OC与Swift中的 description

Swift 中重写父类description方法,输出模型中的内容

// 重写基类中description属性
    override var description:String {
        let keys =   ["access_token","uid","remind_in","screen_name","avatar_large"]
        return dictionaryWithValuesForKeys(keys).description
    }

OC中 在自定义的类中,将其中的属性在description中赋值,并返回

- (NSString *)description {
    return [NSString stringWithFormat:@"<%@: %p, name: %@,  age: %@>", NSStringFromClass([self class]), self, self.name, self.session, self.age];
}
