title: Has anyone implemented the PayPal API through a native iPhone app?
body: <p>It seems the only way to stay "in app" is to give them a UIWebView of the paypal mobile site and let them complete the transaction there, otherwise the user would need to use their API key.</p>
  
  <p>Does this sound right and has anyone got or seen any sample code?  I have to think this is a common piece of code.</p>
  
  <p>UPDATE:
  Will Apple allow this?
  It is a charity app, so I am assuming there is no issue.</p>
  
  <p>Re-UPDATE:
  I assumed wrong.
  Apple will not allow payments directly within apps using paypal. You have to re-direct to a web interface.</p>
