sdk8.0以后，GPS定位的问题

来源：互联网发布：linux bind 配置编辑：程序博客网时间：2024/05/20 20:57

1. 在 info.plist里加入对应的缺省字段，值设置为YES（前台定位写上边字段，前后台定位写下边字段）
NSLocationWhenInUseUsageDescription //允许在前台获取GPS的描述

NSLocationAlwaysUsageDescription //允许在前、后台获取GPS的描述

2. 调用请求：

//设置定位权限仅ios8有意义
[locationManager requestWhenInUseAuthorization];// 前台定位

[locationManager requestAlwaysAuthorization];// 前后台同时定位

3. 添加坐标点：Product->Scheme->EditScheme

Options->Default Location->(选择一个地点)

4.添加Framework

MapKit.framework

CoreLocation.framework

代码片段

-(IBAction)StartGPS:(id)sender{    if (self.locationManager == nil) {        self.locationManager = [[CLLocationManager alloc] init];//        [self.locationManager requestAlwaysAuthorization];//前台和后台都要进行定位        [self.locationManager requestWhenInUseAuthorization];//只有在前台的时候才进行定位    }    self.locationManager.delegate = self;    [self.locationManager startUpdatingLocation];}- (IBAction)StopGPS:(id)sender{    [self.locationManager stopUpdatingLocation];}#pragma mark - CLLocationDelegate- (void)locationManager:(CLLocationManager *)manager     didUpdateLocations:(NSArray *)locations{    CLLocation *location = [locations objectAtIndex:0];    [self.mapView setCenterCoordinate:location.coordinate animated:YES];    //定义显示的范围    MKCoordinateSpan theSpan;        theSpan.latitudeDelta=0.1;        theSpan.longitudeDelta=0.1;        //定义一个区域（用定义的经纬度和范围来定义）        MKCoordinateRegion theRegion;        theRegion.center=location.coordinate;        theRegion.span=theSpan;    [self.mapView setRegion:theRegion animated:YES];}
