倾斜Sphero的示例并更新UISlider？

Question

我有1个滑块的视图。我想把Sphero球拿在手里，所以当球向左或向右倾斜时，滑块向左或向右移动。

最好的示范项目是什么？

Answer 1

你应该看看其中一个：

• https://github.com/orbotix/Sphero-iOS-SDK/tree/master/samples/StreamingAnimation
• https://github.com/orbotix/Sphero-iOS-SDK/tree/master/samples/SensorStreaming

Answer 2

我会使用https://github.com/orbotix/Sphero-iOS-SDK/tree/master/samples/SensorStreaming

在handleAsyncData内添加对滑块的引用：

- (void)handleAsyncData:(RKDeviceAsyncData *)asyncData
{
   if ([asyncData isKindOfClass:[RKDeviceSensorsAsyncData class]]) {
       packetCounter++;
       if( packetCounter > (TOTAL_PACKET_COUNT-PACKET_COUNT_THRESHOLD)) {
           [self sendSetDataStreamingCommand];
       }

       // Received sensor data, so display it to the user.
       RKDeviceSensorsAsyncData *sensorsAsyncData = (RKDeviceSensorsAsyncData *)asyncData;
       RKDeviceSensorsData *sensorsData = [sensorsAsyncData.dataFrames lastObject];
       RKAccelerometerData *accelerometerData = sensorsData.accelerometerData;
       RKAttitudeData *attitudeData = sensorsData.attitudeData;

        // this Assumes your Slider has been hooked up in the Interface Builder
        // With float values between 1.0 and 0.0
       [MyAccelerometerSlider setFloatValue:accelerometerData.acceleration.x];
       // You could also set it to the Roll value which is better for controller stuff
       [MyOtherSlider setDoubleValue:attitudeData.roll];
   }
}

只需将要监视的轴从x更改为y或z。您还可以使用Streaming示例中的其他流功能。即。海拔高度和四元数。
