我有一个EditProfileViewController，带有一个tableview和textfield。在其中一个文本字段中，我有一个pickerView作为inputView，在inputAccessoryView中有一个toolBar。当视图加载时，我选择firstName文本字段，并返回并移动到lastName文本字段时，我得到一个约束警告。

[LayoutConstraints] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want. 
Try this: 
    (1) look at each constraint and try to figure out which you don't expect; 
    (2) find the code that added the unwanted constraint or constraints and fix it. 
(
"<NSLayoutConstraint:0x2809a4640 'assistantHeight' TUISystemInputAssistantView:0x1113b11a0.height == 45   (active)>",
"<NSLayoutConstraint:0x2809a0320 'assistantView.bottom' TUISystemInputAssistantView:0x1113b11a0.bottom == _UIKBCompatInputView:0x11a437e80.top   (active)>",
"<NSLayoutConstraint:0x2809a05a0 'assistantView.top' V:|-(0)-[TUISystemInputAssistantView:0x1113b11a0]   (active, names: '|':UIInputSetHostView:0x11d06ce50 )>",
"<NSLayoutConstraint:0x280943840 'inputView.top' V:|-(0)-[_UIKBCompatInputView:0x11a437e80]   (active, names: '|':UIInputSetHostView:0x11d06ce50 )>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x2809a0320 'assistantView.bottom' TUISystemInputAssistantView:0x1113b11a0.bottom == _UIKBCompatInputView:0x11a437e80.top   (active)>

当我在两个默认文本字段之间切换时，会发生这种情况，我不明白为什么。我做了一些研究，从我可以看到这是iOS 13的一个bug，因为在iOS 10的另一个设备上，这种情况并没有发生。
消除此约束问题的解决方法是设置autoCorrectionType = false。但我想启用它。我想这是因为我在countryTextfield的inputView中有一个pickerView，但我不知道如何解决这个问题。
