Array Key-value Paths

  • Subject: Array Key-value Paths
  • From: Sheehan Olver <email@hidden>

I had a question about key-value paths with arrays. If I have a property called "array", then

[self valueForKeyPath:@"array.description"]

returns an NSArray of the description properties of all the objects in "array". So my question is what happens when you call:

[self setValue:descriptionArray
forKeyPath:@"array.description"]

It can't call "setDescription:" on anything because "array" is not populated. I couldn't find a detailed description of key-value paths in the documentation, unless I just looked in the wrong place.

Thanks,
Sheehan Olver
