How to return BOOL when checking internet connection in XCODE

I want to be able to check for internet connectivity when my View loads. To predetermine the contents of my view.

I have the following viewDidLoad method:

- (void)viewDidLoad {
    [super viewDidLoad];

    if(![self hasInternetConnection]){
        NSLog(@"SHOW ORIGINAL DOC");
    }
    else{
        NSLog(@"SHOW NEW DOC");
    }
}

And I have a method called hasInternetConnection as follows:

- (BOOL)hasInternetConnection{

    NSLog(@"Starting connection test");

    internetReachableFoo = [Reachability reachabilityWithHostname:@"www.google.com"];

    // Internet is reachable
    internetReachableFoo.reachableBlock = ^(Reachability*reach){
        // Update the UI on the main thread
        dispatch_async(dispatch_get_main_queue(), ^{
            NSLog(@"We have internet");
            return YES;
        });
    };

    // Internet is not reachable
    internetReachableFoo.unreachableBlock = ^(Reachability*reach){
        // Update the UI on the main thread
        dispatch_async(dispatch_get_main_queue(), ^{
            NSLog(@"We do not have internet");
            return NO;
        });
    };

    [internetReachableFoo startNotifier];

}

I don't want to use the deprecated Apple reachibility class using:

NetworkStatus internetStatus = [internetReachable currentReachabilityStatus];

How can I change the code in -(BOOL)hasInternetConnection to efficiently return a boolean for my method to work?
