我试图在我的设备上运行VAFieldTest应用程序，但应用程序崩溃在此行_CTServerConnectionRegisterForNotification。我怎样才能解决这个崩溃？如何解决在VAFieldTest应用程序中发生_CTServerConnectionRegisterForNotification崩溃
这里是我所传递的参数：
CTServerConnectionRef conn;
void register_notification(){
if (!mach_port || !conn) return;
void *libHandle = dlopen("/System/Library/Frameworks/CoreTelephony.framework/CoreTelephony", RTLD_LOCAL | RTLD_LAZY);
void *kCTCellMonitorUpdateNotification = dlsym(libHandle, "kCTIndicatorsSignalStrengthNotification");
if(kCTCellMonitorUpdateNotification== NULL) NSLog(@"Could not find kCTCellMonitorUpdateNotification");
int x = 0; //placehoder for callback
_CTServerConnectionRegisterForNotification(conn,kCTCellMonitorUpdateNotification,(void*)&x);
}
这里是崩溃报告：

用错误日志编辑你的问题。 – Tirth 2013-03-15 05:38:54
@iHungry我已经启用僵尸，即使没有打印在控制台。它在_CTServerConnectionRegisterForNotification行中表示EXC_BAD_ACCESS。我附上了上面的截图。你能检查一下吗？ – Dee 2013-03-15 05:57:21
@iAmbitious用错误日志更新了我的问题。你现在可以验证它吗？ – Dee 2013-03-25 06:02:58
