iOS获取当前网络状态

自己工作中用到的,在此记录一下,希望对大家有帮助。

- (NetWork_State_Type)getNetWorkStates{
    UIApplication *app = [UIApplication sharedApplication];
    NSArray *children = [[[app valueForKeyPath:@"statusBar"]valueForKeyPath:@"foregroundView"]subviews];
    NetWork_State_Type state = NetWork_State_NoNet;
    int netType = 0;
    //获取到网络返回码
    for (id child in children) {
        if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) {
            //获取到状态栏
            netType = [[child valueForKeyPath:@"dataNetworkType"]intValue];
            
            switch (netType) {
                case 0:
                    state = NetWork_State_NoNet;//无网络
                    break;
                case 1:
                    state = NetWork_State_2G;//2G
                    break;
                case 2:
                    state = NetWork_State_3G;//3G
                    break;
                case 3:
                    state = NetWork_State_4G;//4G
                    break;
                case 5:
                    state = NetWork_State_WiFi;//WiFi
                    break;
                case 6:
                    state = NetWork_State_HotSpot;//热点
                default:
                    break;
            }
        }
    }
    //根据状态选择
    return state;
}
