Reading the GPS data from the image returned by the camera in iOS iphone

Question

I need to get the GPS coordinates of an image taken with the iOS device\'s camera. I do not care about the Camera Roll images, just the image taken with UIImagePickerControl

Answer 1

This is tested on iOS 8 and works for videos so it should work similarly for photos with a few tweaks.

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

    NSURL *videoUrl = (NSURL *)[info objectForKey:UIImagePickerControllerMediaURL];
    NSString *moviePath = [videoUrl path];

    if ( UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(moviePath) ) {

        ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];

        [assetLibrary assetForURL:[info objectForKey:UIImagePickerControllerReferenceURL] resultBlock:^(ALAsset *asset) {

            CLLocation *location = [asset valueForProperty:ALAssetPropertyLocation];
            NSLog(@"Location Meta: %@", location);

        } failureBlock:^(NSError *error) {
            NSLog(@"Video Date Error: %@", error);
        }];

    }

}
