如何在特定时间每天在特定时间触发本地通知3

Question

我是iOS开发新手，但已经创建了该应用程序，并且正在尝试为特定时间（例如（10AM））创建每日通知。现在，如果我的移动设备时间到达上午10点，通知就会变得太多。我想在给定的特定时间点上午10点触发本地通知，我想每天重复一次。每天重复通知的最佳方法是什么？

这里是我的代码

func fire(){ 
    let dateComp:NSDateComponents = NSDateComponents() 
    dateComp.hour = 10 
    dateComp.minute = 00 
    dateComp.timeZone = NSTimeZone.systemTimeZone() 
    let calender:NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierIndian)! 
    let date:NSDate = calender.dateFromComponents(dateComp)! 
    let localNotificationSilent = UILocalNotification() 
    localNotificationSilent.fireDate = date 
    localNotificationSilent.repeatInterval = NSCalendarUnit.Day 
    localNotificationSilent.alertBody = "Started!" 
    localNotificationSilent.alertAction = "swipe to hear!" 
    localNotificationSilent.timeZone = NSCalendar.currentCalendar().timeZone 
    localNotificationSilent.category = "PLAY_CATEGORY" 
    UIApplication.sharedApplication().scheduleLocalNotification(localNotificationSilent)  
}

你的问题是消防日这是不正确的

您可以创建火日期一样，如果你想验证火灾日期这样

let today = Date() 
    let calendar = NSCalendar.current 
    let components = calendar.dateComponents([.day, .month, .year], from: today) 

    var dateComp:DateComponents = DateComponents() 
    dateComp.day = components.day 
    dateComp.month = components.month 
    dateComp.year = components.year 
    dateComp.hour = 10 
    dateComp.minute = 00 
    let date = calendar.date(from: dateComp) 

那么你可以这样检查

let dateFormatter = DateFormatter() 
    dateFormatter.dateFormat = "dd MM yyyy hh:mm:ss" 
    let fireDate = dateFormatter.string(from: date!) 
    print("fireDate: \(fireDate)") 

现在是时候火日期设置为本地通知

localNotificationSilent.fireDate = date 
// no need to set time zone Remove bellow line 
localNotificationSilent.timeZone = NSCalendar.currentCalendar().timeZone 

通知码

let localNotificationSilent = UILocalNotification() 
    localNotificationSilent.fireDate = date 
    localNotificationSilent.repeatInterval = .day 
    localNotificationSilent.alertBody = "Started!" 
    localNotificationSilent.alertAction = "swipe to hear!" 
    localNotificationSilent.category = "PLAY_CATEGORY" 
    UIApplication.shared.scheduleLocalNotification(localNotificationSilent) 

我希望这会帮助你。

在夫特3，iOS的10个工作：

UNUserNotificationCenter.current().requestAuthorization(
    options: [.alert, .sound, .badge], completionHandler: {userDidAllow, error in 
    //if userDidAllow : do something if you want to 
}) 

//Set notification to trigger 11:30AM everyday 
var dateComponents = DateComponents() 
dateComponents.hour = 11 
dateComponents.minute = 30 
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true) 

//Set your content 
let content = UNMutableNotificationContent() 
content.title = "Your notification title" 
content.body = "Your notification body" 

let request = UNNotificationRequest(
    identifier: "yourIdentifier", content: content, trigger: trigger 
) 
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
