Is there any way to get an iPhone's GPS signal strength? I'd like to make some kind of display like this:
- 如果GPS = 0或无信号：color = red / Poor或No
- 如果GPS => 140 m信号：颜色橙色/公平信号
- 或优异信号
推荐答案
不存在用于检查GPS信号强度的公共API，听起来像这是你真正寻找反正。您绝对可以检查由CoreLocation返回的位置的准确性。
No public API exists for checking GPS signal strength but it doesn't sound like that is what you are really looking for anyway. You absolutely can check the accuracy of the locations returned by CoreLocation.
查看 CLLocation ，它具有 horizontalAccuracy 和 verticalAccuracy 属性，表示设备相对于位置锁定的准确程度。
Look at CLLocation, it has horizontalAccuracy and verticalAccuracy properties which indicate how accurate the device believes that location fix to be.
