Hi Mr. Jack!

I've tried this but the problem is that by using "[touches allObjects]" the counter is always one, so seems that there's only one finger on the screen, but by using "[event allTouches]" I can't compile because I can't access to the touch via the "[[event allTouches] objectAtIndex:n]" method...

I've tried replacing all my code by the "[touches allObjects]" and the result is:

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
	if ([[touches allObjects] count] > 0) {
		// Hi ha 1 dit a la pantalla
		
		UITouch *t1 = [[touches allObjects] objectAtIndex:0];
		CGPoint touchPos1 = [t1 locationInView:t1.view];
		CGPoint touchPosAnt1 = [t1 previousLocationInView:t1.view];
		
		NSLog(@"1");
		
		if ([[touches allObjects] count] > 1) {
			// Hi ha 2 dits a la pantalla
			
			NSLog(@"2");
	
			for(UITouch *t in [touches allObjects])
			{
				NSLog(@"Luke, I'm your father!");
			}
			
			UITouch *t2 = [[touches allObjects] objectAtIndex:1];
			CGPoint touchPos2 = [t2 locationInView:t2.view];
		}
	}
}

And the console shows:

2010-02-23 10:36:49.175 provaObjectes3D[1996:207] 1
2010-02-23 10:36:49.331 provaObjectes3D[1996:207] 1
2010-02-23 10:36:49.354 provaObjectes3D[1996:207] 1
(repeat ad infinitum...)

So seems that counter is never > 1...

Any clue about this?
