title: Cloning/Copying an NSMutableArray in Objective C
body: <p>How are arrays cloned or copied into other arrays in Objective-C?</p>
  
  <p>I would like to have a function which when passed in an NSMutableArray, it takes the array and fills up  another array with the content.</p>
  
  <p>Is it as simple as someArray = passedInArray? OR os there some initWith function?</p>
