使用`inputAccessoryView`

Question

我添加了一个自定义inputAccessoryView，其中包含一个子类UITextView。

当我点击inputAccessoryView时，键盘将其向上推，并显示以下2条警告：

  

API错误：<_UIKBCompatInputView：0x7f92815391b0;框架=（0 0; 0 0）;层=>返回0宽度，假设UIViewNoIntrinsicMetric

     

API错误：<_UIKBCompatInputView：0x7f92815391b0;框架=（0 0; 0 0）;层=>返回0宽度，假设UIViewNoIntrinsicMetric

当我在视图控制器上移动空的collectionView时，键盘会随着inputAccessoryView移回到屏幕底部而下降，然后显示另外2条警告：

  

[View]第一响应者警告：“ TextInputView：0x7f9282847000; baseClass = UITextView;框架=（10 10; 354 27）;文字=''; clipsToBounds = YES; poseRecognizers =;层=; contentOffset：{0，3}; contentSize：{158.5，30.5}; AdjustedContentInset：{0，0，14，0}>'在从层次结构中删除时拒绝resignFirstResponder

     

-[UIWindow endDisablingInterfaceAutorotationAnimated：]在不匹配-beginDisablingInterfaceAutorotation的情况下调用。忽略。

是什么原因导致这些警告，以及如何防止它们出现？我在这里查找了类似的问题，但没有一个明确的答案。

根据要求，inputAccessoryView：

class BigInputBar: UIView, UITextViewDelegate {
     
     // MARK: - Subviews
     let separatorLine = SeparatorLine()
     
     // View that contains everything
     var backgroundView: UIView = {
          let view = UIView()
          view.translatesAutoresizingMaskIntoConstraints = false
          return view
     }()
     
     lazy var inputTextView: TextInputView = {
          let textView = TextInputView()
          textView.translatesAutoresizingMaskIntoConstraints = false
          textView.backgroundColor = .clear
          
          return textView
     }()
     
     var sendButton: UIButton = {
          let button = UIButton(frame: .zero)
          let image = UIImage.getImage(named: "chevron-right")
          button.setImage(image, for: [])
          button.addTarget(self, action: #selector(sendButtonTapped), for: .touchUpInside)
          button.translatesAutoresizingMaskIntoConstraints = false
          button.setBackgroundImage(image, for: .highlighted) //Fun develop only graphic
          button.backgroundColor = .clear
          button.isEnabled = false
          return button
     }()
     
     @objc private func sendButtonTapped(){
          print("Button Tapped")
     }
     
     // MARK: Properties
     override var intrinsicContentSize: CGSize {
          return CGSize(width: bounds.width, height: 60)
     }
     
     // MARK: - Init Methods
     convenience init() {
          self.init(frame: .zero)
     }
     
     override init(frame: CGRect) {
          super.init(frame: frame)
          setup()
     }
     
     required public init?(coder aDecoder: NSCoder) {
          super.init(coder: aDecoder)
          setup()
     }
     
     func setup() {
          autoresizingMask = [.flexibleHeight]
          
          addSubview(backgroundView)
          addSubview(separatorLine)
          
          backgroundView.addSubview(sendButton)
          backgroundView.addSubview(inputTextView)
          
          setupConstraints()
          
          inputTextView.delegate = self
     }
     
     private func setupConstraints() {
          
          separatorLine.leftAnchor.constraint(equalTo: self.leftAnchor, constant: 0).isActive = true
          separatorLine.rightAnchor.constraint(equalTo: self.rightAnchor, constant: 0).isActive = true
          separatorLine.topAnchor.constraint(equalTo: self.topAnchor, constant: 0).isActive = true
          
          backgroundView.leftAnchor.constraint(equalTo: self.leftAnchor, constant: 0).isActive = true

          backgroundView.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: 0).isActive = true
          backgroundView.topAnchor.constraint(equalTo: separatorLine.bottomAnchor, constant: 0).isActive = true
          
          sendButton.rightAnchor.constraint(equalTo: backgroundView.rightAnchor, constant: -10).isActive = true
          sendButton.topAnchor.constraint(equalTo: backgroundView.topAnchor,constant: 10).isActive = true
          sendButton.widthAnchor.constraint(equalToConstant: 30).isActive = true
          sendButton.heightAnchor.constraint(equalToConstant: 30).isActive = true
          
          let leftTextView = inputTextView.leftAnchor.constraint(equalTo: backgroundView.leftAnchor, constant: 10)
          let rightTextView = inputTextView.rightAnchor.constraint(equalTo: sendButton.leftAnchor, constant: -10)
          let bottomTextView = inputTextView.bottomAnchor.constraint(equalTo: backgroundView.bottomAnchor, constant: -20)
          let topTextView = inputTextView.topAnchor.constraint(equalTo: backgroundView.topAnchor,constant: 10)
          
          NSLayoutConstraint.activate([leftTextView, rightTextView, bottomTextView, topTextView])
     }
