iOS后台定位并实时向服务器发送位置

第一步：开启后台模式，选中定位，选择project --> capabilities-->Backgorund Modes --> Location updates 如图：

开启后台模式

第二步：在info.list 文件中添加如下配置

允许 http 请求 ，ios 9 之后需要添加，便于向服务器发送请求
NSAppTransportSecurity  
    
  NSAllowsArbitraryLoads   
    
 

添加定位权限，ios8之后需要添加，否则无法定位
NSLocationWhenInUseUsageDescription
  YES  
NSLocationAlwaysUsageDescription
  YES
NSLocationAlwaysAndWhenInUseUsageDescription
  YES

第三步：代码如下

#import "ViewController.h"
#import 

@interface ViewController ()

@property (nonatomic, strong) CLLocationManager *locationManager;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.view.backgroundColor = [UIColor whiteColor];
    self.title = @"后台定位";
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;
    [self.locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
    if ([[UIDevice currentDevice].systemVersion floatValue] > 8)     {
        /** 请求用户权限：分为：只在前台开启定位  /在后台也可定位， */
        /** 只在前台开启定位 */
        //        [self.locationManager requestWhenInUseAuthorization];
        /** 后台也可以定位 */
        [self.locationManager requestAlwaysAuthorization];
    }
    if ([[UIDevice currentDevice].systemVersion floatValue] > 9)     {
        /** iOS9新特性：将允许出现这种场景：同一app中多个location manager：一些只能在前台定位，另一些可在后台定位（并可随时禁止其后台定位）。 */
        [self.locationManager setAllowsBackgroundLocationUpdates:YES];
    }
    /** 开始定位 */
    [self.locationManager startUpdatingLocation];
}

#pragma mark -  定位代理方法
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
    CLLocation *loc = [locations objectAtIndex:0];
    NSLog(@"经纬度  %f  %f ",loc.coordinate.latitude,loc.coordinate.longitude);
    NSURLSession *session = [NSURLSession sharedSession];
    NSURLSessionDataTask *task = [session dataTaskWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://ac.ybjk.com/ua.php"]] completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        NSLog(@"response  %@",response);
        NSString *result = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
        NSLog(@"result %@",result);
    }];
    [task resume];
}
@end
