【KakaJSON手册】08-其余用法

除了完成JSON和Model的转换以外，KakaJSON内部还有不少实用的功能，有些也开放为public接口了

遍历属性

struct Cat {
    var age: Int = 0
    let name: String = ""
}

guard let type = Metadata.type(Cat.self) as? ModelType,
    let properties = type.properties else { return }

for property in properties {
    print(property.name,
          property.type,
          property.isVar,
          property.ownerType,
          property.offset)
    // age Int true Cat 0
    // name String false Cat 8
}
