Does UIOffsetMake() use the traditional top left corner origin (0,0) or bottom left origin?

Question

View geometry in UIKit specifies that it acts on an axis starting from the top left corner (0,0) and increasing in x and y as you travel toward the bottom right.

UIOffsetMake() is used a lot in UIKit Dynamics, and I was wondering if it follows a similar model. It's used to specify, relative to the center of the UIView, where you want the point where the view gets pushed to originate from.

If I specify UIOriginMake(5.0, -5.0) does it change it from the center to further in the bottom right? As in it goes down 5 vertically and 5 over horizontally? Or does it follow the traditional UIView model where that would indicate it goes 5 points over horizontally and 5 points up vertically?

I have no reason to think it doesn't follow UIView's model, but I wasn't positive and I wanted to make sure.

Answer 1

You'll find the answer in the docs for the UIOffset struct:

The components are positive for right or down, negative for left or up.
