Let me try to explain it. Please tell me if I am wrong. I am just 70% sure about it.

Like I understand it, an UIView has a frame and an bounds rectangle.
The job of the frame rectangle is to set the position of the UIView relative to it’s superview. More precisely: Relative to the coordinate system of the superview. The job of the bounds rectangle is to set the drawing area of the UIView, relative to it’s own coordinate system.

Briefly:

  • frame rectangle is for positioning the UIView relative to its superview
  • bounds rectangle is to set the drawing area of the UIView

Are there any mistakes or important things I missed?

    Check out Apple’s guide on View Geometry. They have pretty good examples on what happens when you change bounds and frame values.
