推荐答案

检查手机网络使用此

- (bool) hasCellular {
    struct ifaddrs * addrs;
    const struct ifaddrs * cursor;
    bool found = false;
    if (getifaddrs(&addrs) == 0) {
        cursor = addrs;
        while (cursor != NULL) {
            NSString *name = [NSString stringWithUTF8String:cursor->ifa_name];
                if ([name isEqualToString:@"pdp_ip0"]) 
                    found = true;
            }
            cursor = cursor->ifa_next;
        }
        freeifaddrs(addrs);
    }
    return found;
}
