tapkulibrary fail to archive in xcode 5.1.1

[flyingfan76]

I following the document to import tapkulibrary in my project. The whole project can be successfully build and run on simulator and real device until the last phase "archive". During the archive phase, I always got the following errors report on "UIView+TKCategory.m" file.

"Semantic issue: Assignment to readonly property"

• (void) roundOffFrame{
  self.frame = CGRectMake(roundf(CGRectGetMinX(self.frame)), roundf(CGRectGetMinY(self.frame)), roundf(CGRectGetWidth(self.frame)), roundf(CGRectGetHeight(self.frame)));
  }

If I comment out this statement. I would get many other similar issues on alterview and calenderview file.
Any suggestion on how to solve this issue. Btw I am using ios SDK 7.1

Thanks
