仅在 UIKitCore [UIViewController viewDidMoveToWindow:shouldAppearOrDisappear:] iOS 12 中崩溃
Crash in UIKitCore [UIViewController viewDidMoveToWindow:shouldAppearOrDisappear:] iOS 12 only
我收到了相当数量的崩溃报告给 Crashlytics。这只发生在 iOS 12 上，我不知道如何重现。也许用户在 WKWebView 上并试图根据 31 SafariServices 0x21d216740 __107+[_SFAutomaticPasswordInputViewController inputViewControllerWithAutoFillContext:passwordRules:completion:]_block_invoke.29 + 104
中的提示输入密码
如果有谁有类似的崩溃或者想法，不胜感激

Fixed a crash related to password auto-fill screen
我遇到过类似的崩溃。只有当我按以下顺序有 3 UITextFields 时才会发生：电子邮件、密码、密码。对于密码字段 属性 isSecureTextEntry 设置为 true。为了使其崩溃，我将焦点更改为密码字段之一，切换到主屏幕并返回到应用程序。有时在主屏幕和应用程序之间的第二次或第三次切换时发生。
所以，就我而言，原因是 Firebase/Performance pod。我已经删除它一段时间了——这修复了错误。
更新：Firebase 团队在 5.19.0 中修复了这个错误。只需更新您的 firebase pods.
