xcode，在iPhone Simulator 64bit上编译时出错

Question

I creted application with iOS SDK 6.1. Everything works fine, but today I checked my app on iOS Simulator for iPhone 64bit. The following screen shows errors at compile.

For example,

Undefined symbols for architecture x86_64:
"_CFRelease", referenced from: 
-[Reachability dealloc] in Reachability.o

or

"_CFRunLoopGetCurrent", referenced from:
  -[Reachability startNotifier] in Reachability.o
  -[Reachability stopNotifier] in Reachability.o

This Reachability class I used in another project and works on iPhone Sim 64b. Can anyone help me with this ?

Answer 1

Your code would be in arc and file you have added has nonarc code. remove dealloc and check you have added all framework added which required for rechability class.
