Create NSArray with specific property

Question

I have an NSArray called carparkArr that contain MyCarpark objects. This class contain:

@property (nonatomic, assign) CLLocationCoordinate locationCoord;

Now I want to create an array that will have NSValue of each of these objects. How to do it quickly? I want something like:

NSArray *carparkArr = // fetching data
NSArray *locationProperty = [self getArrayForPropertyPath:@".locationCoord" forArray:carparkArr];

Yeah that feature already exists:

NSArray *locationProperty = [carparkArr valueForKey:@"locationCoord"];

Is that CLLocationCoordinate is a structure isn't a problem? NSArray cannot handle not NSObject elements.

@Szu KVC will wrap it automatically within an NSValue or NSNumber object.

Thanks. I didn't think Foundation framework is so smart!
