架构armv7的未定义符号-使用xcode6.0.1和cocos2d-x3.2

Question

当我选择"Build Active Architecture Only“= "YES”时，我可以在我的设备上运行该项目。但当我选择"NO“时，它显示同一个项目有200多个错误。

我选择了标准架构(armv7，arm64)作为这个项目的架构，选择了arm64，armv7，armv7s作为这个项目的有效架构。

以下是我收到的错误的一部分：

Answer 1

仅在游戏和cocos2d-x项目的有效架构和架构部分添加armv7和armv7s。(在项目和目标剖面构建设置中)

Answer 2

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

• 在Xcode中选择您的顶级项目(在本例中，'ZooCubes')
• Set iOS部署目标设置为"iOS 7“
• 将有效架构设置为："arm64 arm7”
• 还确保将架构设置为“iOS architectures arm7，arm64"

请确保对cocos2d_libs.xcodeproj重复此过程

有时，当一个类引用了一个缺失的框架时，同样的错误消息也会显示出来。在我的例子中，我必须添加GameKit框架，因为我的一个类正在尝试引用它。

最后，我还遇到了这样的情况(例如，在cocos2dx-2.2.6中创建一个新项目)，所有目标的"Build Active Architecture Only“选项都需要设置为”No“，以便修复”Undefined symbols“错误。
