title: How do I pass more than one parameter to the selector in 'scheduledTimerWithTimeInterval:target:selector:userInfo:repeats:'
body: <p>I know user info is used to pass a parameter, but how do I pass more than one of these?</p>
  
  <p>I'm guessing I have to use an object, but as I am fairly new to objective-c I don't really know if this is right and how to go about it?</p>
  
  <p>Thanks!</p>
