iOS中出现（linker command failed with exit code 1）错误总结

第三方库报错

开发中难免需要导入第三方库，导库之后编译报错:

Undefined symbols for architecture armv7:  
  "_OBJC_CLASS_$_MyPageLogViewController", referenced from:  
      objc-class-ref in BaiduMobStatAppDelegate.o  
ld: symbol(s) not found for architecture armv7  
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

解决方法是在Build settings->Linking->Other Linker Flags中添加-ObjC如图所示:

添加-ObjC

静态库报错

导入第三方静态库.a的时候，有的时候也会报错：

Undefined symbols for architecture armv7:  
  "_OBJC_CLASS_$_BaiduMobStat", referenced from:  
      objc-class-ref in libLECLivePlayerUISDK.o  
      objc-class-ref in libLECLivePlayerSDK.o  
ld: symbol(s) not found for architecture armv7  
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

这种情况下先看下是否是导入的库重复了，或者是没有引用，如果是导库冲突了，删除按照官方文档重新导入，如果是没有引用，在Build settings->Search Path->Library Search Paths中引入静态库路径,如图:
