?接第一步的操作，獲取到地址信息經緯度后，我們可以對其進行解碼，解碼采用的CLGeocoder這個類，使用方式如下：

1、在ViewControlelr.m文件中聲明一個CLGeocoder的屬性，給頁面加一個button，然后在處理方法中，對上一篇獲取的地址坐標進行解碼，

code如下：

// // ViewController.m // LBS_001_CLLocationManager // // Created by liqun on 13-7-17. // Copyright (c) 2013年 Block Cheng. All rights reserved. //#import "ViewController.h" #import <CoreLocation/CoreLocation.h> #import <MapKit/MapKit.h> @interface ViewController ()<CLLocationManagerDelegate,MKMapViewDelegate>{ } @property (nonatomic,retain)CLLocationManager* locationManager; @property (nonatomic,retain)CLLocation* location; @property (nonatomic, retain) CLGeocoder *myGeocoder; @end@implementation ViewController-(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {_locationManager = [[CLLocationManager alloc] init];}return self; } - (void)dealloc {self.locationManager = nil;self.location = nil;self.myGeocoder = nil;[super dealloc]; } - (void)viewDidLoad {[super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.//delegateself.locationManager.delegate = self;//The desired location accuracy. self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;//Specifies the minimum update distance in meters.self.locationManager.distanceFilter = kCLDistanceFilterNone;self.locationManager.purpose =@"To provide functionality based on user's current location.";[self.locationManager startUpdatingLocation];UIButton *addBt = [UIButton buttonWithType:UIButtonTypeRoundedRect];addBt.frame = CGRectMake(0, 00, 320, 50);[addBt setTitle:@"locationMe" forState:UIControlStateNormal];[addBt addTarget:self action:@selector(handleLocationMe:) forControlEvents:UIControlEventTouchUpInside];[self.view addSubview:addBt];self.myGeocoder = [[CLGeocoder alloc] init]; }- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {NSLog(@"didChangeAuthorizationStatus---%u",status); }- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {NSLog(@"didChangeAuthorizationStatus----%@",error); }- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {UIAlertView* av = [[UIAlertView alloc] initWithTitle:@"update" message:[NSString stringWithFormat:@"didUpdateToLocation: newLocation: %@ old:%@",newLocation,oldLocation] delegate:nil cancelButtonTitle:@"cancel" otherButtonTitles:@"ok", nil];[av show];[av release];self.location = newLocation;NSLog(@"didUpdateToLocation: newLocation: %@",newLocation); }- (void)didReceiveMemoryWarning {[super didReceiveMemoryWarning];// Dispose of any resources that can be recreated. }-(IBAction)handleLocationMe:(id)sender {[self.myGeocoderreverseGeocodeLocation:self.location completionHandler:^(NSArray *placemarks, NSError *error) {if (error == nil &&[placemarks count] > 0){CLPlacemark *placemark = [placemarks objectAtIndex:0];/* We received the results */NSLog(@"Country = %@", placemark.country);NSLog(@"Postal Code = %@", placemark.postalCode);NSLog(@"Locality = %@", placemark.locality);NSLog(@"dic = %@", placemark.addressDictionary );NSLog(@"dic FormattedAddressLines= %@", [placemark.addressDictionary objectForKey:@"FormattedAddressLines"]);NSLog(@"dic Name = %@", [placemark.addressDictionary objectForKey:@"Name"]);NSLog(@"dic State = %@", [placemark.addressDictionary objectForKey:@"State"]);NSLog(@"dic Street = %@", [placemark.addressDictionary objectForKey:@"Street"]);NSLog(@"dic SubLocality= %@", [placemark.addressDictionary objectForKey:@"SubLocality"]);NSLog(@"dic SubThoroughfare= %@", [placemark.addressDictionary objectForKey:@"SubThoroughfare"]);NSLog(@"dic Thoroughfare = %@", [placemark.addressDictionary objectForKey:@"Thoroughfare"]);}else if (error == nil &&[placemarks count] == 0){NSLog(@"No results were returned.");}else if (error != nil){NSLog(@"An error occurred = %@", error);}}]; } @end 日志輸出如下：
