iOS gets the latest ways to get the network (try it on yourself)

typedef enum {network_type_none= 0, network_type_wifi= 1, network_type_3g= 2, network_type_2g= 3,
}network_type;
Then by getting the sign of the network type above the phone signal bar
+ (int) Datanetworktypefromstatusbar {   uiapplication *app = [uiapplicationsharedapplication];   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 netType = Network_type_none; NSNumber * num = [Datanetworkitemview valueforkey:@ "Datanetworktype"];if (num = = nil) {       NetType = network_type_none;< C10/>}else{int n = [num intvalue];if (n = = 0) {           netType = Network_type_none;       } ElseIf (n = = 1) {           netType = network_type_2g;       } ElseIf (n = = 2) {           netType = network_type_3g;       } else{           netType = Network_type_wifi;       }   } return netType;}
If you find the problem, please timely inform, thank you!
