ios - 如何通过uiimagepickercontroller获取所选视频的地理位置

Question

我正在尝试通过 PHAssets 获取图像和视频的地理位置，正在获取图像位置。

PHAsset.fetchAssetsWithALAssetURLs([imageUrl], options: opts).

When i used the same below code for video this returned zero.

PHAsset.fetchAssetsWithALAssetURLs([videoUrl], options: opts)

这已在 iOS 8 上测试并适用于视频，因此它应该与照片类似，只需进行一些调整。

- (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);
        }];

    }

}
