[error] EXC_BAD_ACCESS (code=2, address=0x7ffee3638ff8)

when i just write a function to assign nsstring to my class’s nsstring ,
xcode raise EXC_BAD_ACCESS (code=2, address=0x7ffee3638ff8)!

i trace the code, found it will run into infinite loop
at self.message = Message.
after few time the program will crash.

reason:
if you use dot . in setter function , objective-c will raise infinite loop!

Resolution: move message from Company1Base to Company1
