Usted puede encontrar un tutorial un poco avanzado, pero this fine tutori Al por Ray Wenderlich realmente te ayudará y, en lo que respecta a plit, debes buscarlo primero ya que puedes encontrar muchos de ellos.

mejores deseos,

de Apple Drawing and Printing Guide es su amigo. Básicamente, si puede dibujar en la pantalla, puede dibujar en un PDF en iOS (y Mac OS X).
