Is there a (legal) way to capture the ENTIRE screen under iOS?

Question

I\'ve tried several techniques to capture a screenshot of an app from within that app. None of the techniques appear to capture the status bar -- it ends up being black.

Your actual issue, determining if a network interface is active, can be resolved with BSD networking functions. BEHOLD.

#include 
#include 
#include 

BOOL IsNICTurnedOn(const char *nicName) {
    BOOL result = NO;

    struct ifaddrs *addrs = NULL;
    if (0 == getifaddrs(&addrs)) {
        for (struct ifaddrs *addr = addrs; addr != NULL; addr = addr->ifa_next) {
            if (0 == strcmp(addr->ifa_name, nicName)) {
                result = (0 != (addr->ifa_flags & (IFF_UP | IFF_RUNNING)));
                break;
            }
        }
        freeifaddrs(addrs);
    }

    return result;
}

To use this function:

BOOL isWWANEnabled = IsNICTurnedOn("pdp_ip0");
BOOL isWiFiEnabled = IsNICTurnedOn("en0");
