Wifi callback not called in launch daemon - ios

Question

I want to write a launch daemon in iOS which connects to networks programmatically. For connecting to networks, I'm using Cykey's (David Murray) WifiManager app. Before writing the daemon it worked perfectly (I have used it in a springboard tweak) but now it doesn't scan for available networks (the method - (void)_scanDidFinishWithError:(int)error isn't been called). By logging, I found that the method _scan in DMNetWorksManager is called but the static void DMScanCallback(WiFiDeviceClientRef device, CFArrayRef results, int error, const void *token) isn't called. I think it's because of the runloop I have in the main.m file. Here is my code:
main.m:
int main (int argc, const char * argv[])
{
#autoreleasepool
{
// insert code here...
MSManager *server = [[MSManager alloc] init];
//start a timer so that the process does not exit.
/*NSDate *now = [[NSDate alloc] init];
NSTimer *timer = [[NSTimer alloc] initWithFireDate:now
interval:.01
target:server
selector:#selector(start)
userInfo:nil
repeats:NO];
NSRunLoop *runLoop = [NSRunLoop currentRunLoop];
[runLoop addTimer:timer forMode:NSDefaultRunLoopMode];
[runLoop run];*/
[server start];
CFRunLoopRun();
}
return 0;
}
and the start method in MSManager.m:
- (void)start
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(managerDidFinishScanning)
name:kDMNetworksManagerDidFinishScanning
object:nil];
//Some other code here....
}
- (void)managerDidFinishScanning
{
//Do some work here
}
NOTE: Iv'e used both CFRunloop and NSRunLoop (commented in the code) but none of them worked.
