Question

I have a plist dictionary with several arrays where each have different number of items. These items are dictionaries too. So basically it looks like this:

• Root dictionary
  • names array
  • places array
  • Item 0 dictionary
  • Item 1 dictionary
  • placeName string: “House”
  • description string: “My House”
  • height number: 10
  • Item 2 dictionary
  • …
  • colors array
  • …

I want to find the best way to change a value inside one of these arrays (placeName, description, height).

The plist is part of the resources, so I call it in like this:

[[NSMutableDictionary alloc] initFromName:@"mydefaults.plist"];

I’ve seen the setValue:forKey methods, but it looks like I’m heading into a mess.
I don’t think I should have to be setting the whole complete array if it’s just one value.

So, which is the best way?

Answer 1

How about something along the lines of

[[[plistDictionary objectForKey:@"places"] objectAtIndex:1] setValue:@"Another house" forKey:@"placeName"]

if the “internal” arrays and dictionaries are indeed mutable.
