Common IOS undefined symbols error

Link Error:

Undefined symbols for architecture i386:

“operator new(unsigned long)”, referenced from:
-[CkoMailMan init] in libchilkatIos.a(CkoMailMan.o)
“operator delete(void*)”, referenced from:
-[CkoMailMan init] in libchilkatIos.a(CkoMailMan.o)

Solution:
The Chilkat internals are written in C++. Therefore, your Objective-C application will need to link against the C++ runtime libraries. The easiest way to do it is to include an empty source file with the file extension “cpp” in your app target.
