You might consider: Examining the boolean result from calling cancel() on your task, as it should indicate if your request succeeds or fails Try purge() or cancel() on the Timer instead of the TimerTask If you do not necessarily need Timer and TimerTask, you can always use postDelayed() (available on Handler and on any View). … Read more
The persistent property means that the container is required to persist the timer state to a database. This is important if you need to guarantee that the timer will fire even if the server is taken offline (intentionally or crash). When the server comes back online, it is required to execute missed timers. Setting a … Read more
Had some trouble with this myself. There isn’t a lot of good documentation, so I went with experimentation. Here’s what I was able to determine: mach_absolute_time depends on the processor of the device. It returns ticks since the device was last rebooted (otherwise known as uptime). In order to get it in a human readable … Read more
While maybe gifsockets would work (I haven’t tried that before…), there is no network traffic while I am looking at the image other than the initial image load. I am also seeing it it jump from 41 to 42 again. A Reload took it down to 39. It appears to be just a script that … Read more
CountDownTimer waitTimer; waitTimer = new CountDownTimer(60000, 300) { public void onTick(long millisUntilFinished) { //called every 300 milliseconds, which could be used to //send messages or some other action } public void onFinish() { //After 60000 milliseconds (60 sec) finish current //if you would like to execute something when time finishes } }.start(); to stop the … Read more
It’s safe. The issue is probably to do with stopTimer not being set as you expect.
Stopwatch is based on High resolution timer (where available), you can check that with IsHighResolution
Don’t use NSTimer that way. NSTimer is normally used to fire a selector at some time interval. It isn’t high precision and isn’t suited to what you want to do. What you want is a High resolution timer class (using NSDate): Output: Total time was: 0.002027 milliseconds Total time was: 0.000002 seconds Total time was: … Read more
Create a delay, which then sets the @State property hasTimeElapsed to true when the time has elapsed, updating the view body. With Swift 5.5 and the new concurrency updates (async & await), you can now use task(_:) like the following: struct ContentView: View { @State private var hasTimeElapsed = false var body: some View { … Read more
If it is acceptable to block the main thread when user haven’t provided an answer: from threading import Timer timeout = 10 t = Timer(timeout, print, [‘Sorry, times up’]) t.start() prompt = “You have %d seconds to choose the correct answer…\n” % timeout answer = input(prompt) t.cancel() Otherwise, you could use @Alex Martelli’s answer (modified … Read more
