@property (nonatomic ,retain )CLLocationManager *locationManager;
4.開始定位
- (void)locate
//推断定位操作是否被同意
if ([CLLocationManagerlocationServicesEnabled ]) {
self.locationManager = [[CLLocationManager alloc] init] ;
self .locationManager .delegate =self ;
}else {
//提示用户无法进行定位操作
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:
@”提示”message :@”定位不成功,请确认开启定位”delegate:nilcancelButtonTitle :@”取消”otherButtonTitles :@”确定”,nil ];
[alertView show];
// 開始定位
[self .locationManagerstartUpdatingLocation ];
5.实现定位协议回调方法
pragma mark – CoreLocation Delegate
-(void)locationManager:(CLLocationManager )manager didUpdateLocations:(NSArray )locations
//此处locations存储了持续更新的位置坐标值，取最后一个值为最新位置，假设不想让其持续更新位置，则在此方法中获取到一个值之后让locationManager stopUpdatingLocation
CLLocation *currentLocation = [locations lastObject];
//获取当前所在的城市名
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
//依据经纬度反向地理编译出地址信息
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray array, NSError error)
if (array.count > 0)
CLPlacemark *placemark = [array objectAtIndex:0];
//将获得的全部信息显示到label 上
NSLog(@”%@”,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，仅仅能通过获取省份的方法来获得（假设city为空，则可知为直辖市）
city = placemark.administrativeArea;
self.cityName = 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。由于我们仅仅须要获得一次经纬度就可以，所以获取之后就停止更新
[managerstopUpdatingLocation ];
- (void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error {
if (error.code == kCLErrorDenied) {
// 提示用户出错原因。可按住Option 键点击 KCLErrorDenied 的查看很多其它出错信息，可打印error.code 值查找原因所在
