title: Toolbar overlaps statusbar only for iPhone 4/4s
body: <p>I'm facing this annoying problem with my App layout.
  As you can see from the image at following <a href="https://photos-3.dropbox.com/t/2/AADvFPSsvLlHQrb1f58r8FGl6FOJng9DpoHPifaHjgW-Xw/12/333654050/jpeg/32x32/1/1439460000/0/2/Senzanome.gif/CKLQjJ8BIAEgAiADIAQgBSAGIAcoAg/6_fKTMrAeu32e64HrxeVip4an6R2j0Gb9Iqf-aGSxtY?size=1280x960&amp;size_mode=2" rel="nofollow">link</a>, toolbar is overlapping the statusbar only for iPhone 4/4s (next devices it works perfectly).
  It's a 4 years old app, Objective-C written, I'm "inheriting" it from old dev team that never noticed this issue.<br>
  Thanks!  </p>
