Bear in mind you are moving the co-ordinate system to the object, not
the object around the co-ordinate system...
I find it useful to "read" NSAffineTransform operations in reverse
order. The operations you list in the code are applied to the object
in the opposite order.

Will test this too, but I don't think it will work.
In my case I moved rectangle from it's real position to zero, then
rotate around zero and then moved back.
In your case I will move it far from zero and then rotate...
But I will give it a try.

Shouldn't be this instead (check the translations' signs) ?
[tr translateXBy:dx yBy:dy]; // center or rect will be the center of
rotation
[tr rotateByDegrees:90]; // rotate it
[tr translateXBy:-dx yBy:-dy]; // move it back
