How to determine whether user is on Edge or 3G on iPhone

Question

Though it is relatively straightforward to determine if an iPhone is on Wifi or a data network programmatically in your application, I can\'t figure out a way to determine i

Answer 1

Try checking it from the status bar:

UIApplication *app = [UIApplication sharedApplication];
NSArray *subviews = [[[app valueForKey:@"statusBar"] valueForKey:@"foregroundView"]    subviews];
NSNumber *dataNetworkItemView = nil;

for (id subview in subviews) {
    if([subview isKindOfClass:[NSClassFromString(@"UIStatusBarDataNetworkItemView") class]]) {
        dataNetworkItemView = subview;
        break;
    }
}
int connectivity;
connectivity =  [dataNetworkItemView valueForKey:@"dataNetworkType"];

And the value keys I've found so far:

0 = No wifi or cellular

1 = 2G and earlier? (not confirmed)

2 = 3G? (not yet confirmed)

3 = 4G

4 = LTE

5 = Wifi
