iOS: Can I manually associate wifi network with geographic location?
问题 Is it possible to make the phone to "know" that a specific wifi network is at specific geographic location? if (answer == YES) { than how? } else { can the phone figure this out by himself? } Another similar question: is there any way to start monitor a region with accuracy of ~100m but telling the CLLocationManager to use only by wifi networks and cellular antenas? Because I don't want to power up the GPS no matter what... Thanks! 回答1: iPhone positioning sucks and there is nothing you can do
