Tapku Calendar integration errors

问题

I am working with a project and in that I want to integrateing a tapku calendar. I followed all the steps and integrated the calendar. But unfortunately I am getting the error due to which my build is failing again and again. The error is as below:

Undefined symbols for architecture x86_64:
      "_OBJC_CLASS_$_TKCalendarMonthView", referenced from:
          objc-class-ref in habitstatisticsViewController.o
    ld: symbol(s) not found for architecture x86_64
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

Set "Build Active Architechtures" to YES and make sure you have armv6 also within your valid architechtures along with arm64, armv7 and armv7s.
