Hi.

IF I have the following code, everything compiles fine - no errors, no warnings.

Code:

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event withView:(UIResponder *)receivingView

{

    for (UITouch * touch in touches)

    {    

        CGPoint point = [touch locationInView:receivingView];

        _numberOfActiveTouches++;

        NSLog(@"Active Touches = %i, Touch at : %f",_numberOfActiveTouches, point);

    }

}

However, if I add this one line below the NSLog line...

Code:

        [self touchDownDetected:point];

So the method looks like this

Code:

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event withView:(UIResponder *)receivingView

{

    for (UITouch * touch in touches)

    {    

        CGPoint point = [touch locationInView:receivingView];

        _numberOfActiveTouches++;

        NSLog(@"Active Touches = %i, Touch at : %f",_numberOfActiveTouches, point);

        [self touchDownDetected:point];

    }

}

then I get the following compiler WARNING...

warning: passing argument 1 of 'locationInView:' from distinct Objective -C type

I can't work out why... what am I missing?

The method that's being called is this:

Code:

- (void) touchDownDetected:(CGPoint) point

{

    // Blah blah blah

}

Fixed it... Grrrr...

replaced the (UIResponder *) with (UIView *)

and it's all good.

Sorry.
