  also show>>Frame Rectangle x=0 y=20 the label in the simulator looks centered horizontally but not centered vertically. Vertically the label is lower.

  This is almost certainly a conflict between the "classic" iPhone screen size and the new iPhone 5 screen size. You might have your nib file configured for one size, but are running the simulator on a different size. Both of these settings are switchable, of course

  
  

  So what happens is that you may have an object that is vertically centered in one view, but shifts up or down in the other. The reason is that the nib problem contains a constraint that is pinning the object's vertical position to either the top or bottom of its parent view, or to another view. What you want instead is a constraint that pins its vertical center to its superview's vertical center. You'll learn more about constraints as you go through the book. 

  
  

  The short solution is this:

  - Select the object you want centered.

  - From the menu, select Editor > Align > Vertical Center in Container.

  
  

  Then build and run in the simulator. The object should be centered vertically, no matter which device you've selected in the simulator's menu.

  In my case I also had to delete a constraint that put the label at 263 pixels in Y that created itself when I put the label on the View to begin with.
