我正试图用两个可能的操作按钮(如“快速回复”和“取消”)创建一个通知,但找不到任何代码示例。请有人在swift 3中解释一下怎么做。
最佳答案
很难给出一个准确的例子来说明你在寻找什么。下面是一个快速的、带有操作的实现。
import UserNotifications
定义类别ID常量
private let categoryID = "Category"
设置并注册
UNUserNotificationCenter
// MARK: - Lifecycle
override func viewDidLoad() {
super.viewDidLoad()
// Configure User Notification Center
UNUserNotificationCenter.current().delegate = self
// Define Actions
let actionShowSomething = UNNotificationAction(identifier: "ShowSomething", title: "Show Something", options: [])
// Define Category
let category = UNNotificationCategory(identifier: categoryID, actions: [actionShowSomething], intentIdentifiers: [], options: [])
// Register Category
UNUserNotificationCenter.current().setNotificationCategories([category])
}
触发通知的示例事件
// MARK: - Actions
@IBAction func sheduleNotification(sender: UIButton) {
// Request Notification Settings
UNUserNotificationCenter.current().getNotificationSettings { (notificationSettings) in
switch notificationSettings.authorizationStatus {
case .notDetermined:
self.requestAuthorization(completionHandler: { (success) in
guard success else { return }
// Schedule Local Notification
self.scheduleLocalNotification()
})
case .authorized:
// Schedule Local Notification
self.scheduleLocalNotification()
case .denied:
print("Application Not Allowed to Display Notifications")
}
}
}
UNUserNotificationCenter
实施// MARK: - Methods
private func scheduleLocalNotification() {
// Create Notification Content
let notificationContent = UNMutableNotificationContent()
// Configure Notification Content
notificationContent.title = "Title"
notificationContent.subtitle = "Subtitle"
notificationContent.body = "Body"
// Set Category Identifier
notificationContent.categoryIdentifier = categoryID
// Add Trigger
let notificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: 10.0, repeats: false)
// Create Notification Request
let notificationRequest = UNNotificationRequest(identifier: "cocoacasts_local_notification", content: notificationContent, trigger: notificationTrigger)
// Add Request to User Notification Center
UNUserNotificationCenter.current().add(notificationRequest) { (error) in
if let error = error {
print("Unable to Add Notification Request (\(error), \(error.localizedDescription))")
}
}
}
处理用户通知授权
private func requestAuthorization(completionHandler: @escaping (_ success: Bool) -> ()) {
// Request Authorization
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (success, error) in
if let error = error {
print("Request Authorization Failed (\(error), \(error.localizedDescription))")
}
completionHandler(success)
}
}
sheduleNotification
实施extension ViewController: UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert])
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse, withCompletionHandler
completionHandler: @escaping () -> Void) {
completionHandler()
}
}
结果
