我正在寻找一种从设备 GPS 获取 GPRMC 信息的方法.

I 'm looking for a way to obtain the GPRMC info from device GPS.

有没有可能?

推荐答案

不，不可能.首先 GPRMC 是来自基于文本的 NMEA 协议的消息，它是一个没有很好定义的协议，每个芯片制造商对它的解释不同.对于大多数专业设备，使用芯片制造商提供的二进制协议.即使 Apple 在内部使用 NMEA Protokoll 与芯片通信，您也无法访问该消息.

No, it is not possible. First GPRMC is a message from the text based NMEA protocoll, which is a not well defined protocoll, each chip manufacturer interprets it differently. Therfore most professional devices, use the binary protocoll from the Chip manufacturer. And even when Apple woud internally use the NMEA Protokoll to communicate with the chip, you would not have any access to that messages.

但是 GPRMC 消息的数据在 CLLocationManager 下发的 CLLocation 中是可用的.

However the data of the GPRMC message is available in CLLocation delivered by CLLocationManager.

让我们看看RMC的属性:
