    --mj_enumerateProperties

    -->properties-- cachedPropertiesDict_缓存,mj_enumerateClasses(enumeration回调自己和父类 + class_copyPropertyList,遍历 - (cachedPropertyWithProperty:封装MJProperty),(propertyKey:替换key)setOriginKey:设置propertyKeysDict,(propertyObjectClassInArray数组中需要转换的模型类)setObjectClassInArray:设置objectClassInArrayDict)

    -->  enumeration回调所有cachedProperties


    使用:

    (1)简单字典 -> 模型

    (2)简单JSON -> 模型

    (3)复杂字典 -> 模型 (模型中有模型,模型中有数组中有模型)

    (4)简单字典 -> 模型 (key替换,多级映射)

    [模型类  mj_objectWithKeyValues:~~]

    (5)字典数组 -> 模型数组

    [模型类  mj_objectArrayWithKeyValuesArray:~~]

    (6)模型 -> 字典

    [模型实例  mj_keyValues:~~]

    [模型实例  mj_keyValuesWithKeys:~~]

    (7)多级映射模型

    [模型实例  mj_keyValues:~~]

    [模型实例  mj_keyValuesWithIgnoredKeys:@[]]

    [模型实例  mj_JSONString]

    (8)模型数组 -> 字典数组

    [模型类  mj_keyValuesArrayWithObjectArray:]

    (9)Core Data && NSCoding


    模型 -> 字典

    跟着MJExtension实现简单的字典转模型框架
