应用程序未运行时的本地通知

Question

是否可以显示来自应用程序的某种本地通知，即使该应用程序未运行（也不在后台）？

例如每日提醒之类的。我知道推送通知是可行的，但它不适合我的应用程序。

Answer 1

您可以轻松安排本地通知，它们将在安排的日期和时间呈现，而不管应用程序的状态如何。

首先您需要获得用户的许可才能显示通知，如下所示：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound|UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil))
    return true
}

然后像这样创建通知：

var localNotification:UILocalNotification = UILocalNotification()
localNotification.alertAction = "This is"
localNotification.alertBody = "A notification"
localNotification.fireDate = NSDate(timeIntervalSinceNow: 15)
UIApplication.sharedApplication().scheduleLocalNotification(localNotification)

看看Local and Remote Notification Programming Guide。

Answer 2

在 AppDelegate 中，改用此函数

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
    application.registerUserNotificationSettings(settings)
    return true;
}
