[tenxun123]

提bug前必看
请先回答下列三个问题，否则不允处理，谢谢配合。
1、我最新的Demo是否有这个bug？【如果Demo没问题，请升级新版】
答：没有

2、你用的是什么版本？升级到最新版后是否正常？
答：3.6.6，升级最新版本后也有问题

3、是否有改动过我库内部的代码？【如有，请说明改动点】
答：没有

bug内容描述
第一次安装使用时选择允许访问相册权限后一片空白，第二次再次进入就好了

我如何复现这个bug？
首次安装后，第一次进入相册就会出现空白。复现概率比较低，但是确实存在

截图

其它说明
有没有其它要补充的？比如你的初始化TZImagePickerController的代码

[banchichen]

我的demo没问题，你的项目里低概率复现吗？

[tomsemi]

我这里在demo第一次使用，选择允许访问相册权限后，直接卡死 ,beta版本的iOS15.2系统:iOS15.2(19C5044b)

[banchichen]

@tomsemi 非beta系统会这样吗？卡死时有什么日志？

非beta系统测试下来不会卡死，日志：

@tomsemi 大概率是beta系统的bug，产时间卡住主线程，进程被看门狗杀了，可以保持观察下，发布正式版的时候应该好了

[jtouzy]

FYI, we had the same issue in our app on iOS 15.2.
It seems related that we call PHPhotoLibrary.shared().register(self) before asking for photo permission.
If we do it later, no more Apple failure.

@jtouzy Thanks, you're right. Thank you for your information!

- [[PHPhotoLibrary sharedPhotoLibrary] registerChangeObserver:self];

+ if ([[TZImageManager manager] authorizationStatusAuthorized]) {
+     [[PHPhotoLibrary sharedPhotoLibrary] registerChangeObserver:self];
+ }

The new version(3.6.8) has fixed this problem
