架构armv7的未定义符号 - 使用Xcode 6.0.1和Cocos2d-x 3.2

Question

当我选择“Build Active Architecture Only”=“YES”时，我可以在我的设备中运行该项目。但是当我选择“否”时，它会显示同一项目中的200多个错误。

前提是，我选择标准体系结构（armv7，arm64）作为架构，arm64，armv7，armv7s作为此项目的有效架构。

以下是我收到的错误的一部分：

Answer 1

仅在有效的架构以及游戏和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）

Answer 2

我已在我的Cocos2d-x 3.7项目中使用以下设置修复了此问题。

• 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”
• 还要确保将架构设置为“标准架构arm7，arm64”

请务必为cocos2d_libs.xcodeproj重复此过程

当类引用缺少的框架时，有时也会显示相同的错误消息。在我的情况下，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中创建一个新项目），其中“Build Active Architecture Only”选项需要为所有目标设置为“No”才能修复'Undefined符号的错误。
