Is there a way to pick the network bearer in iOS?

Question

I know that on Android there is an API to specify which network bearer to use (WiFi vs cellular vs VPN).

Does iOS have an equivalent facility/API/capability? I checked the documentation but it seems that it such API is not publicly available.

No, there isn't any way for an iOS app to select which type of network data is sent over. The sandbox keeps you from doing that.

If it's a problem like you're downloading a large file and don't want to do it over a user's cellular data connection (as a user, thank you!), you could use Apple's Reachability class to see what the current data connection is. This other answer shows how to do that:

Reachability *reachability = [Reachability reachabilityForInternetConnection];
[reachability startNotifier];

NetworkStatus status = [reachability currentReachabilityStatus];

if(status == NotReachable) 
{
    //No internet
}
else if (status == ReachableViaWiFi)
{
    //WiFi
}
else if (status == ReachableViaWWAN) 
{
    //3G
}
