iOS WeMo SDK 架构问题

Question

我正在尝试构建一个控制 Belkin 的 WeMo Switch 的应用程序。他们发布了自己的 SDK 来控制他们的产品，我已将它们包含在我的库搜索路径以及我的链接库和框架工作区中。

首先，我尝试为所有架构(包括 arm64)进行编译并得到以下 Mach-O Linker Error

ld: warning: ignoring file /Users/khwaab/src/enimai/iOS/House Control/-
iphoneos/BelkinSDKLibrary.a, missing required architecture arm64 in file
/Users/khwaab/src/enimai/iOS/House Control/-iphoneos/BelkinSDKLibrary.a (3 slices)

ld: warning: ignoring file /Users/khwaab/src/enimai/iOS/House Control/-
iphoneos/Reachability.a, missing required architecture arm64 in file 
/Users/khwaab/src/enimai/iOS/House Control/-iphoneos/Reachability.a (3 slices)

Undefined symbols for architecture arm64:

"_OBJC_CLASS_$_WeMoDiscoveryManager", referenced from:

  objc-class-ref in LightControlViewController.o

ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

接下来我尝试禁用 arm64 假设库不是 64 位(如果我错了，请纠正我)

不知道从哪里开始，我怀疑该库已经过时并且不适用于 armv7/7s(它也不会在模拟器下的 i386 中构建)但是如果有人对此或任何想法有任何运气，任何事情都将不胜感激。

Answer 1

这是我从这个问题中恢复的解决方案。

将文件夹 -iphonesos 中提供的库包含到您的项目中。

将以下框架添加到 Project。

1. libxml2.dylib
2. CFNetwork.framework
3. MobileCoreServices.framework
4. Security.framework
5. SystemConfiguration.framework

然后转到您的build设置并搜索架构。

通过单击其他...添加新值并添加 $(ARCHS_STANDARD_32_BIT)

如果您也可以选择，$(ARCHS_STANDARD)表示 Standard architectures (armv7, armv7s)

构建项目，您将摆脱所有链接器错误。
