title: Objective C - Read plaintext multicolumn file into several column arrays
body: <p>I have seen several threads about file handling in Objective C but can't find a simple systematic way to do this: let's say you have a multicolumn data files where each x y z ... columns are separated by tabs. What I want to do is just converting each column to a specific array. I have almost no experience with Objective C but I do know C++.</p>
  
  <p>Thank you in advance.</p>
