UIToolBar single View Controllers vs Multiple View Controllers
<p>I am using a UIToolBar with multiple UIButtonItems. These button items need to bring up a modal view controller(VC) for setting parameters via pickers sliders etc.</p>

<p>The question is do I use a single VC for all the button items vs separate VCs for each button ?</p>

<p>Right now I am using only one and bringing the proper subview to front hiding others etc but it seems to be getting tedious particularly with differing nav bar headings, view sizes etc.</p>

<p>So what is the right way - a single VC or separate vc for each UIButtonItem on the UIToolBar ?</p>
