位置管理器在1小时后停止更新

Question

根据我的应用程序要求，我们会进行跟踪，并且工作正常。但是当我启用GPS服务并且从未移动并将iPhone放在桌面上1小时之后我出现了30分钟的旅程但是我的更新位置代表从未打过电话时出现了问题。下面是我的代码：

locationManager = [[CLLocationManager alloc]init]; 
locationManager.delegate = self;     
locationManager.distanceFilter = 150.0f; 
locationManager.desiredAccuracy = kCLLocationAccuracyBest; 

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0")) { 
    setPausesLocationUpdatesAutomatically:NO]; 
}

Answer 1

编写此代码：

[locationManager startUpdatingLocation];

＆安培;也写下他们的代表方法：

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
   NSMutableString *latString = [NSMutableString stringWithFormat:@"%f",newLocation.coordinate.latitude];

   NSMutableString *lngString = [NSMutableString stringWithFormat:@"%f",newLocation.coordinate.longitude];
}
