Here’s why deleted iPhone photos returned to some iOS devices
这就是删除的iPhone 照片返回到某些 iOS 设备的原因

We finally have a better understanding of why devices running iOS 17.5 started resurfacing long-deleted photos, courtesy of Apple and some third-party researchers. While Apple released the iOS 17.5.1 iPhone update to fix the issue earlier this week, attributing it to a “database corruption,” the company remained tight-lipped about what was specifically causing old files — including deleted nudes, in some reports — to start appearing on devices that never hosted them.
感谢 Apple 和一些第三方研究人员的帮助，我们终于更好地理解了为什么运行 iOS 17.5 的设备开始重新显示长期删除的照片。 尽管苹果公司本周早些时候发布了 iOS 17.5.1 iPhone 更新来解决该问题，并将其归因于“数据库损坏”，但该公司仍然对具体导致旧文件（在一些报告中包括删除的裸照）的原因守口如瓶。 开始出现在从未托管过它们的设备上。

Elaborating on the issue to 9to5Mac, Apple says it was caused by a corrupt database entry on the device’s file system, impacting files on the devices themselves and not those that had been synced to iCloud. Those files may have been carried over from older devices when restored from a backup or during device-to-device transfer.
Apple 在向 9to5Mac 详细说明该问题时表示，这是由设备文件系统上的数据库条目损坏造成的，影响的是设备本身的文件，而不是那些已同步到 iCloud 的文件。 当从备份恢复或在设备到设备传输期间，这些文件可能是从旧设备继承的。

“Based on this code, we can say that the photos that reappeared were still lying around on the filesystems and that they were just found by the migration routine added in iOS 17.5,” said Synacktiv. “Based only on this analysis, it is not possible to conclude how the photos remained on the filesystem in the first place.” The Synacktiv article then directs readers to this comment on Reddit for a plausible explanation, which includes the possibility of users saving images to both the File app and Photos app and only deleting the latter.
Synacktiv 表示：“根据这段代码，我们可以说重新出现的照片仍然存在于文件系统中，并且它们只是被 iOS 17.5 中添加的迁移例程发现的。” “仅根据此分析，无法断定照片最初是如何保留在文件系统上的。” Synacktiv 文章随后引导读者查看 Reddit 上的这条评论，寻求合理的解释，其中包括用户可以将图像同时保存到“文件”应用和“照片”应用中，而只删除后者。
