    Hi all...

    I am looking to create a thread application, which will go on running through out. Also i want to make the thread to start as soon as the phone starts...
    The thing is that how to check the current time inside a thread to trigger a operation

    Actually my thread is one which download a xml file at every 24hrs.. say everyday 01.00 am....

    The SDK explicitly prevents background applications. You cannot do what you want to do.

    Only if you jailbreak your phone, which is the only way to run non-Apple background applications.

    Using the SDK what you describe is specifically forbidden by Apple.

    wait a little...
    in september apple will release some mechnism to send notifications to apps so they can be "awaken" at will
    for now i would advise you to just load the xml file on startup or maybe check if it is still valid (in your case the last midnight update...) and invest your time consolidating the rest of the application

    :)

    Not quite true. You can send an alert to ask the user if they want to launch the app. But there's no way to know that they've just turned their phone on to send the notification.

    i was talking about application startup

    maybe i did not fully understand what you´re trying todo

    usually for the user any data will only be relevant after application launch so it can be updated at that time

    the info on the upcoming notifications scheme has been around since wwdc, even today or yesterday there are news aaround bout it on the new 2.1 sdk preview

    The notification service does not awaken apps or cause them to do any processing. All it does is alert you to the fact that you might want to run a particular app.
