macOS Drawing a grid in Core Graphics

[Blakeasd]

Hello Everyone,
I am trying to create a grid using a custom view, but I just can't get it how I want it. I am trying to draw something very simple, but it's not working. This is what I am trying to draw:

Does anyone know how to draw this in a custom view? Thanks

Very much this! One thing I would note: if you want crisp lines then draw at 0.5 increments. The reasons for this are due to the way Quartz anti-aliases. So a line from (0,0.5) to (10,0.5) would look like a crisp single-pixel line and (0,0) to (10,0) would look like it was straddling the pixel boundary and be anti-aliases across two pixels.
