Recently in doing a bus query project, you need to locate the current location in order to conduct a nearby site query, and you share how to obtain their current position latitude and longitude First add the Corelocation.framework library: Reference header file and declare cllocationmanagerdelegate agent: Next, declare the variables you want to use: @property

. When the user agrees to share the user's location with the browser, the map automatically adjusts the window center to that location.The Leaflet.js has two interfaces Locationerror is the callback function that is called after the local address failure is obtained, and Locationfound is the callback that gets the successful local address.Make sure that all the code is before creating div tags and referencing leaflet.js. There should be no problem, yo

C # access Baidu map via network address in the background to retrieve the longitude and latitude of the current map, and deserialize the retrieved string in complicated Json format (Newtonsoft. Json ), Directly go to the Code: explanations are all in the code The accesskey must be applied for on Baidu map. When you apply for an accesskey, you only need to enter * For the render attribute.

This is a good example, directly affixed to the code, first of all to know the latitude value, longitude value /** * @desc calculates the distance * @param float $lat latitude value based on the longitude of two points * @param float $lng Longitude value * /function

This article mainly introduces how PHP calculates the distance based on the longitude and latitude between two points. The code is very simple, but it is very practical. if you need it, you can refer to this as a good example and paste the code directly, first, you must know the latitude and longitude values. /***
