ios - SocketScan 始终返回 100% 电池生命周期

Question

我每次都得到 100% 的结果...为什么(iOS/SocketScan API v.10.2.227)？ 这是我的代码:

-(void) onGetBatteryInfo:(ISktScanObject*)scanObj {

    SKTRESULT result=[[scanObj Msg]Result];
    if(SKTSUCCESS(result)){

        long batteryLevel = SKTBATTERY_GETCURLEVEL([[scanObj Property] getUlong]);
        NSLog(@"BatteryInfo %ld", batteryLevel);

        [self setBatteryLevel:batteryLevel];
        [self.tableView reloadData];

    } else {

        NSLog(@"ES-GetBatteryInfo set status returned the error %ld",result);
    }
}

谢谢， 标记

你能仔细检查以下...

在 viewDidLoad 中创建 ScanApiHelper 和一个计时器

if(ScanApi==nil) {
    ScanApi=[[ScanApiHelper alloc]init];
    [ScanApi setDelegate:self];
    [ScanApi open];
    ScanApiConsumer=[NSTimer scheduledTimerWithTimeInterval:.2 target:self selector:@selector(onTimer:) userInfo:nil repeats:YES];
}

您的计时器调用 doScanApiReceive

-(void)onTimer: (NSTimer*)theTimer{
    if(theTimer==ScanApiConsumer){
        [ScanApi doScanApiReceive];
    }
}

最后，在收到 onDeviceArrival 通知

之前，您不会查询电池电量

-(void)onDeviceArrival:(SKTRESULT)result device:(DeviceInfo*)deviceInfo {
    [ScanApi postGetBattery:deviceInfo Target:self Response:@selector(onGetBatteryInfo:)];
}
