I am building a custom component, and I’ve decided to build it with a custom UIView in a NIB. There are several other UIView‘s positioned in this same nib document, but all are at the root level.
As you can see, all of these elements have od X/Y that (to me) are not intuitive at all.
The Container UIView: (why does X=122 and Y=42)

The first subcontainer UIView is the top half (first 4 fields)
Why does X=122 and Y=22? Obviously it’s positioned at the top-left of its parent

The second subcontainer UIView is the top half (second 4 fields)
Why does X=122 and Y=62? I would expect it to be positioned at X=0 and Y=43?

See the red cross on the middle of the first Inspector view? Right above the “Origin” label. Click on the upper-left corner and the anchor will move to there, and your coordinate system will be back to normal.
