Keep calling function as long as finger is pressed down

Right now I'm using:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"Function called");
}

which activates on press down, which is correct. But, I also want to continue calling the function, let's say every second, as long as the finger is still on the screen (in other words: until the finger is lifted up).

How would I go about doing this?

Start timer when touch down and end timer when touch up. – CrimsonChris Sep 24 '14 at 02:43
