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"]


good question. Not sure honestly. My expectation would be that it'd either barf trying to call setDescription on array.

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.


KVC has documentation on this, including the funky array behavior I think.
