我试图让我的 Inputview 的背景透明,但我只把它变成灰色。
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)
如何保留 inputview 的透明背景?
谢谢
