Question

我正在创建一个应用程序，允许用户拍照或从照片卷中选择一个，并通过电子邮件发送到特定地址。但是，以下代码有效，如果有人拍照，然后在发送电子邮件之前移动，则GPS位置不准确。

我有办法吗？

拍照，存放Lat＆amp;照片被带到变量的地方很长
从照片卷轴中选择一张照片，提取lat＆amp; long，并存储到变量

这是我的代码：

- (IBAction)takePhoto
{
    picker1 = [[UIImagePickerController alloc] init];
    picker1.delegate = self;
    [picker1 setSourceType: UIImagePickerControllerSourceTypeCamera];
    [self presentViewController:picker1 animated:YES completion:NULL];
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    [locationManager startUpdatingLocation];


}

- (IBAction)chooseExisting
{
    picker2 = [[UIImagePickerController alloc] init];
    picker2.delegate = self;
    [picker2 setSourceType: UIImagePickerControllerSourceTypePhotoLibrary];
    [self presentViewController:picker2 animated:YES completion:NULL];
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    [locationManager startUpdatingLocation];



}


#pragma mark - CLLocationManagerDelegate

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    NSLog(@"didFailWithError: %@", error);
    UIAlertView *errorAlert = [[UIAlertView alloc]
                               initWithTitle:@"Error" message:@"Failed to Get Your Location" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [errorAlert show];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    NSLog(@"didUpdateToLocation: %@", newLocation);
    CLLocation *currentLocation = newLocation;

    if (currentLocation != nil) {
        longditute = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude];
        Latitude = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];
    }
    // Stop Location Manager
    [locationManager stopUpdatingLocation];
}



- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

   image = [info objectForKey:UIImagePickerControllerOriginalImage];
   [imageView setImage:image];
   [self dismissViewControllerAnimated:YES completion:NULL];
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
    [self dismissViewControllerAnimated:YES completion:NULL];
}

捕获照片的GPS位置和存储的图像
