当我将架构更新为 arm64 时，Restkit 失败
Restkit fails when I update architecture to arm64
当我将项目架构更新为 64 位时，出现了这些问题。我的部署目标是 7.1.

您的 RestKit 似乎是旧版本。最简单的方法可能是使用 CocoaPods。打开终端，输入：
$ sudo gem install cocoapods
然后在终端中转到您的项目文件夹并键入：
$ pod init
打开 .podfile 并插入此行：
pod 'RestKit', '~> 0.24'
保存并退出文件。在终端写：
$ pod install
从现在开始，您应该使用 .xcwrokspace 而不是 .xcproj。您还应该删除旧版本的 RestKit.
另一种选择是使用 git 子模块 或 hg subrepos。我不会在这里输入教程，因为要写的太多了，cocoapods 对于新手来说更容易。
另一种选择是下载更新的 RestKit 版本并将其添加到您的项目中 "from hand" - 拖放。我 不推荐 这种方式，因为您永远不知道自己使用的是哪个版本，也看不到使用过的框架有新的更新（显然经常修复错误）。
