你好, 按照上边的方式实现了, 我们采用albumShowMode方式为popup,有点小问题, 比如自定义相册为'xxx', 弹出后点击上边的标题展示albumList会发现显示的是'xxx',但是列表选中的却是'最近项目', 切换几次后'最近项目'又不见被替换为'xxx'了,这时列表里有2个'xxx'相册, 虽然可以修改自定义相册collection.isSelected = true稳定这种情况, 但是我们希望弹出相册列表时默认选中的是'xxx',同时'最近项目'也存在,这样可以实现吗?

        _ config: PickerConfiguration,
        options: PHFetchOptions
    ) -> PhotoAssetCollection? {
        if config.creationDate {
            options.sortDescriptors = [
                NSSortDescriptor(
                    key: "creationDate",
                    ascending: config.creationDate
                )
            ]
        }
        var collection: PhotoAssetCollection?
        fetchAssetCollections(options: options) { assetCollection, isCameraRoll, stop in
            if !isCameraRoll, assetCollection.albumName == "xxx" {
                collection = assetCollection
                stop.pointee = true
            }
        }
        if let collection {
//            collection.isSelected = true
            return collection
        }
        return DefaultPhotoFetchAssetCollection.fetchCameraAssetCollection(config, options: options)
    }```

我发现可以自定义PhotoFetchData,但是在重写fetchAssetCollections时遇到了一些问题,

这两个属性没有public,重写的时候无法使用.
我发现'最近项目'是下边这句代码替换掉的

所以我想重写这个方法,不知道重写这个方法是否可行,感觉重写后的select状态依然有些混乱.

这个问题下个版本会修改，不会替换掉第一个相册

from hxphotopicker.

试了最新的修改代码后相册已经不会被替换掉了, 然而发现有一个bug:

https://github.com/SilenceLove/HXPhotoPicker/assets/12481783/927e7131-99b0-4a49-bbb0-dc5862c44434
视频中可以看到打开自定义相册后选中状态有些错乱, 我调试了下大概知道原因:

self.cameraAssetCollection可能还没拿到的时候已经走到这个if判断里, 看起来2个queue执行完毕的先后顺序并不能确定,所以时好时坏.

最新的代码试试
