在Mapview Xcode中更新位置 [英] Update Location in Mapview Xcode

问题描述

在我当前的项目中.

每一次50 meter用户移动都需要用户的位置.

I need user's location at every 50 meter user move.

因此，基本上，打开应用程序后，每个50 meter更改都需要用户位置，以便在Objective c中调用Web服务.我也希望在应用程序处于后台状态时运行相同的进程.

So Basically After open application every 50 meter change I need user location for call web service in Objective c. Also i want same process run when application is in background state.

预先感谢

推荐答案

在

//create location manager object
locationManager = [[CLLocationManager alloc] init];

//there will be a warning from this line of code
[locationManager setDelegate:self];

//and we want it to be as accurate as possible
//regardless of how much time/power it takes
[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];

//set the amount of metres travelled before location update is made
[locationManager setDistanceFilter:50];

并添加

if ([CLLocationManager locationServicesEnabled]) {
    [self.locationManager startUpdatingLocation];
}

更新

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
CLLocation *location = locations.lastObject;
NSLog(@"%@", location.description);

 //In here you get all details like

   NSLog(@"latitude = %@",location.coordinate.latitude);
   NSLog(@"longitude = %@",location.coordinate.longitude);
   NSLog(@"altitude = %@",location.altitude);
   NSLog(@"horizontalAccuracy = %@",location.horizontalAccuracy);
   NSLog(@"verticalAccuracy = %@",location.verticalAccuracy);
   NSLog(@"timestamp = %@",location.timestamp);
   NSLog(@"speed = %@",location.speed);
   NSLog(@"course = %@",location.course);

}
