无论消防date如何，只要我加载我的应用程序，UILocalNotification总是显示出来

你好我是新来的迅速和IOS编程。 我已经设置了6个通知，根据一天中的时间，应该每天提醒用户6次。 警报正在运行，但由于某种原因，应用程序首次同时在通知中心内显示全部6条警报。 任何帮助将不胜感激。

这是AppDelegate.swift中的代码

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { // Override point for customization after application launch. let notificationTypes : UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge let notificationSetting : UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil) UIApplication.sharedApplication().registerUserNotificationSettings(notificationSetting) return true } 

这是我的六个不同通知的function

 func prayerAlert (prayerName : String, prayHour : Int, prayMinute : Int) { dateComp.year = Int(currentDate.year) dateComp.month = Int(currentDate.month) dateComp.day = Int(currentDate.day) dateComp.hour = prayHour dateComp.minute = prayMinute dateComp.timeZone = NSTimeZone.systemTimeZone() var calender : NSCalendar = NSCalendar(calendarIdentifier: NSGregorianCalendar)! var date : NSDate = calender.dateFromComponents(dateComp)! var notification : UILocalNotification = UILocalNotification() notification.alertBody = prayerName notification.fireDate = date UIApplication.sharedApplication().scheduleLocalNotification(notification) } 

这就是我在ViewDidLoad中调用函数的地方

 override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. pray.setTimeFormat(0) self.locationManager.requestAlwaysAuthorization() self.locationManager.requestWhenInUseAuthorization() if CLLocationManager.locationServicesEnabled() { self.locationManager.delegate = self self.locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters self.locationManager.startUpdatingLocation() } var timesArray = pray.getDatePrayerTimes(currentDate.year, andMonth: currentDate.month, andDay: currentDate.day, andLatitude: locationManager.location.coordinate.latitude, andLongitude: locationManager.location.coordinate.longitude, andtimeZone: pray.timeZone) var convertedTime = convertPrayArray(timesArray as NSMutableArray) prayerAlert("Time for Fajr", prayHour: convertedTime.hourArray[0], prayMinute: convertedTime.minuteArray[0]) prayerAlert("Time for SunRise", prayHour: convertedTime.hourArray[1], prayMinute: convertedTime.minuteArray[1]) prayerAlert("Time for Dhuhr", prayHour: convertedTime.hourArray[2], prayMinute: convertedTime.minuteArray[2]) prayerAlert("Time for Asr", prayHour: convertedTime.hourArray[3], prayMinute: convertedTime.minuteArray[3]) prayerAlert("Time for Maghrib", prayHour: convertedTime.hourArray[5], prayMinute: convertedTime.minuteArray[5]) prayerAlert("Time for Isha", prayHour: convertedTime.hourArray[6], prayMinute: convertedTime.minuteArray[6]) }

更新： Xcode 7.1•Swift 2.1

问题是，您将date组件设置为localTime区域而不是通知。

添加这个扩展NSDate从NSDate（）返回所需的组件

 extension NSDate { var minute: Int { return NSCalendar.currentCalendar().component(.Minute, fromDate: self)} var hour: Int { return NSCalendar.currentCalendar().component(.Hour, fromDate: self)} var day: Int { return NSCalendar.currentCalendar().component(.Day, fromDate: self)} var month: Int { return NSCalendar.currentCalendar().component(.Month, fromDate: self)} var year: Int { return NSCalendar.currentCalendar().component(.Year, fromDate: self)} func fireDateAt(hr: Int, min: Int) -> NSDate { let date = NSDate() return NSCalendar.currentCalendar().dateWithEra(1, year: year, month: month, day: { hr > date.hour || (hr == date.hour && min > date.minute) ? day : day + 1 }(), hour: hr, minute: min, second: 0, nanosecond: 0 )! } } 

timeZone属性

通知的启动date的时区。

fireDate中指定的date根据此属性的值进行解释。 如果您指定nil（默认值），则启动date被解释为绝对GMT时间，适用于倒数计时器等情况。 如果将一个有效的NSTimeZone对象分配给此属性，则激活date被解释为在时区发生更改时自动调整的挂钟时间; 适合这种情况的例子是闹钟。

 func prayerAlert (prayerName : String, prayHour : Int, prayMinute : Int) { var notification = UILocalNotification() notification.timeZone = NSTimeZone.localTimeZone() notification.alertBody = prayerName notification.fireDate = NSDate().fireDateAt(prayHour, min: prayMinute) UIApplication.sharedApplication().scheduleLocalNotification(notification) }
