尝试安装Google登录时出现链接错误

Question

我正在尝试将Google登录集成到我的iOS应用中，但在执行此操作时我收到了以下错误。

有没有解决方案可以消除以下错误？

Undefined symbols for architecture armv7: "_inflate", referenced from: l002 in GoogleSignIn(GTMNSData+zlib.o) "_deflate", referenced from: l001 in GoogleSignIn(GTMNSData+zlib.o) "_inflateEnd", referenced from: l002 in GoogleSignIn(GTMNSData+zlib.o) "deflateInit2", referenced from: l001 in GoogleSignIn(GTMNSData+zlib.o) "inflateInit2", referenced from: l002 in GoogleSignIn(GTMNSData+zlib.o) "_deflateEnd", referenced from: l001 in GoogleSignIn(GTMNSData+zlib.o) ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

您可以在下面的步骤休耕

1. 去盖设置/链接/其它链接器标记，并添加“-ObjC”不带引号。这假设你正在使用一些“头文件

   文件”来映射谷歌框架和Swift方法。

2. 前往构建阶段>链接二进制与Librairies> +>添加其它的去脱/ usr/lib目录，选择 “libz.dylib”

3. 编译

Answer 2

这是很常见的错误，并没有任何具体的解决方案。虽然可能是以下解决方法可以帮助你：

1. If you are not using cocoa-pods use them to add new repos.

2. Check that you haven't imported .m instead of .h .

3. Check you haven't add two frameworks accidenlty.

4. Remove -ObjC Linker flag from `-otherLinkerFlags'

5. Sometimes using older version of sdk may solve the problem.

6. Navigate to YourProject--Build Phases and check you haven't added one file more than once. And also any Link Binary and Libraries are not missing from there.

添加-ObjC和libz解决了我的问题。但在我的情况下，我找不到路径/usr/bin中的libz.dylib。我在iOS 9.3文件夹中使用了libz.tbd，而且它也可以正常工作，并解决了这些相同的错误。
