- 不支持模拟器定位
- 可以获取当前的位置和经纬度
- 项目中有用到,拿来分享,大神勿喷,欢迎交流
#import <CoreLocation/CoreLocation.h>
@property (nonatomic, strong) CLLocationManager *locationManager;
<CLLocationManagerDelegate>
#pragma mark - 定位
- (void)startLocation {
if ([CLLocationManager locationServicesEnabled]) {
self.locationManager = [[CLLocationManager alloc]init];
self.locationManager.delegate = self;
//控制定位精度,越高耗电量越
self.locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
// 总是授权
[self.locationManager requestAlwaysAuthorization];
self.locationManager.distanceFilter = 10.0f;
[self.locationManager requestAlwaysAuthorization];
[self.locationManager startUpdatingLocation];
}
}```
- 要实现的几个代理方法
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
if ([error code] == kCLErrorDenied) {
NSLog(@"访问被拒绝");
}
if ([error code] == kCLErrorLocationUnknown) {
NSLog(@"无法获取位置信息");
}
}
//定位代理经纬度回调
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations {
CLLocation *newLocation = locations[0];
// 获取当前所在的城市名
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
//根据经纬度反向地理编译出地址信息
[geocoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *array, NSError *error){
if (array.count > 0){
CLPlacemark *placemark = [array objectAtIndex:0];
if (!city) {
//四大直辖市的城市信息无法通过locality获得，只能通过获取省份的方法来获得（如果city为空，则可知为直辖市）
city = placemark.administrativeArea;
}
// [self httpGetWeather:city];
}
else if (error == nil && [array count] == 0)
{
NSLog(@"No results were returned.");
}
else if (error != nil)
{
NSLog(@"An error occurred = %@", error);
}
}];
//系统会一直更新数据，直到选择停止更新，因为我们只需要获 得一次经纬度即可，所以获取之后就停止更新
[manager stopUpdatingLocation];
}
- 获取到的信息就上面方法的placemark对象中,一下是部分属性,可以点进去查看
@property (nonatomic, readonly, copy, nullable) NSDictionary *addressDictionary;
@property (nonatomic, readonly, copy, nullable) NSString *name; // eg. Apple Inc.
@property (nonatomic, readonly, copy, nullable) NSString *thoroughfare; // street name, eg. Infinite Loop
@property (nonatomic, readonly, copy, nullable) NSString *subThoroughfare; // eg. 1
@property (nonatomic, readonly, copy, nullable) NSString *locality; // city, eg. Cupertino
@property (nonatomic, readonly, copy, nullable) NSString *subLocality; // neighborhood, common name, eg. Mission District
@property (nonatomic, readonly, copy, nullable) NSString *administrativeArea; // state, eg. CA
@property (nonatomic, readonly, copy, nullable) NSString *subAdministrativeArea; // county, eg. Santa Clara
@property (nonatomic, readonly, copy, nullable) NSString *postalCode; // zip code, eg. 95014
@property (nonatomic, readonly, copy, nullable) NSString *ISOcountryCode; // eg. US
@property (nonatomic, readonly, copy, nullable) NSString *country; // eg. United States
@property (nonatomic, readonly, copy, nullable) NSString *inlandWater; // eg. Lake Tahoe
