Worker Thread iOS

Question

I want to create a background thread on the iPhone that executes some code every 10msec. But before I get lost in the concurrency programming guide and the threading program

Answer 1

You could easily use GCD (grand central dispatch) for that. First create a selector that will be called in the background. From here call whatever method you want.

- (void)backgroundSelector
{
    // do whatever you want to do
    [self performSelector:@selector(backgroundSelector) withObject:nil afterDelay:0.01];
}

After that just fire this method for the first time like this

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{
    [self backgroundSelector];
});

Let me know if that works for you.
