获取设备当前的海拔高度和垂直高度

来源：筏尚旅游网

首先导入

#import <CoreLocation/CoreLocation.h>

#import <MapKit/MapKit.h>

添加请求权限的key

    <key>NSLocationWhenInUseUsageDescription</key>
    <string>YES</string>
    <key>NSLocationAlwaysUsageDescription</key>
    <string>YES</string>

然后就可以创建 locationManager 对象

    CLLocationManager *locationManager = [[CLLocationManager alloc] init];
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    locationManager.delegate = self;
    [locationManager requestAlwaysAuthorization];
    [locationManager startUpdatingLocation];

实现代理方法

-(void)locationManager:(CLLocationManager *)manager
   didUpdateToLocation:(CLLocation *)newLocation
          fromLocation:(CLLocation *)oldLocation
{
    float altitude = newLocation.altitude;
    NSLog(@"海拔高度为：%.2fm",altitude);
    NSLog(@"垂直精度为：%.2fm",newLocation.verticalAccuracy);
}




出现错误


- (void)locationManager:(CLLocationManager *)manager
       didFailWithError:(NSError *)error{
    NSLog(@"%@",error);
}
