Question

Here is my code:

 NSString *trimfeedback = [FeedbackTxtString stringByReplacingOccurrencesOfString:@"<br><u>Your 
 answer</u>:<ca>#ya#</ca><br><u>Correct answer</u>:<br>" withString:@"<p>"];

the string which is to be replace will be static and ‘FeedbackTxtString’ can contain text either ‘Correct answer’ or ‘Correct answers’ . I need to implement the OR case as i dont know what will be in ‘FeedbackTxtString’. If FeedbackTxtString contain ‘Correct answers’ then string to be replace should be <br><u>Your answer</u>:<ca>#ya#</ca><br><u>Correct answers</u>:<br>" withString:@"<p>, or if it contains ‘Correct answer’ then string to be replace should be <br><u>Your answer</u>:<ca>#ya#</ca><br><u>Correct answer</u>:<br>" withString:@"<p>
how could i do that ?

Answer 1

Do this:

  if([FeedbackTxtString rangeOfString:@"Correct answers"].location != NSNotFound)
  {
    NSString *trimfeedback = [FeedbackTxtString stringByReplacingOccurrencesOfString:@"<br><u>Your answer</u>:<ca>#ya#</ca><br><u>Correct answers</u>:<br>" withString:@"<p>"];
  }
  else if([FeedbackTxtString rangeOfString:@"Correct answer"].location != NSNotFound)
  {
    NSString *trimfeedback = [FeedbackTxtString stringByReplacingOccurrencesOfString:@"<br><u>Your answer</u>:<ca>#ya#</ca><br><u>Correct answer</u>:<br>" withString:@"<p>"];
  }
