edit

here nslog text:

and uilabel text:

the marked text @ nslog missing uilabel.. sorry language.

what cause problem? gooing crazy, tried everything!! in advance!

there few reasons why label won't display text

  1. frame size, looks cover especaily since can see of text
  2. the font/size/wording big , in turn doesn't have enough space show text.

in case suggest looking @ font or font size.
