Question

我是iphone的新手通过使用CLLocation我可以找到纬度和经度，但它不适用于在3.2.1中工作的iphonesimulater4.0，请任何人告诉我如何计算纬度和经度在iphone4.0的经度。提前致谢

Answer 1

CLLocationCoordinate2D location =
        [[[mapview userLocation] location] coordinate];

//NSLog(@"Location found from Map: %f %f",
        location.latitude,location.longitude);

Answer 2

此概念直接在您的应用中删除并检查它是否为纬度和长。

#pragma mark locationManager delegate 

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{    
    //if the time interval returned from core location is more than two minutes we ignore it because it might be from an old session
    if(abs([newLocation.timestamp timeIntervalSinceDate: [NSDate date]]) < 120) 
    {             
        //CLLocation *test = [[CLLocation alloc] initWithLatitude:-33.857034 longitude:151.035929];

        currentLocation = newLocation;
        coordinates = newLocation.coordinate;

        latitude = currentLocation.coordinate.latitude;
        longitude = currentLocation.coordinate.longitude;
        [locationManager stopUpdatingLocation];
    }
}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    NSLog(@"%@", [error description]);
}

Answer 3

位置仅显示在真实设备上。您可能会发现CLLocationManager中的值可以在模拟器中运行（可能来自您的交换机 - 虽然它不会非常准确）但地图上的蓝色引脚将始终位于CA中！

如何在iphone4.0中找到经纬度？
