【问题描述】：

我正在学习 restkit api。我找到了一个非常好的Raywenderlichrestkit 教程。但它与 Restkit 0.10.1 集成。我想学习一个 RestKit-0.20.0-pre6。如果有人在ios中有这样的好教程。请分享。提前致谢。

【参考方案1】：

Raywenderlich 终于更新了新 RestKit 的教程 http://www.raywenderlich.com/58682/introduction-restkit-tutorial

【讨论】：

修复 alexedge 的第一个链接：github.com/RestKit/RestKit/issues/832，然后从构建阶段删除脚本

看看这个网站也restkit-tutorials.com

自 2015 年 2 月起，有一个全新的教程，介绍如何将 RestKit 与 CoreData 结合使用 medium.com/ios-os-x-development/…

【参考方案2】：

我发现下面的代码可用于 RestKit 0.20。
