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

It is pretty simple and clean if you do it with NSThread. With no need to subclass it.

- (void)backgroundStuff {
    while (!self.cancelThread) {
        // do your work
        [NSThread sleepForTimeInterval:0.01];
    }
}

Just an ordinary function. cancelThread is a member variable you declare. Start it with

[NSThread detachNewThreadSelector:@selector(backgroundStuff) toTarget:self withObject:nil];

and you can cancle the thread anytime with self.cancelThread = true;
