我在对应用程序进行调试时没有遇到这个问题。但是，当我们从TestFlight下载应用程序进行测试时，就会出现这个问题。问题是；在我们的登录页面中，填写用户名和密码文本字段后，按下登录按钮。只有在IOS14中，应用程序才会崩溃。
注意：当键盘处于活动状态时，应用程序屏幕顶部会显示密码文本字段。之后，当用户按下登录按钮时，首先关闭键盘辞职FirstResponder代码工作，然后下一个代码在(Dispatch Async Main After(0.2秒后工作，以防止外观不好。
self.resignTextField(item: self.view)
self.loginButton.isUserInteractionEnabled = false
DispatchQueue.main.asyncAfter(deadline: .now() + 0.2) { [weak self] in
self?.loginButton.isUserInteractionEnabled = true
self?.viewModel.login(username: username, password: password)
}
有人面临这个问题吗？这个问题发生在我们所有安装了ios 14的测试设备中。。

我发现了问题。安全文本模式下的旧Material.io TextField仅在iOS 14中会导致内存问题。所以我更新了它，修复了问题。
