title: Toolbar in an iphone app
body: <p>I'm currently developing an iphone app where I have one screen that includes a web view. I was wondering where to place the toolbar (back, forward, and refresh buttons) knowing that I have to keep the navigation bar for consistency reasons and there is the tab bar which is always showing in my app. I don't want to place the toolbar just under the navigation bar in order not to loose space for the content of the web page. 
  Can I include my toolbar controls (back, forward, and refresh buttons) in the navigation bar or by that I will by violating the iOS guidelines ? What is the best user experience here ? </p>
  
  <p>Thanks in advance.
  Best Regards, </p>
