iPhone中GPS定位如何使用

关键词

1.info.plist配置授权描述

2.引入库

3.CLLocationManager的使用

info.plist配置

在info.plist中根据情况加入以下两个string类型配置项，并填写描述

1.NSLocationAlwaysUsageDescription

2.NSLocationWhenInUseUsageDescription

引入库

-引入CoreLocation.framework

-在原文件中引入 <CoreLocation/CoreLocation.h>

代码实现

// 初始化

2.- (void)setupLocationManager {

3.    _locationManager = [[CLLocationManager alloc] init];

4.    _locationManager.desiredAccuracy = kCLLocationAccuracyBest;

5.    _locationManager.distanceFilter = kCLDistanceFilterNone;

6.
7.    if ([_locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {

8.        [_locationManager requestWhenInUseAuthorization];

9.    }

10.}

11.
12.// 调用此方法开始定位

13.- (void) startUpdatingLocation {

14.    if ([CLLocationManager locationServicesEnabled]) {

15.        _shouldHandleLocation = YES;

16.        _locationManager.delegate = self;

17.        [_locationManager startUpdatingLocation];

18.    } else {

19.        [SVProgressHUD showErrorWithStatus:@"请开启定位功能!"];

20.    }

21.}

23.#pragma mark - CLLocationManagerDelegate

24.- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations

25.{

26.    CLLocation *newLocation = [locations lastObject];

27.    if (_shouldHandleLocation) {

28.        _shouldHandleLocation = NO;

29.        _latitude = newLocation.coordinate.latitude;

30.        _longitude = newLocation.coordinate.longitude;
