First, Apple obtains the longitude and latitude [Plain]If ([CLLocationManager locationServicesEnabled]) {// determines whether the mobile phone can be located.LocationManager = [[CLLocationManager alloc] init]; // initialize the Location Manager[LocationManager setDelegate: self];[LocationManager setDesiredAccuracy: kCLLocationAccuracyBest]; // sets the precision

Get the current phone address, and then convert from latitude and longitude to detailed address (including: Country name-Country code, province, city, street name, postal code, etc.). 1: Get current phone latitude and longitude @implementation currentlocation @synthesize Locationmanager; @synthesize Target,callback;

General idea: Based on the given latitude and longitude (Lat, LNG), find the four positions in the upper left corner (left_top), upper right corner (right_top), lower left corner (left_bottom), and lower right corner (right_bottom. All the ranges in this region are near this point.Reference: http://blog.charlee.li/location-search/ package com.show.common.util;pub
