ios6的程序报错了错误

ios6程序中显示了可达性错误,请明白的人帮我解决一下这个错误,不胜感激:

@implementation Reachability
 static void ReachabilityCallback(SCNetworkReachabilityRef target, SCNetworkReachabilityFlags flags, void* info)
 {
#pragma unused (target, flags)
NSCAssert(info != NULL, @"info was NULL in ReachabilityCallback");
NSCAssert([(NSObject*) info isKindOfClass: [Reachability class]], @"info was wrong class in ReachabilityCall9back");
//We're on the main RunLoop, so an NSAutoreleasePool is not necessary, but is added defensively
// in case someon uses the Reachablity object in a different thread.

Reachability* noteObject = (Reachability*) info;
// Post a notification to notify the client that the network reachability changed.
[[NSNotificationCenter defaultCenter] postNotificationName: kReachabilityChangedNotification object: noteObject];
  }

 - (BOOL) startNotifier
 {
BOOL retVal = NO;
SCNetworkReachabilityContext    context = {0, self, NULL, NULL, NULL};
if(SCNetworkReachabilitySetCallback(reachabilityRef, ReachabilityCallback, &context))
{
    if(SCNetworkReachabilityScheduleWithRunLoop(reachabilityRef, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode))
    {
        retVal = YES;
    }
}
return retVal;
  }

错误:

Cast of C pointer type 'void *' to Objective-C pointer type 'NSObject *' requires a bridged cast

原因是因为你想传的值不符合接受者的数据类型,一个是无数据类型void 一个是NSObject ,另外,无返回值类型void后面不加*
