iOS 中的重复本地通知 [英] Recurring Local Notification in iOS

问题描述

我只是想确保我了解本地通知的工作原理.是不是一旦我运行以下代码一次，我就会每周收到通知?

I just want to ensure I understand how local notifications work. Is it true that once I run the below code one time, I'll have weekly notifications?

//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，这段代码的结果是，我第一次运行应用程序时，我可以执行这段代码，并且通知将每周重复一次，而无需我运行其他代码?

In other words, the result of this code is that the first time I run the app, I can execute this code and the notification will repeat every week without me running additional code?

推荐答案

localNotification.repeatInterval = NSCalendarUnit.WeekOfYear

是的，这将安排每周的本地通知.

Yes this will schedule local notification for every week.
