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.

Enclose the definition in brackets:

case HWDrawState:
{
  HWShape *shape = [[HWShapeManager sharedInstance] addShapeWithType:_shapeClass];
}
break;
case ...
