ios - 如何删除inputView swift下的灰色层

我正在尝试使Inputview的背景保持透明，但我只会将其变成灰色。



代码是:

    let fakeField : UITextField = UITextField(frame: CGRect.zero)
    //1
    InputViewCollection = InputView(frame: CGRect(x: 0, y: 0, width: 0, height: 216)) //Intialize custom input view
    InputViewCollection?.delegate = self //delegate
    InputViewCollection?.dataSource = self //datasource

    //2
    InputViewCollection?.backgroundColor = UIColor.clear
    self.fakeField.inputView = InputViewCollection //Assign input view
    self.fakeField.keyboardAppearance = .default
    self.view.addSubview(self.fakeField)

如何保持InputView的透明背景？

谢谢

最佳答案

使用inputView时，必须使用标准键盘的宽度。但是，您可以将一个空白视图设置为inputView，而将您的自定义键盘设置为inputAccessoryView。它没有灰色背景。解决方案是:

self.fakeField.inputView = UIView() // Set an empty, zero-sized view as inputView, in order to remove the standard keyboard
self.fakeField.inputAccessoryView = InputViewCollection // Set your custom keyboard this way instead
