound] let setting = UIUserNotificationSettings(types: type, categories: nil) UIApplication.shared.registerUserNotificationSettings(setting) UIApplication.shared.registerForRemoteNotifications() }
UIApplicationDelegate
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { let tokenParts = deviceToken.map { data -> String in return String(format: "%02.2hhx", data) } let token = tokenParts.joined() print(token) } func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { }
UNUserNotificationCenterDelegate
仅在ios 10及以上版本中可用
@available(iOS 10.0, *) func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { } @available(iOS 10.0, *) func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) { }
我已经为Swift 3做了这个类，它具有请求许可推送通知和发送通知的function。 适用于iOS 9和iOS 10+。
import UIKit import UserNotifications class LocalNotification: NSObject, UNUserNotificationCenterDelegate { class func registerForLocalNotification(on application:UIApplication) { if (UIApplication.instancesRespond(to: #selector(UIApplication.registerUserNotificationSettings(_:)))) { let notificationCategory:UIMutableUserNotificationCategory = UIMutableUserNotificationCategory() notificationCategory.identifier = "NOTIFICATION_CATEGORY" //registerting for the notification. application.registerUserNotificationSettings(UIUserNotificationSettings(types:[.sound, .alert, .badge], categories: nil)) } } class func dispatchlocalNotification(with title: String, body: String, userInfo: [AnyHashable: Any]? = nil, at date:Date) { if #available(iOS 10.0, *) { let center = UNUserNotificationCenter.current() let content = UNMutableNotificationContent() content.title = title content.body = body content.categoryIdentifier = "Fechou" if let info = userInfo { content.userInfo = info } content.sound = UNNotificationSound.default() let comp = Calendar.current.dateComponents([.hour, .minute], from: date) let trigger = UNCalendarNotificationTrigger(dateMatching: comp, repeats: true) let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger) center.add(request) } else { let notification = UILocalNotification() notification.fireDate = date notification.alertTitle = title notification.alertBody = body if let info = userInfo { notification.userInfo = info } notification.soundName = UILocalNotificationDefaultSoundName UIApplication.shared.scheduleLocalNotification(notification) } print("WILL DISPATCH LOCAL NOTIFICATION AT ", date) } }
用法：
您可以在任何地方申请权限
LocalNotification.registerForLocalNotification(on: UIApplication.shared)
并发送本地通知：
LocalNotification.dispatchlocalNotification(with: "Notification Title for iOS10+", body: "This is the notification body, works on all versions", at: Date().addedBy(minutes: 2))
小费：
您可以将通知设置为在将来的任何date触发，在本示例中，我使用date扩展来获取通知火灾的未来date。 就是这个：
extension Date { func addedBy(minutes:Int) -> Date { return Calendar.current.date(byAdding: .minute, value: minutes, to: self)! } }
