-(NSString *)getNetWorkStates{        UIApplication *app = [UIApplication sharedApplication];    NSArray *children = [[[app valueForKeyPath:@"statusBar"]valueForKeyPath:@"foregroundView"]subviews];    NSString *state = nil;    int netType = 0;    //擷取到網路返回碼    for (id child in children) {        if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) {            //擷取到狀態列            netType = [[child valueForKeyPath:@"dataNetworkType"]intValue];                        switch (netType) {                case 0:                    state = @"無網路";                    //無網模式                    break;                case 1:                    state = @"2G";                    break;                case 2:                    state = @"3G";                    break;                case 3:                    state = @"4G";                    break;                case 5:                {                    state = @"WIFI";                }                    break;                default:                    break;            }        }    }    //根據狀態選擇    return state;}
