Weird Compiler WARNING... help? - Elphaba - Aug 10, 2009 10:42 PM
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.
