title: Parse.com - How to pass a nil parameter into cloud code?
body: <p>I'm coding for iOS and calling my cloud code function using the iOS SDK. One of my parameters is sometimes nil which causes an error.</p>
  
  <p>I'd like to be able to pass some form of nil and check it in the cloud code function. My Javascript is weak and I'm not sure if this is a JS issue or a Parse cloud code issue.</p>
