#import MapKit/MapKit.h两个头文件然后.m中的具体代码如下#import ANNViewController.hinterface ANNViewController ()
property (strong, nonatomic) IBOutlet UILabel *longitude;
property (strong, nonatomic) IBOutlet UILabel *latitude;property (strong, nonatomic) IBOutlet UILabel *location;
property (strong, nonatomic) CLLocationManager *locationManager;endimplementation ANNViewController- (void)viewDidLoad
{[super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.self.view.backgroundColor [UIColor whiteColor];//创建CLLocationManager对象self.locationManager [[CLLocationManager alloc] init];//设置代理为自己self.locationManager.delegate self;}
- (IBAction)locationButton:(UIButton *)sender {[self.locationManager startUpdatingLocation];
}- (void)locationManager:(CLLocationManager *)managerdidUpdateToLocation:(CLLocation *)newLocationfromLocation:(CLLocation *)oldLocation
{//将经度显示到label上self.longitude.text [NSString stringWithFormat:%lf, newLocation.coordinate.longitude];//将纬度现实到label上self.latitude.text [NSString stringWithFormat:%lf, newLocation.coordinate.latitude];// 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];//将获得的所有信息显示到label上self.location.text placemark.name;//获取城市NSString *city placemark.locality;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;}NSLog(city %, 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];
}主要就是直辖市的城市获得需要拐个弯iOS7添加了一个新的方法代替了上面这个方法- (void)locationManager:(CLLocationManager *)managerdidUpdateLocations:(NSArray *)locations
{NSLog(longitude %f, ((CLLocation *)[locations
lastObject]).coordinate.longitude);NSLog(latitude %f, ((CLLocation *)[locations lastObject]).coordinate.latitude);[manager stopUpdatingLocation];
}后面的处理和上面的方法一样大家可以看一下。另外还有一些CLGeocoder的属性如下property (nonatomic, readonly) NSDictionary *addressDictionary;// address dictionary properties
property (nonatomic, readonly) NSString *name; // eg. Apple Inc.
property (nonatomic, readonly) NSString *thoroughfare; // street address, eg. 1 Infinite Loop
property (nonatomic, readonly) NSString *subThoroughfare; // eg. 1
property (nonatomic, readonly) NSString *locality; // city, eg. Cupertino
property (nonatomic, readonly) NSString *subLocality; // neighborhood, common name, eg. Mission District
property (nonatomic, readonly) NSString *administrativeArea; // state, eg. CA
property (nonatomic, readonly) NSString *subAdministrativeArea; // county, eg. Santa Clara
property (nonatomic, readonly) NSString *postalCode; // zip code, eg. 95014
property (nonatomic, readonly) NSString *ISOcountryCode; // eg. US
property (nonatomic, readonly) NSString *country; // eg. United States
property (nonatomic, readonly) NSString *inlandWater; // eg. Lake Tahoe
property (nonatomic, readonly) NSString *ocean; // eg. Pacific Ocean
property (nonatomic, readonly) NSArray *areasOfInterest; // eg. Golden Gate Park完整的工程如下附件下载地址https://github.com/winann/TestLocation.git 转载于:https://blog.51cto.com/winann/1532528
