objective C switch problem

Question

My code looks like down this:

-(void)touchBegan:(HWPoint *)point { switch (self.states) { case HWDrawState: HWShape *shape = [[HWShapeManager sharedInstance] addShapeWithType:_shapeClass]; break; case HWSelectState: break; case HWDeleteState: break; default: break; } }

Why is there a problem with HWShape.... ? I got an error with it:

"error: expected expression before 'HWShape'".

Why is that? Thank you very much for replys.

states sounds like it is an integer with multiple bit-flags. case does only mask if states is exactly equal to one of the enum values. — Georg Schölly

Enclose the definition in brackets:
