title: Objective C: How to kill a thread while in another thread in Objective-C?
body: <p>I was trying to set up a multi thread app. One of the threads is working as background to get some data transfer. Right now this thread automatically kill itself after it's job done. 
  Somehow I need to kill this thread in another thread in order stop its job immediately. Are there any api or method for making this happen?</p>
