NSArray and NSSet additions for Key-Value filtering
NSArray and NSSet categories for Key-Value filtering
Demo time :
// Quick and easy search
NSArray * employees = [...]
Person * ceo = [employees firstObjectWithValue:@"[email protected]" forKeyPath:@"email"];
// Keypaths
Person * steve = [employees firstObjectWithValue:[NSNull null] forKeyPath:@"car.licenseplate"]
// Keypath collection operators
NSArray * boxes = [...]
NSArray * emptyBoxes = [boxes filteredArrayWithValue:@0 forKey:@"items.@count"];
More details on my blog.
