如何向 UILocalNotification 警报添加操作 buttons/actions?
How can I add action buttons/actions to UILocalNotification alert?
我在我的应用程序中安排了一个本地通知,现在当我向左滑动提醒时,我会看到一个通用的取消(十字)按钮。
我很好奇我是否可以像下图那样为其添加自定义 buttons/actions?
我为您准备了一些代码片段,它在 ViewDidLoad
方法显示后 10 秒通过一个按钮显示通知。
import UIKit
class TestViewController: UIViewController {
let category = UIMutableUserNotificationCategory()
override func viewDidLoad() {
super.viewDidLoad()
let restartAction = UIMutableUserNotificationAction()
restartAction.identifier = "xx"
restartAction.destructive = false
restartAction.title = "Restart"
restartAction.activationMode = .Background
restartAction.authenticationRequired = false
let categoryIdentifier = "category.identifier"
category.identifier = categoryIdentifier
category.setActions([restartAction], forContext: .Minimal)
category.setActions([restartAction], forContext: .Default)
let categories = Set(arrayLiteral: category)
let settings = UIUserNotificationSettings(forTypes: [.Alert, .Sound], categories: categories)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
let localNotif = UILocalNotification()
localNotif.alertBody = "testBody"
localNotif.category = categoryIdentifier
// Notification will be shown after 10 second (IMPORTANT: if you want to see notification you have to close or put app into background)
localNotif.fireDate = NSDate().dateByAddingTimeInterval(10)
UIApplication.sharedApplication().scheduleLocalNotification(localNotif)
}
}
注意:您必须在 AppDelegate 方法中处理操作:
func application(application: UIApplication, handleActionWithIdentifier identifier: String?,
forLocalNotification notification: UILocalNotification, completionHandler: () -> Void) {
completionHandler()
}
当然我的代码没有它应该的那么干净,但你要知道我写它只是为了演示目的。
这段代码是用Swift写的,但是转换成Objective C应该很简单。
