UITextField becomeFirstResponder随机崩溃iOS应用程序

我开发了一个应用程序，该应用程序具有多个带文本字段辉光边框的文本字段。当我进行内部测试时，它一直工作正常，但我看到Fabric使用以下堆栈跟踪报告崩溃。我错过了什么来追踪这个问题？任何人都可以在这个问题上提出一些看法吗？UITextField becomeFirstResponder随机崩溃iOS应用程序

您可以在视图控制器中使用TapGesture事件来退出键盘吗？ –

是的，我正在使用TapGesture已经退出键盘 –

我多次面临同样的错误。 –

我得到了相同的崩溃before.And的原因是视图控制器已经发布和UITextField.delegate没有设置为零，是一个悬摆指针的问题。我在视图控制器的dealloc方法中设置了UITextField.delegate = nil，修正了bug。

感谢您的更新。我在dealloc中保持零。但我无法确认它是否得到修正。因为这次崩溃并没有通过我的内部测试来确认此修复是否能够实现无崩溃。你能给出一些光线来制作它并确认修复吗？ –

@SrinivasG您是否可以确认将代表设置为零可解决问题？如果没有，你有没有想出正确的解决方案？ – Carl

@SrinivasG你能否确认它是否解决了你的问题？ –
