[viking2009]

fix:

• (void)startLogging {
  [self stopLogging];

  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(networkRequestDidStart:) name:AFNetworkingOperationDidStartNotification object:nil];
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(networkRequestDidFinish:) name:AFNetworkingOperationDidFinishNotification object:nil];

if (defined(__IPHONE_OS_VERSION_MIN_REQUIRED) && __IPHONE_OS_VERSION_MIN_REQUIRED >= 70000) || (defined(__MAC_OS_X_VERSION_MIN_REQUIRED) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 1090)

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(networkRequestDidStart:) name:AFNetworkingTaskDidStartNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(networkRequestDidFinish:) name:AFNetworkingTaskDidFinishNotification object:nil];

endif

}
