Question

I’m wondering if there is a little bit of code that would do something like highlight a CGPoint, making a dot of some sort on the the CGPoint’s location, or if you were using CGRect, to see exactly where the rectangle is on the simulator, not just the numbers in the code.

I’m fully aware that I could just implement my own way of doing this, like using pictures just as labels or drawing a line of some sort, but I was wondering… Is there a built in thing similar to this? Anything that modifies the simulator’s view so that you can get more information from it?

Answer 1

I tend to do something like this:

- (void) drawRect:(GCRect) rect {
//do my ordinary drawing here

#ifdef DEBUG_DRAWING
// draw whatever I want to visualize some layout I'm doing, 
// typically some NSDrawRect() calls.
#endif
}
