title: How can I find out which run loop a certain NSTimer is on if it was created with scheduledTimerWithTimeInterval?
body: <p>If I made an NSTimer with scheduledTimerWithTimeInterval, then according to the documentation, it should be added to the current run loop. I'd like to know how to check which run loop an NSTimer is on. </p>
  
  <p>Also, if a timer is invalidated and a new one is created, how can I add the new timer to the <strong>same</strong> run loop that the first timer was on? </p>
  
  <p>Thanks in advance. </p>
