title: How do I build multiple versions of the same iOS application for OEMs
body: <p>I have an existing iOS application that I need to be able to build and release multiple versions of for different clients.</p>
  
  <p>This application interfaces with hardware that is available from a handful of different companies, the hardware is identical but each company sells the hardware under a different name</p>
  
  <p>This is a free app, the goal is not to spam the appstore with multiple versions of the same app, the goal is to allow companies that sell rebranded hardware to have a mobile app that uses the brand name that they use for the hardware.</p>
  
  <p>What I need to be able to do:</p>
  
  <ul>
  <li>Build multiple versions of the same application that can be submitted to the Appstore, each version would be submitted under a different companies apple account.  I would assume that means multiple projects so that each project can use a company specific provisioning profile</li>
  <li>Each version has some different images (Icon, startup image, maybe a few others)</li>
  <li>Each version has some different strings (Company name, Product Name, maybe a few others)</li>
  </ul>
  
  <p>With Android I just create a library project and I can override strings and images with a trivial amount of effort.</p>
  
  <p>With iOS I haven't found an obvious answer.</p>
  
  <p>I looked into adding a new target to my existing project but I don't think that will work:
  - I can't figure out how to replace images beyond the icon and starting screen
  - I can't figure out how to replace strings
  - Would I be able to use different provisioning profiles for the different apps that compile with the same project?  I know the target settings allow different provisioning profiles, but doesn't the project settings have its own set of provisioning profiles?</p>
  
  <p>Can I package the current application into a library that other projects can use and replace images/strings?  So each version would have its own xCode project but use the same code.</p>
  
  <p>Maybe I need to work more with the idea of multiple targets...</p>
  
  <p>I am using xCode 4.2, but I am prepared to move to a newer version if necessary</p>
