4 years ago 什么分类多次调用，能详细点吗

4 years ago @caoyunxiao var images = await PhotoAlbumManager.getDescAlbumImg(); var videos = await PhotoAlbumManager.getDescAlbumVideo();
结果不对
120011676
commented
4 years ago 1.窗口确认权限后，不能及时获取到图片 2.图片多些，方法慢，建议有什么异步可选择下

4 years ago var images = await PhotoAlbumManager.getDescAlbumImg(); var videos = await PhotoAlbumManager.getDescAlbumVideo(); 我测试了，不存在结果不对的情况吧，图片是图片，视频是视频，你那边会乱？ 有点慢是因为 HEIC格式的转码，否则flutter无法显示

4 years ago 可以考虑提前获取相册资源，用的时候直接取就行

4 years ago @caoyunxiao 切换到photo_manager了，快，丰富api

}首先你这个使用全部相册资源，需要考虑预加载，否则速度起不来。少数资源不存在这种问题，建议在使用之前先执行PhotoAlbumManager.getDescAlbum()，它内部有缓存机制，在你真正需要用的时候，再重新执行，速度应该能达到你的预期 还有就是originalPath 字段，不一定有值的，由于苹果机制，原始资源可能在iCloud，需要下载，内部已经提供了相关的api，建议断点调试看看。
ios 11.1.2 下分类查询不正确，图片都跑到视频里面了 ios 13.4.1 查询不到图片和视频
