本文介绍了在iOS中获取用户定位的方法，包括设置info.plist文件，使用系统定位服务以及集成百度地图SDK获取经纬度。同时，文章涵盖了处理定位权限提示、更新位置信息以及如何获取城市名的细节。

1. 首先在info.plist文件中设置

NSLocationAlwaysUsageDescription string 我们需要您当前所在位置喔 //始终获取

NSLocationWhenInUseUsageDescription string 我们需要您当前所在位置喔 //在使用应用期间

2. 设置系统和百度的定位方式

1）系统定位

//头文件中加入delegate

@property (nonatomic,retain)CLLocationManager *locationManager;

//.m文件中创建

//iOS自带定位，获取经纬度

- (void)createLocationManage

{

self.locationManager = [[CLLocationManager alloc]init];

self.locationManager.delegate = self;

self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;

self.locationManager.distanceFilter = 10;

[CLLocationManager locationServicesEnabled];

if ([[[UIDevice currentDevice] systemVersion] floatValue]>=8.0) {

[self.locationManager requestAlwaysAuthorization];//如果想让ios8获取当前地址，需要添加此代码

}

[self.locationManager startUpdatingLocation];

if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied) {

NSLog(@"定位不可用");

[self shopsList:@" " setLat:@" "];

}

#pragma mark CLLocationManager

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations

{

CLLocation *currLocation = [locations lastObject];

localLongitude = currLocation.coordinate.longitude;

localLatitude = currLocation.coordinate.latitude;

NSString *localLongitudeStr = [NSString stringWithFormat:@"%f",localLongitude]; //经度

NSString *localLatitudeStr = [NSString stringWithFormat:@"%f",localLatitude]; //维度

//将经纬度保存到SharedInfo中

SharedInfo *sharedInfo = [SharedInfo sharedDataInfo];

sharedInfo.localLongitude = localLongitudeStr;

sharedInfo.localLatitude = localLatitudeStr;

//NSLog(@"localLongitudeStr:%@",localLongitudeStr);

//NSLog(@"localLatitudeStr:%@",localLatitudeStr);

[self.locationManager stopUpdatingLocation];

//获取当前城市名

CLGeocoder *geocoder = [[CLGeocoder alloc]init];

[geocoder reverseGeocodeLocation:currLocation completionHandler:^(NSArray *placemarks, NSError *error) {

for (CLPlacemark *place in placemarks) {

//NSLog(@"name,%@",place.name); //位置

//NSLog(@"thoroughfare,%@",place.thoroughfare); //街道

//NSLog(@"subThoroughfare,%@",place.subThoroughfare); //子街道

if (place != nil) {

NSString *tempCity = place.locality;

_currentLocation = [tempCity stringByReplacingOccurrencesOfString:@"市" withString:@""];

sharedInfo.currentCity = _currentLocation;

if (sharedInfo.currentCity.length > 0) {

if (sharedInfo.subCityName.length > 0) {

NSString *cityNames = [NSString stringWithFormat:@"%@-%@",sharedInfo.currentCity,sharedInfo.subCityName];

[self createLeftBtn:cityNames];

}else{

[self createLeftBtn:sharedInfo.currentCity];

}

[self getAllCityList];

[self shopsList:localLongitudeStr setLat:localLatitudeStr];

//NSLog(@"locality,%@",_currentLocation); //市

return;

}

//NSLog(@"subLocality,%@",place.subLocality); //区

//NSLog(@"country,%@",place.country); //国家

}

}];

}

//根据错误号，如果不允许定位的时候处理方法

- (void)locationManager: (CLLocationManager *)manager

didFailWithError: (NSError *)error {

[manager stopUpdatingLocation];

if ([error code] == 1) {

if (IS_IOS7) {

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"定位服务未开启" message:@"定位服务已被关闭，请前往设置页面打开" delegate:self cancelButtonTitle:@"暂不" otherButtonTitles:nil, nil];

alertView.tag = 1101;

[alertView show];

