XCode:架构arm64错误的未定义符号

Question

在我的XCode 5项目中,我使用RestKit进行REST通信.使用模拟器一切正常,但生成ipa文件,我收到以下错误:

ld: warning: ignoring file /Users/joseph/Library/Developer/Xcode/DerivedData/XXXXXXXXXX-gdwdekevxtdfivfpsnmyykeqhulk/Build/Products/Debug-iphoneos/libRestKit.a, missing required architecture arm64 in file /Users/joseph/Library/Developer/Xcode/DerivedData/XXXXXXXXXXXXX-gdwdekevxtdfivfpsnmyykeqhulk/Build/Products/Debug-iphoneos/libRestKit.a (2 slices)

ld: symbol(s) not found for architecture arm64

如果在RestKit项目中,我通过标准体系结构(包括64位)(ARMv7,armv7s,arm64)选项更改"构建设置" - >"体系结构""标准体系结构(ARMv7,armv7s)",一切都编译良好.这是正确的吗？,没有带来任何结果,我必须改变一些其他设置.

Answer 1

1. 选择 Restkit 项目
2. 将仅构建活动架构设置为No

Answer 2

它只是意味着您正在为64位(iPhone 5s)构建项目而无需担心,请参阅此链接以获取更多解释: Xcode 5和iOS 7:架构和有效架构
