【问题描述】：

当我选择“仅构建活动架构”=“是”时，我可以在我的设备中运行该项目。但是当我选择“否”时，它会显示同一个项目的 200 多个错误。

如果我选择标准架构（armv7、arm64）作为架构，而 arm64、armv7、armv7s 作为此项目的有效架构。

这是我收到的部分错误：

【解决方案1】：

仅在有效架构以及游戏和 cocos2d-x 项目的架构部分添加 armv7 和 armv7s。（在项目和目标部分构建设置中）

【讨论】：

【解决方案2】：

我已经通过在我的 Cocos2d-x 3.7 项目中使用以下设置解决了这个问题。

在 Xcode 中选择您的顶级项目（在本例中为“ZooCubes”）
将 iOS 部署目标设置为“iOS 7”
将有效架构设置为：“arm64 arm7”
还要确保架构设置为“标准架构 arm7、arm64”

确保对 cocos2d_libs.xcodeproj 重复此过程

有时，当类引用缺少的框架时，也会显示相同的错误消息。就我而言，我必须添加 GameKit 框架，因为我的一个类试图引用它。

最后，我还遇到了一些情况（例如在 cocos2dx-2.2.6 中创建新项目），需要将所有目标的“仅构建活动架构”选项设置为“否”以修复“未定义”符号错误。
