JSON 到 NSObject 的映射庫：Motis

Motis 使用 Cocoa 的 KVC 實現了智能的 JSON 到 NSObject 對象的映射。

示例代碼：

// --- User.h --- //

@interface User : NSObject

@property (nonatomic, strong) NSString *name;
@property (nonatomic, assign) NSIntger userId;
@property (nonatomic, strong) NSDate *creationDate;
@property (nonatomic, strong) NSURL *website;
@property (nonatomic, assing) NSInteger views;
@property (nonatomic, assing) NSInteger ranking;

@end

// --- User.m --- //

@implementation User

+ (NSDictionary*)mts_mapping
{
    return @{@"user_name": mts_key(name),
             @"user_id": mts_key(userId),
             @"creation_date": mts_key(creationDate),
             @"website": mts_key(website),
             @"user_stats.views": mts_key(views),  // <-- KeyPath access
             @"user_stats.ranking": mts_key(ranking), // <-- KeyPath access
            };
}

@end
