iOS example build 不成功

[SenorSamuel]

"How to build"里面没有更新

Run tools/ios-token-v2-build.sh. Set the right DIR in tools/ios-token-v2-build.sh. After running this shell, the lib files will be compiled and copied to the directory you set before.

已经没有这个脚本了

现在是: ios-framework-build.sh ios-example-build.sh 这两个,请问应该怎么编译?
