iOS上的自定义键盘带有显示图像的按钮

Question

i具有以下代码成功在iPad上运行的代码。

func setupLockPinSection() {
        let keys = ["1", "2","3", "4","5", "6","7", "8","9", "0", "Clear", "Done"]
        let kbFrame = CGRect(x: 0, y: 0, width: view.frame.width, height: 400)
        if let customKeyboard = Bundle.main.loadNibNamed("MACustomKeyboard", owner: self, options: nil)?.first as? MACustomKeyboard {
            customKeyboard.frame = kbFrame
            customKeyboard.setKeyboardButtons(keys)
            lockPin1.inputView = customKeyboard
            //Number Tapped
            customKeyboard.numberTappedBlock = { [weak self] view, text in
                if let textFieldText = self?.lockPin1.text, let t = text {
                    self?.lockPin1.text = textFieldText + t
                }
            }
            //Done button Tapped
            customKeyboard.doneTappedBlock = { [weak self] view in
                self?.lockPin1.resignFirstResponder()
            }
            //Clear Button Tapped
            customKeyboard.clearTappedBlock = { [weak self] view in
                if let text = self?.lockPin1.text, text.characters.count > 0 {
                    self?.lockPin1.text = text.substring(to: text.index(text.endIndex, offsetBy: -1))
                }
            }
        }
        if let customKeyboard = Bundle.main.loadNibNamed("MACustomKeyboard", owner: self, options: nil)?.first as? MACustomKeyboard {
            customKeyboard.frame = kbFrame
            customKeyboard.setKeyboardButtons(keys)
            lockPin2.inputView = customKeyboard
            //Number Tapped
            customKeyboard.numberTappedBlock = { [weak self] view, text in
                if let textFieldText = self?.lockPin2.text, let t = text {
                    self?.lockPin2.text = textFieldText + t
                }
            }
            //Done button Tapped
            customKeyboard.doneTappedBlock = { [weak self] view in
                self?.lockPin2.resignFirstResponder()
            }
            //Clear Button Tapped
            customKeyboard.clearTappedBlock = { [weak self] view in
                if let text = self?.lockPin2.text, text.characters.count > 0 {
                    self?.lockPin2.text = text.substring(to: text.index(text.endIndex, offsetBy: -1))
                }
            }
        }
        lockPin1.text = UserDefaults.standard.string(forKey: "lockPin")
        lockPin2.text = UserDefaults.standard.string(forKey: "lockPin")
    }

我想用显示图像(隐藏键盘按钮，清除按钮(，像iOS默认键盘上的清除和完成按钮一样。我想这样做，因为，对于我的锁定PIN功能，我只想使用数字，而在iPad上，它不允许使用。因此，我需要制作自定义的键盘。

这是我现在使用上述代码

键盘向下按钮(右下角的按钮(和清除按钮(右上角的按钮(，我想在自定义键盘中实现它们，这样我就有它们，而不是我的"清除"one_answers"完成"按钮

这就是我想完成的！
