iOS 中的定期本地通知

Recurring Local Notification in iOS

我只是想确保我了解本地通知的工作原理。一旦我 运行 下面的代码一次,我每周都会收到通知,这是真的吗?

//Goes in AppDelegate.swift
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.

    //Added this for notifications. 
    //Without this, I don't believe the user gets the opportunity to approve notifications from the app
    let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge], categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(settings)

    return true
}

//Goes in viewController
func weeklyNotifications () {
    let localNotification = UILocalNotification()
    localNotification.fireDate = NSDate(timeIntervalSinceNow: 60*60)
    localNotification.alertBody = "This is the message"
    localNotification.timeZone = NSTimeZone.localTimeZone()
    localNotification.repeatInterval = NSCalendarUnit.WeekOfYear
    localNotification.soundName = UILocalNotificationDefaultSoundName
    localNotification.category = "Message" //Optional
    UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
}

换句话说,此代码的结果是我第一次 运行 应用程序时,我可以执行此代码并且通知将每周重复一次,而无需我 运行 额外的代码?

localNotification.repeatInterval = NSCalendarUnit.WeekOfYear

是的,这将安排每周的本地通知。
