How to create an alarm clock app with swift?

你说的曾经没有我的故事 提交于 2019-12-04 14:03:23
I'm trying to create a kind of alarm clock app with the swift but I could not figure out how to set an alarm model. I've tried UILocalnotification but I don't want my users to be involved the flow of alarm app other than setting the alarm. Then tried NSTimer and NSRunloop etc. but that didn't work either since those don't work when app gets background. So is there any alternative ways to do that? Any help and suggestion would be appreciated, thanks. I have been doing research on this for quite some time now. But didn't find any concrete way to do it. You have to use one of the following from

Head First C 第十章 进程间通信 闹钟

Head First C 第十章 进程间通信 闹钟 主要介绍一个函数, alarm() , alarm() 的作用是:接收一个无符号整型参数,作为定时的秒数,系统会计时,时刻到达时,给进程发送一个SIGALRM的信号。 关于alarm() 注意 不要同时使用alarm和sleep,两个函数都会使用间隔计时器,会发生冲突。 一个进程中只使用一个alarm()。 重置信号与忽略信号:SIG_DFL和SIG_IGN,它们分别代表以 默认的方式 和 忽略 来处理信号。 catch_signal(SIGINT,SIG_DFL) 使用alarm() alarm(120); 表示在120秒后发送SIGALRM信号给进程,如果多次设置,则以最后一次的为准,前面的设置会失效。 闹钟例程 这小节内容实在乏善可陈,最大的篇幅是代码。 alarm function sample 来源: oschina 链接: https://my.oschina.net/u/2491285/blog/661465

UILocalNotification fires after reinstalling the app

喜你入骨 提交于 2019-12-04 05:33:48
My app has an alarm function using UILocalNotification, and it works great. However, if the user uninstalls the app, then later REINSTALLS it, he would receive all the "in between" notifications at once. I have tried to call: [[UIApplication sharedApplication] cancelAllLocalNotifications]; if it's the first time the app is launched, but it doesn't help, because the notification is received even before application:didFinishLaunchingWithOptions: is called. This was worse in 4.0 when the alarm was repeated even if the user has deleted the app, but at least that bug was fixed by Apple in later

Android AlarmManager and Service question

做~自己de王妃 提交于 2019-12-04 05:22:42
问题 There are some files in my app, but only 3 of them is important now. It's a reminder app with alarm sound and notifications. I hava a maincode.java file containing a checkbox and its listener. If user checks in the chechbox an AlarmManager sends an intent to AlarmReceiver.java, which starts MyService.java. MyService java contains code about playing sound. Code is partial. MyService.java: public void onCreate() { Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show(); Log.d(TAG,

问题 I'm trying to create an alarm using the new Alarm class in the Windows Phone 7.1 SDK I'm able to get it to work but the alarm doesn't seem to be going off at the time i've set. Alarm alarm = new Alarm("MyAlarm") { Content = "Alarm!", BeginTime = DateTime.Now.AddSeconds(seconds), }; ScheduledActionService.Add(alarm); 回答1: The remarks in MSDN say The action will not be invoked before the begin time has been reached. (emphasis mine) There is no guarantee on the alarm being called at the exact

Android. Alarm Manager fires in strange times

I used the following code to set repeating alarm (every 5 minutes). public void SetAlarm(Context context) { AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent i = new Intent(context, Alarm.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 60 * 5, pi); // Millisec * Second * Minute } Is seems to work fine (it runs almost 20 hours), and in the server I can see that some constant message arrives. However, there is something about the times: I want the times to be

Android Alarm What is the difference between four types of Alarm that AlarmManager provides and when to use what?

问题 I want to know the difference between RTC, RTC_WAKEUP, ELAPSED_REALTIME, ELAPSED_REALTIME_WAKEUP . I want to write an alarm application where I will set alarm and close my application and expect for alarm for the time set. There will be multiple alarms. Right now I am writing for emulator but later will test on device. In emulator, once I set the alarm and close the emulator and restart it, then will it be cleared, as I find with RTC, RTC_WAKEUP and ELAPSED_REALTIME. I am confused. Should I

Chrome Extension Alarms go off when Chrome is reopened after time runs out?

牧云@^-^@ 提交于 2019-12-03 16:49:37
When using Google Chrome extension alarms, the alarm will go off if it was set and Chrome is closed and reopened after the time expires for the alarm. How can I stop this? Here is a small code sample to explain what I mean. /* If we perform Browser Action to create alarm, then close the browser, wait about 2 minutes for the alarm to expire and then reopen the browser, the alarm will go off and the DoSomething function will get called twice, once by the onStartup event and once by the onAlarm event. */ chrome.browserAction.onClicked.addListener(function (tab) { chrome.alarms.create('myAlarm', {
