title: How to get date from a string (iPhone)?
body: <pre><code>I need to convert this string in to the date:
  
      02-09-2011 20:54:18
  
  I am trying the `dateFromString` method but every time it is returning (null), what NSDateFormatter should I use?, I have tried
  `[formatter setDateFormat:@"yyyy-MM-dd"]` and `[formatter setDateFormat:@"yyyy-MM-dd hh:mm:ss"]`.
  
  
  Here is my code:
  NSString *finalDate = @"02-09-2011 20:54:18";
  NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
  [formatter setDateFormat:@"yyyy-MM-dd"];
  
  NSDate *dateString = [formatter dateFromString:finalDate];
  NSLog(@"%@",dateString);
  
  
  Thanks.
