1、导入CoreLocation.h 头文件，然后声明专属的管理者对象，遵守代理CLLocationManagerDelegate
@property(nonatomic,strong)CLLocationManager *locationManager;
2、在viewdidload里面判断当前设备定位服务是否打开了，然后设置代理和精度
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
//初始化管理对象
CLLocationManager *locationManager = [[CLLocationManager alloc]init];
self.locationManager = locationManager;
//判断当前设备定位服务是否打开
if (![CLLocationManager locationServicesEnabled]) {
NSLog(@"设备尚未打开定位服务");
}
//判断当前设备版本大于iOS8以后的话执行里面的方法
if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0) {
[locationManager requestAlwaysAuthorization];
[locationManager requestWhenInUseAuthorization];
}
//设置代理
locationManager.delegate = self;
//设置定位精度
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
////设置定位的频率,这里我们设置精度为10,也就是10米定位一次
CLLocationDistance distance = 10;
//给精度赋值
locationManager.distanceFilter = distance;
//开始启动定位
[locationManager startUpdatingLocation];
}
3、配置info.plist文件，把下面两个属性加到文件中去，并且确定xcode是否联网
NSLocationAlwaysUsageDescription
NSLocationWhenInUseUsageDescription
4、实现代理方法进行定位当前的位置，获取到经纬度
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray*)locations
5、通过反地理编码进行中文的输出即可
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray* _Nullable placemarks, NSError * _Nullable error) {
6.不定位的时候应该停止定位
[self.locationManager stopUpdatingLocation];
//定位获取当前的经纬度
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray*)locations { CLLocation *location = [locations lastObject]; NSLog(@"%@",location.timestamp); CLLocationCoordinate2D coordinate = location.coordinate; NSLog(@"%f ,%f", coordinate.latitude,coordinate.longitude ); CLGeocoder *geocoder = [[CLGeocoder alloc]init]; [geocoder reverseGeocodeLocation:location completionHandler:^(NSArray* _Nullable placemarks, NSError * _Nullable error) {
if (error != nil || placemarks.count == 0) {
NSLog(@"%@",error);
return ;
}
for (CLPlacemark *placemark in placemarks) {
self.addressTextLabel.text = placemark.locality;
NSLog(@"%@",placemark.locality);
}
}];
[self.locationManager stopUpdatingLocation];
}
