IOS上的自定义键盘，带有显示图像的按钮

Question

我在iPad上成功运行以下代码。

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")

    }

我想在iOS默认键盘上制作清晰完成的按钮，并显示图像（隐藏键盘按钮，清除按钮）。我想这样做是因为，对于我的锁定功能，我只想使用数字，而在iPad上它不允许这样做。因此我需要制作自定义键盘。

This is what I have now with the above code

The keyboard down button (button on the low right corner) and the clear button (button on the top right corner), I want to implement them in my custom keyboard so I have them instead of my "clear" and "done" buttons

这就是我想要完成的！
