With regards to auto-correction, I was able to add it using link. Here's the code snippet I used from the link:

UITextChecker *checker = [[UITextChecker alloc] init];

  NSRange checkRange = NSMakeRange(0, self.txView.text.length);

  NSRange misspelledRange = [checker rangeOfMisspelledWordInString:self.txView.text 
                                                             range:checkRange
                                                        startingAt:checkRange.location
                                                              wrap:NO 
                                                          language:@"en_US"];

  NSArray *arrGuessed = [checker guessesForWordRange:misspelledRange inString:self.txView.text language:@"en_US"];

  self.txView.text = [self.txView.text stringByReplacingCharactersInRange:misspelledRange 
                                                               withString:[arrGuessed objectAtIndex:0]];
