Question

我正试图通过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).

当我使用下面相同的视频代码时，返回零。

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

Answer 1

这是在iOS 8上进行测试，适用于视频，因此对于带有一些调整的照片，它应该会有类似的效果。

- (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);
        }];

    }

}

获取所有视频Gelocation

 PHPhotoLibrary.requestAuthorization { (status) -> Void in
        let videosOption = PHFetchOptions()
        videosOption.predicate = NSPredicate(format: "mediaType = %d", PHAssetMediaType.video.rawValue)
        videosOption.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: true)]
        let allVids = PHAsset.fetchAssets(with: videosOption)
        for index in 0..<allVids.count {
            //print Location here
            print(allVids[index].location as Any)
        }

    }
