Question

我正在寻找一个中心，每天为徽章图标添加1。我尝试了多种方法，但没有更新图标徽章编号。

override func viewDidLoad() {
    super.viewDidLoad()


    let localNotification:UILocalNotification = UILocalNotification()
    localNotification.fireDate = datePicker.date
    localNotification.alertBody = nil;
    localNotification.alertAction = nil;
    localNotification.timeZone = NSTimeZone.defaultTimeZone()

    localNotification.repeatInterval = NSCalendarUnit.Day

    //Add one to the icon badge number

    localNotification.applicationIconBadgeNumber = UIApplication.sharedApplication().applicationIconBadgeNumber + 1;


    UIApplication.sharedApplication().scheduleLocalNotification(localNotification)

Answer 1

所以我会选择另一种方法。我的想法是设置一个自动重复计时器，每隔86,400（24小时/ 1天）启动并发送通知。如果可行，徽章计数将自动增加一个。

//!pseudo-code!
let timer = NSTimer.scheduledTimerWithTimeInterval(864000, target: self, selector: "sendNotification:", userInfo: nil, repeats: true)

func sendNotification(timer: NSTimer) {
    //initialize and send your notification w/ repeatCount: 0 and fireDate: now
    //hide the banner so the user does not visually see the notification if you wish
}

我不确定如果应用程序没有运行，这是否会起作用，但可能值得一试。
