原文连接   果然是苹果打个哈欠,iOS行业内就得起一次风暴呀.自从5月初Apple明文规定所有开发者在6月1号以后提交新版本需要支持IPV6-Only的网络,大家便开始热火朝天的研究如何支持IPV6,以及应用中哪些模块目前不支持IPV6. 一.IPV6-Only支持是啥? 首先IPV6,是对IPV4地址空间的扩充.目前当我们用iOS设备连接上Wifi.4G.3G等网络时,设备被分配的地址均是IPV4地址,但是随着运营商和企业逐渐部署IPV6 DNS64/NAT64网络之后,设备被分配的地址会变…

写在前面 最近的一个iOS App项目中遇到了这么问题:通过App访问服务器的大多数资源不需要登录,但是访问某些资源是需要用户提供验证的,一般来说,通常App的做法(譬如美团App)将这些资源放在“我的”模块,在未登录情况下,当点击“我的”某个模块时,以modally给出一个界面用于登录,我不晓得美团是怎么实现的:但在我看来,比较优雅的方式是在网络底层实现“modally呈现登录界面”,具体来说,当用户欲访问“我的购物券”时,在网络访问层发现用户未登录,就弹出一个登陆界面,用户登录成功后,就将这…
