IOS编译报错：objc-class-ref in AppDelegate.o之解决方案 Xcode7

Undefined symbols for architecture x86_64:

"_OBJC_CLASS_$_QQApiInterface", referenced from:

objc-class-ref in AppDelegate.o

"_OBJC_CLASS_$_ShareSDK", referenced from:

objc-class-ref in AppDelegate.o

objc-class-ref in RecipeDetailViewController.o

objc-class-ref in showViewController.o

objc-class-ref in video_show.o

"_OBJC_CLASS_$_TencentOAuth", referenced from:

objc-class-ref in AppDelegate.o

"_OBJC_CLASS_$_WXApi", referenced from:

objc-class-ref in AppDelegate.o

1.把1.选中Targets—>Build Settings—>Architectures。

把build active architectures only 改为 NO。

2. 把最下面的Valid Architectures中的arm64参数删掉就可以了

或者：

双击Architectures，选择other，删除$(ARCH_STANDARD)，然后增加armv7和armv7s（写上：$(ARCHS_STANDARD_32_BIT)）。

3.clean 再build。

结果设置如下图：

目前设置完成后，问题顺利解决，大家有更好的解决方案，欢迎讨论！