}else if (IS_IOS8){

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"定位服务未开启" message:@"定位服务已被关闭，请前往设置页面打开" delegate:self cancelButtonTitle:@"暂不" otherButtonTitles:@"去设置", nil];

alertView.tag = 1100;

[alertView show];

}

2）百度定位

//百度地图获取经纬度

- (void)createBaiDuMapView

{

CLAuthorizationStatus status = [CLLocationManager authorizationStatus];

if (IS_IOS7) {

if (kCLAuthorizationStatusDenied == status || kCLAuthorizationStatusRestricted == status) {

alertView.tag = 1101;

[alertView show];

}

}else if (IS_IOS8){

if (kCLAuthorizationStatusDenied == status || kCLAuthorizationStatusRestricted == status) {

alertView.tag = 1100;

[alertView show];

}

[self initMBProgress:@"数据加载中..."];

//设置定位精确度，默认：kCLLocationAccuracyBest

[BMKLocationService setLocationDesiredAccuracy:kCLLocationAccuracyBest];

//指定最小距离更新(米)，默认：kCLDistanceFilterNone

[BMKLocationService setLocationDistanceFilter:100.f]; //当距离超过100米的时候就更新一次地图

//初始化BMKLocationService

_locService = [[BMKLocationService alloc]init];

_locService.delegate = self;

//启动LocationService

[_locService startUserLocationService];

}

#pragma mark -- BaiDuMapDelegate

//处理位置坐标更新

- (void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation

{

//NSLog(@"didUpdateUserLocation lat %f,long %f",userLocation.location.coordinate.latitude,userLocation.location.coordinate.longitude);

//这里通过百度和系统自带的定位方式来获取经纬度，如果系统没有获取到，就获取百度的

localLongitude = userLocation.location.coordinate.longitude;

localLatitude = userLocation.location.coordinate.latitude;

NSString *localLongitudeStr = [NSString stringWithFormat:@"%f",localLongitude]; //经度

NSString *localLatitudeStr = [NSString stringWithFormat:@"%f",localLatitude]; //维度

//将经纬度保存到SharedInfo中

SharedInfo *sharedInfo = [SharedInfo sharedDataInfo];

sharedInfo.localLongitude = localLongitudeStr;

sharedInfo.localLatitude = localLatitudeStr;

// 保存 Device 的现语言 (英语法语)

NSMutableArray *userDefaultLanguages = [[NSUserDefaults standardUserDefaults]

objectForKey:@"AppleLanguages"];

// 强制成简体中文

[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:@"zh-hans",nil]

forKey:@"AppleLanguages"];

CLGeocoder *Geocoder=[[CLGeocoder alloc]init];//CLGeocoder用法参加之前博客

CLGeocodeCompletionHandler handler = ^(NSArray *place, NSError *error) {

for (CLPlacemark *placemark in place) {

cityStr=placemark.name;

cityName=placemark.locality;

NSLog(@"city %@",placemark.name); //获取街道地址

NSLog(@"cityName %@",placemark.locality);//获取城市名

NSString *tempCity = placemark.locality;

_currentLocation = [tempCity stringByReplacingOccurrencesOfString:@"市市辖区" withString:@""];

_currentLocation = [tempCity stringByReplacingOccurrencesOfString:@"市" withString:@""];

sharedInfo.currentCity = _currentLocation;

if (sharedInfo.currentCity.length > 0) {

if (sharedInfo.subCityName.length > 0) {

NSString *cityNames = [NSString stringWithFormat:@"%@-%@",sharedInfo.currentCity,sharedInfo.subCityName];

[self createLeftBtn:cityNames];

}else{

[self createLeftBtn:sharedInfo.currentCity];

}

sharedInfo.cityName = placemark.name;

[self getAllCityList];

[self shopsList:localLongitudeStr setLat:localLatitudeStr];

}

};

CLLocation *loc = [[CLLocation alloc] initWithLatitude:userLocation.location.coordinate.latitude longitude:userLocation.location.coordinate.longitude];
