Mantle

// Mantle is a framework that allows you to interchange JSON formatted data into model objects.

// You can read more about it here: https://github.com/Mantle/Mantle

// Using mantle is simple, create an object that inerhits from MTLModel, and it must also implement MTLJSONSerializing protocol.

#import <Mantle/Mantle.h>

@interface ModelObject : MTLModel <MTLJSONSerializing>

@property (nonatomic) NSString *name;
@property (nonatomic) NSString *zipCode;

@end

@implementation LMDrug

+ (NSDictionary *)JSONKeyPathsByPropertyKey {
    return @{};
}

@end

// That's all you need!

// Given JSON that looks like this:

// {
//    "name": "Caleb Hicks",
//    "zipCode": "84062"
//  }
//

// You can turn that into your model object with the following code
NSError *error = nil;
NSDictionary *data = @{@"name": @"Caleb Hicks", @"zipCode", @"84062"};
ModelObject *model = [MTLJSONAdapter modelOfClass:[ModelObject class] fromJSONDictionary:data error:&error];

// To turn the model object back into JSON, use the following code:
NSDictionary *data = [MTLJSONAdapter JSONDictionaryFromModel:model];

// If you have an array of objects, you can use this code
NSArray *arrayOfModels = [MTLJSONAdapter modelsOfClass:[ModelObject class] fromJSONArray:arrayOfThings error:&error];

// Make sure to always handle the errors
if (error) {
  // Handle Error
}
