Hi all.

I've got an array that has KVP dicts in each record that report a Name property and a GPS string.

Is there any lovely one liner that is able to return the values of a specific property for all elements in the array of dicts as an array of those values?

Like so:

I'd like to go from:

myArray: ( { Name = "Puppies"; geocode = "42.40283381228625, -71.2597588506239"; }, { Name = "Kittens"; geocode = "42.40283381228625, -71.2597588506239"; } )

to:

myNameArray: ( "Puppies", "Kittens" )

I know I can do this and add the NSStrings to a NSMutableArray, then convert that to an NSArray, but I was hoping the experts already have this in a much cleaner approach.

for (NSDictionary *myArrayMember in myArray) { NSString *nameValue = [myArrayMember objectForKey:@"Name"]; // add NameValue String to array here. NSLog(@" %@", nameValue); }

Thanks in advance, - Alex Zavatone
