Problem
I have an array that holds several `NSMutableDictionary` objects. Each time text fields are filled out and the submit button is pressed: ``` //The strings NSString *dateString = @"Date"; NSString *timeString = @"Time"; NSString *typeString = @"Type"; - (IBAction)addData:(id)sender { [_myDictionary setObject:_dateLabel.text forKey:dateString]; [_myDictionary setObject:_nNumber.text forKey:timeString]; [_myDictionary setObject:_type.text forKey:typeString]; [_myArray addObject:_myDictionary]; [self display] } ``` Then I am trying to display the results in a UItextView (in this example the date) but I don't know how. ``` -(void)displayData{ for (int i = 0; i<_myArray.count; i++) { [_myArray objectAtIndex:i]; outputString = [outputString stringByAppendingFormat:@"%@\n",[_myDictionary objectForKey:@"Date"]]; } _myTextView.text = [NSString stringWithFormat:@"%@",outputString]; } ``` This ends up displaying the date for the last Dictionary in the array. I can't even figure out how to log the date from a specific dictionary. Say `[_myArray objectAtIndex:3] [_myDictionary objectForKey:@"Date"]`. How would I log the date from the 3rd index? Hope this makes sense ``` EDIT SOLUTION for (int i = 0; i<_myArray.count; i++) { outputString = [outputString stringByAppendingFormat:@"%@ %@\n",[[_myArray objectAtIndex:i]objectForKey:@"Date"], [[_myArray objectAtIndex:i]objectForKey:@"Time"]]; } _myTextView.text = [NSString stringWithFormat:@"%@",outputString]; } ``` Thanks for all the quick help!!
