1、首先加入工程的静态库
Build Phases -> Link Binary With Libraries -> +
\
2、在需要的VC中头文件、添加代理
3、在.m中声明属性
4、初始化CLLocationManager
5、CLLocationManagerDelegate - 方法
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(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;
//self.location.text = placemark.country;//中国
//self.location.text = placemark.administrativeArea;//山西省
//self.location.text = placemark.locality;//太原市
//self.location.text = placemark.subLocality;//万柏林区
//self.location.text = [NSString stringWithFormat:@"%@%@%@",placemark.administrativeArea,placemark.location,placemark.subLocality];
NSString *administrativeAreaStr = placemark.administrativeArea;
NSString *localityStr = placemark.locality;
NSString *subLocalityStr = placemark.subLocality;
self.location.text = [NSString stringWithFormat:@"%@ %@ %@",administrativeAreaStr,localityStr,subLocalityStr];
NSLog(@"信息1：%@",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);
_cityLable.text = city;
//[_cityButton setTitle:city forState:UIControlStateNormal];
}
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];
}
6、在Info.plist文件中加入
NSLocationAlwaysUsageDescription 和NSLocationWhenInUseUsageDescription 设置为String Valu是提示信息可以为空。
