Anyone encountered this error before when trying to access the photo library using the image picker?
任何人在尝试使用图像选择器访问照片库之前遇到此错误？
NSInvalidArgumentException Cannot set metadata in read-only store.
Any advise on what actually went wrong and suggestions on how I can resolve this will be greatly appreciated.
任何关于实际出错的建议以及如何解决这个问题的建议将不胜感激。

There's a post on the dev forums which might be slightly helpful (it's curiously marked "Apple Confidential Information" despite iOS 5 being released).
在开发论坛上有一篇帖子可能稍微有点帮助（尽管iOS 5被发布，它还是被奇怪地标记为“Apple机密信息”）。
We've been seeing these too. My first impression was that it was related to using PhotoStream while not being connected to iCloud, but "recordVersion:forStore:" suggests it's trying to upgrade the photo library to the 5.0 format (which it presumably can't do as an unprivileged/sandboxed/etc process).
我们也一直在看这些。我的第一印象是它与使用PhotoStream而没有连接到iCloud有关，但是“recordVersion：forStore：”表示它正在尝试将照片库升级到5.0格式（它可能不能作为非特权/沙盒来做） / etc process）。
In addition to "sync with iTunes", the following things might fix the problem:
除了“与iTunes同步”之外，以下内容可能会解决问题：
- Launching Photos
- 启动照片
- Launching Camera and taking a picture
- 启动相机并拍照
This doesn't seem to have been fixed in OS 5.0.1, but the number of reports has drastically reduced, suggesting people's photo libraries are eventually being upgraded.
这似乎没有在OS 5.0.1中修复，但报告的数量已大幅减少，这表明人们的照片库最终正在升级。

This issue is IOS5 only- have asked Apple on the dev forums, but no answer. I have not been able to repro myself, but..
这个问题只是IOS5-在开发论坛上问苹果，但没有答案。我无法自责，但..
My beta testers reported that syncing with iTunes seems to clear this error up- so my guess is that iTunes sync is fixing a permissions problem.
我的测试版测试人员报告说，与iTunes同步似乎可以清除此错误 - 所以我的猜测是iTunes同步正在解决权限问题。
I wrapped this code in a @try/@catch but it's still crashing :(.
我把这个代码包装在@ try / @ catch中，但它仍然崩溃:(。
- (void)showImagePicker {
UIImagePickerController *imagePicker = [[[UIImagePickerController alloc] init] autorelease];
imagePicker.delegate = self;
imagePicker.hidesBottomBarWhenPushed = YES;
imagePicker.allowsEditing = YES;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[tabController presentModalViewController:imagePicker animated:YES]; // sometimes crash
}
also getting the same crash infrequently/non-reproducibly for other users when I call UIImageWriteToSavedPhotosAlbum
当我打电话给UIImageWriteToSavedPhotosAlbum时，其他用户也很少/不可重复地发生同样的崩溃
