ios – 启用Bitcode导出时出错(架构armv7找不到符号)

概述我有一个相当旧的项目,最低部署目标设置为iOS 8.4.由于技术原因,必须启用bitcode.该项目建立并运行良好.然而,当尝试导出存档的构建时,事情就出错了.我正在使用 Xcode 8.2.1. 当我使用选项Rebuild from bitcode创建测试版本(使用Enterprise证书签名)时,导出在编译bitcode时失败. 以下是日志的相关部分： "/Applications/Xcode 我有一个相当旧的项目,最低部署目标设置为iOS 8.4.由于技术原因,必须启用bitcode.该项目建立并运行良好.然而,当尝试导出存档的构建时,事情就出错了.我正在使用 Xcode 8.2.1.

当我从bitcode禁用Rebuild时,导出成功,生成的构建运行正常.但是,当构建将提交给iTunes Connect时,我担心会出现问题.

有没有人知道为什么会出现这个错误以及如何解决这个问题？我在这里有点不知所措.

编辑：

澄清：是的,bitcode在目标级别启用.以下是链接库：

这些是依赖项：

# Reportingpod 'Fabric'pod 'Crashlytics'pod 'GoogleAnalytics'pod 'CocoaLumberjack','~> 1.6.2'# Networkingpod 'AFNetworking','~> 2.6.3'pod 'RestKit','~> 0.27'pod 'Reachability'# Otherpod 'UIcolor-UtilitIEs','~> 1.0.1'pod 'VIEwDeck','~> 2.4'pod 'SDWebImage','~> 3.7.0'pod 'AMratingControl','~> 1.3.0'

解决方法 经过一些试验和错误以及 Sven Drielecker(和其他人)的有用建议后,问题已得到解决.

对于调试和发布版本,GCC_INSTRUMENT_PROGRAM_FLOW_ARCS构建设置都设置为YES.将其关闭以便发布已经解决了这个问题.
