iOS 8 CoreBluetooth不推荐使用RSSI方法 [英] iOS 8 CoreBluetooth deprecated RSSI methods
问题描述
因此，通过阅读 CBPeripheralDelegate 文档，似乎 RSSI 和 peripheralDidUpdateRSSI：错误：已被iOS 8弃用。
So from reading the CBPeripheralDelegate documentation, it appears that RSSI and peripheralDidUpdateRSSI:error: were deprecated with iOS 8.
我注意到我的信号强度指示器不再更新，所以我做了一些研究并发现了新方法（ [CBPeripheralDelegate peripheral：didReadRSSI：error：] ）在调用 readRSSI 方法之后可能异步调用。不幸的是，即使我确实将父类设置为CBPeripheral委托，这个方法似乎也没有被回调。
I noticed that my signal strength indicator was no longer being updated, so I did some research and found a new method ([CBPeripheralDelegate peripheral:didReadRSSI:error:]) that supposedly get called back asynchronously after calling the readRSSI method. Unfortunately, this method does not seem to get called back either, even though I did set the parent class as the CBPeripheral delegate.
还有其他人遇到iOS 8 CoreBluetooth更新问题吗？
Has anyone else had issues with the iOS 8 CoreBluetooth updates?
推荐答案
在Apple开发者论坛上已经发布了一个已知问题，我也有一个开放的雷达。
There is a known issue that has been posted about this on the Apple Developer forums to which I have an open radar as well.
问题似乎是初始连接到外围设备后，在iOS 8上永远不会调用新的回调方法 peripheral：didReadRSSI：error：。我发现的唯一解决方案是通过打开/关闭手机或重新启动手机来重置手机上的蓝牙。
The issue seems to be that the new callback method peripheral:didReadRSSI:error: is never called on iOS 8 specifically after the initial connection is made to a peripheral. The only resolution I have found is to reset bluetooth on your phone by turning it on/off or restarting the phone.
刚刚测试了我的示例8.2发布，我不再看到从未被调用的新iOS 8委托方法的任何问题。我按照8.2版本标记了我的雷达。
Just tested my example that was displaying this issue with the current 8.2 release and I am no longer seeing any issues with the new iOS 8 delegate method never being called. I am marking my radar as resolved per the 8.2 release.
