【问题描述】：

我正在尝试像这样发送UILocalNotification：

func sendNotifiaction() 
        let notification = UILocalNotification()
        notification.userInfo = [
            "Identifier": self.identifier!
        ]
        notification.alertTitle = "Alarm!"
        notification.alertBody = "test"
        //notification.soundName = "Temporary-bleep-sound.aiff"
        notification.category = "category"

        UIApplication.sharedApplication().scheduleLocalNotification(notification)
    

我试图在这个方法上设置一个断点，它正在被调用和运行，但是通知根本没有发送。

有人知道为什么吗？

【问题讨论】：

您是否允许该应用推送通知？

@Lumialxk 我认为这就是重点，我该怎么做？

你的开火日期在哪里？

【参考方案1】：

你必须先注册通知

UIApplication.sharedApplication().cancelAllLocalNotifications()
let settings = UIUserNotificationSettings(forTypes: .Alert, categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)

这是我在特定时间触发通知的演示

class AppDelegate: UIResponder, UIApplicationDelegate 

    var window: UIWindow?


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 
        // Override point for customization after application launch.

        UIApplication.sharedApplication().cancelAllLocalNotifications()
        let settings = UIUserNotificationSettings(forTypes: .Alert, categories: nil)
        UIApplication.sharedApplication().registerUserNotificationSettings(settings)

        let localNotification1 = UILocalNotification()
        localNotification1.alertBody = "Your alert message at 9:00 pm"
        localNotification1.timeZone = NSTimeZone.defaultTimeZone()
        localNotification1.fireDate = self.getNinePMDate()
        UIApplication.sharedApplication().scheduleLocalNotification(localNotification1)
        return true
    

    func getNinePMDate() -> NSDate? 
        let calendar: NSCalendar! = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
        let now: NSDate! = NSDate()
        let date21h = calendar.dateBySettingHour(21, minute: 0, second: 0, ofDate: now, options: NSCalendarOptions.MatchFirst)
        return date21h
    

【参考方案2】：

您应该在appdelegate 中实现didReceiveLocalNotification，并且您必须手动显示警报视图，并将标题和消息作为通知的alertbody。
