cordova xcode link failed when refrence a 64bit-based library

i create a cordova project and add refrence to libwechatsdk.a (i upload the static library on http://pan.baidu.com/s/1sjmF7v3 ), when i build this project on xcode it throws link error:Undefined symbols for architecture Arm64.

i have tried to change the architecture settings but it doesn't work.

but if i use xcode to create a new cocoa simple application and add reference to this library, it works.

could you try my library and fix this problem for me?
it troubled me several days and our project has been seriously delayed.
