iOS 4.3上的libobjc.A.dylib编译错误

Question

我在iOS模拟器4.3中遇到编译错误我实际上无法弄明白,我得到的错误是:

dyld: lazy symbol binding failed: Symbol not found: _objc_retain
  Referenced from: /Users/ben/Library/Application Support/iPhone Simulator/4.3.2/Applications/75915A97-7C3D-489A-B7B0-7B6895A4B584/AppName.app/AppName
  Expected in: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/usr/lib/libobjc.A.dylib

dyld: Symbol not found: _objc_retain

  Expected in: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/usr/lib/libobjc.A.dylib

注:
该库被引用(libobjc.A.dylib)实际上是在"预期的地方"的代码工作正常的iOS5的设备上,并在iOS5的模拟器.
