How to retrieve the contents of a TEXT FILE stored locally in the documents directory?

From stackoverflow

• Assuming the text is UTF-8 encoded:

  NSData *textFileData = [NSData dataWithContentsOfFile:pathToTextFile];
  NSString *textFileString = [NSString stringWithUTF8String:[textFileData bytes]];
  

• You can also use this NSString class method (assuming the text is UTF-8):

  NSString *content = [NSString stringWithContentsOfFile:pathToTextFile encoding:NSUTF8StringEncoding error:&error];
  

  error should be a pointer to an NSError object.
