ios - 终止app swift 2后发送本地通知

Question

当应用程序状态进入终止/未运行状态时，可以在某个特定时间后执行某些特定任务。

func applicationDidEnterBackground(application: UIApplication) {
    print("APP in background state") // Working fine
    NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: "backService", userInfo: nil, repeats: true)

}

但是当应用程序状态进入终止状态时，它就无法正常工作了吗？

func applicationWillTerminate(application: UIApplication) {
     NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: "backService", userInfo: nil, repeats: true)
}

我也试过

func applicationWillTerminate(application: UIApplication) {

    let application = UIApplication.sharedApplication()
    self.applicationDidEnterBackground(application)
    application.beginBackgroundTaskWithExpirationHandler { 
                    NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: "backService", userInfo: nil, repeats: true)
    }

}

Answer 1

只要您的应用程序正在运行，就可以安排本地通知、取消和重新安排

然后如果它被关闭，通知将不再被取消并且会触发!
