How many paragraphs in a text view?

[fiz]

Hello,

In order for my user to easily edit a plist file, I want to present it into a NSTextView. It is a (mutable) array of (mutable) dictionaries converted in lines (one line per dictionary) of words separated with tabs (the keys). So, for example:
lastname1 firstname1
lastname2 firstname2
…

I already have my plist presented in such a text, I did so:

• (void)dictionaryToText: (id)notification; {
  NSString *tempText;
  tempText = [NSString string];
  for (NSDictionary *tempRec in [dictionary valueForKeyPath:[selector objectValueOfSelectedItem]]) { //selector is a ComboBox (even if I don’t like ComboBoxes)
  NSString *line = [NSString stringWithFormat:@“%@\t%@\n”,[tempRec valueForKey:@“lastName”],[tempRec valueForKey:@“firstName”]];
  tempText = [tempText stringByAppendingString:line];
  }
  self.convertedText = tempText; // where “convertedText” is bound to the textview attributedString.
  }

My problem is: how to put back the modified text into the dictionary? I tried this – of course everything freezes:

• (void)textToDictionary: (id)notification {
  [dictionary removeObjectForKey:[selector objectValueOfSelectedItem]];
  [dictionary setObject:[selector objectValueOfSelectedItem] forKey:[selector objectValueOfSelectedItem]];
  NSString *tempText = self.convertedText;
  NSArray *linesArray =[NSArray arrayWithArray:[tempText componentsSeparatedByString:@“\n”]];
  for (NSString *oneLine in linesArray){
  NSLog(@“oneLine is «%@»”,oneLine);
  if ([oneLine isNotEqualTo: @“”]){ // avoid blank lines!
  NSArray *oneRecord=[NSArray arrayWithArray:[oneLine componentsSeparatedByString:@“\t”]];
  NSDictionary *newRecord = [NSDictionary dictionaryWithObjectsAndKeys:[oneRecord objectAtIndex:0], @“lastName”,[oneRecord objectAtIndex:1], @“firstName”, nil];
  NSLog(@“%@”,newRecord);
  }
  };
  }

[__NSCFString countByEnumeratingWithState:objects:count:]: unrecognized selector sent to instance 0x7f83c5132f80

Well, I’m stuck. Can you help me please ?

I’m not sure of your problem, but this works fine here:

		    NSString *tempText = @"One\tTwo\nThree\tFour";
		    NSArray *linesArray =[tempText componentsSeparatedByString:@"\n"];
		    for (NSString *oneLine in linesArray){
		        NSLog(@"oneLine is «%@»",oneLine);
		        if (![oneLine isEqualToString: @""]){ // avoid blank lines!
		        NSArray *oneRecord= [oneLine componentsSeparatedByString:@"\t"];
		        NSDictionary *newRecord = [NSDictionary dictionaryWithObjectsAndKeys:[oneRecord objectAtIndex:0], @"lastName",[oneRecord objectAtIndex:1], @"firstName", nil];
		        NSLog(@"%@",newRecord);
		        }
		    };

lastName = Three;
}

Thank you Shane,

It was not a strict code error, it was a problem with bindings. You replaced the line

    NSString *tempText = self.convertedText;

with

    NSString *tempText = @"One\tTwo\nThree\tFour";

so the error had to come from here. convertedText was bound to the text view’s attributedString. As soon as I edited something, the app just looked like the Death Star at the end of the movie.

I replaced this line with NSString *tempText = [theTextView string]; and everything works fine now. I just had to put these records into an array and add:

[dictionary setObject: forKey:];

What a relief. I couldn’t figure out what was wrong in the code.

Thank you!
