Swift 中重寫父類description方法,輸出模型中的內(nèi)容

// 重寫基類中description屬性
    override var description:String {
        let keys =   ["access_token","uid","remind_in","screen_name","avatar_large"]
        return dictionaryWithValuesForKeys(keys).description
    }

OC中 在自定義的類中,將其中的屬性在description中賦值,并返回

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