title: How to read/write file with iOS, in simulator as well as on device?
body: <p>As I need to read a file when my app is launched and write it sometimes while using it, I tried to reach it with :</p>
  
  <pre><code>NSString *dataFile = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"txt"];
  NSLog(@"%@",dataFile);
  </code></pre>
  
  <p>And the file, that should be in my project folder, is instead in the simulator folder :</p>

  <p>So if I want to read/write it in using the simulator as well as the real device, what should I do ?</p>
  
  <p>Thanks for your advices</p>
