title: iPhone Persistent Storage
body: <p>I need to store certain information while my application is executing and again fetch it at the time the application starts. I tried storing it in XML using GData but didn't succeed.
  I used the NSFileHandle it doesn't give me an error but it fails to create a .txt file for read / write purpose. Is there any other way of storing and retrieving the data on the iPhone. Below is my code for NSFileHandle.</p>
  
  <pre><code>NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"myFile.txt"];
  //NSFileHandle *fh = [NSFileHandle fileHandleForWritingAtPath:@"file://localhost/Users/shraddha/Desktop/info.txt"];
  NSFileHandle *fh = [NSFileHandle fileHandleForWritingAtPath:@"myFile.txt"];
  [fh seekToEndOfFile];
  NSData *data = [camName dataUsingEncoding:NSASCIIStringEncoding];
  [fh writeData:data];
  [fh closeFile];
  </code></pre>
  
  <p>For Reading</p>
  
  <pre><code>NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"myFile.txt"];
  //NSFileHandle *fh = [NSFileHandle fileHandleForReadingAtPath:@"file://localhost/Users/shraddha/Desktop/info.txt"];
  NSFileHandle *fh = [NSFileHandle fileHandleForReadingAtPath:@"myFile.txt"];
  if(fh == nil)
      return nil;
  else
  {
      NSData *data = [fh readDataOfLength:8];
      NSString *retStr = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
      return retStr;
  }
  </code></pre>
