iPhone6 真机 iOS 9.2.1中，本地通知：
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { // Override point for customization after application launch. 。。。 //enable notification let notifSettings = UIUserNotificationSettings(forTypes: [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound], categories: nil) application.registerUserNotificationSettings(notifSettings) application.beginBackgroundTaskWithName("showNotification", expirationHandler: nil) //reset badge number application.applicationIconBadgeNumber = 0 return true } func sendNotification(newMessage:Message){ var notifTitle = "" var notifBody = "" (notifTitle, notifBody) = genMesageTitleBody(newMessage) print("notifTitle=\(notifTitle), notifBody=\(notifBody)") UIApplication.sharedApplication().cancelAllLocalNotifications() let localNotif = UILocalNotification() localNotif.fireDate = NSDate(timeIntervalSinceNow: 0.1) localNotif.timeZone = NSTimeZone.defaultTimeZone() if #available(iOS 8.2, *) { localNotif.alertTitle = notifTitle } else { // Fallback on earlier versions } localNotif.alertBody = notifBody localNotif.soundName = UILocalNotificationDefaultSoundName localNotif.alertLaunchImage = "" localNotif.applicationIconBadgeNumber = UIApplication.sharedApplication().applicationIconBadgeNumber + 1 UIApplication.sharedApplication().scheduleLocalNotification(localNotif) } |
要等很久才提示
或者根本就不工作，不提示
但是在iOS 模拟器中，却工作的非常稳定：
只要有scheduleLocalNotification就会立刻出发对应的本地通知
swift local notification sometime not work
ios local notification sometime not work
iphone – Local Notification is not working well in ios – Stack Overflow
ios – Local notifications are not working on device but working on simulator – Stack Overflow
ios – Send Local Notifications while App is running in the background Swift 2.0 – Stack Overflow
去加上试试：
【总结】
//enable notification let notifSettings = UIUserNotificationSettings(forTypes: [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound], categories: nil) application.registerUserNotificationSettings(notifSettings) application.beginBackgroundTaskWithName("showNotification", expirationHandler: nil) |
果然可以了：
iPhone6真机 iOS9.2.1中，发了消息后：
马上（等待时间不到1秒）就可以收到本地通知了：
然后锁屏后，也可以显示本地通知了：
