我需要我的应用程序存储一些应该在特定时间启动的本地通知.
I need my application to store some local notifications that should be launched on a specific time.
我的申请很简单.用户可以使用 UIDatePicker 预订时间.通知将在预订时间前 2 分钟发出.
My application is simple. The user can book times using a UIDatePicker. The notification is to be fired 2 minutes before that booked time.
现在我正在尝试手动插入应该触发通知的时间.我正在使用此代码:
For now i am trying to manually insert a time that the notification should be fired at. I am using this code:
let notification = UILocalNotification() self.timePicked = " 22:38:00 +0000" timeForLocalPush = defaults.objectForKey("timeForLocalPush") as! String timeForLocalPush = timeForLocalPush + self.timePicked print(timeForLocalPush) // this prints for this example today, 2016-08-30 22:38:00 +0000 dateFormatter.dateFormat = "YYY-MM-dd" notification.fireDate = dateFormatter.dateFromString(timeForLocalPush) notification.timeZone = NSCalendar.currentCalendar().timeZone notification.alertBody = self.nameField.text! + " Har bokat tid nu!" UIApplication.sharedApplication().scheduleLocalNotification(notification)发生的情况是在预订时间后立即触发通知.想要的动作是这样的:
What happens is that the notification is fired instantly after booking the time. Desired action is this:
当前时间:14:17
客户预定时间:15:00
Client books for this time: 15:00
本地通知设置为触发:14:58
Local notification is set to be fired: 14:58
如果您需要任何其他信息,请告诉我.谢谢
If you need any additional information just tell me. Thank you
推荐答案最初检查你的日期格式是错误的 dateFormatter.dateFormat = "YYY-MM-dd", it is in dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
initially check your date format it is in wrong dateFormatter.dateFormat = "YYY-MM-dd", it is in dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
例如
let localNotification1 = UILocalNotification() localNotification1.alertBody = "Your alert message " localNotification1.timeZone = NSCalendar.currentCalendar().timeZone let formatter = NSDateFormatter() formatter.dateFormat = "yyyy-MM-dd HH:mm:ss" localNotification1.fireDate = formatter.dateFromString("2016-08-30 22:38:00") UIApplication.sharedApplication().scheduleLocalNotification(localNotification1)更多推荐
