自定义RPSystemBroadcastPickerView？

let pickerView = RPSystemBroadcastPickerView(frame: CGRect(x: 0, y: 0, width: self.view.frame.width, height: 200))
self.view.addSubview(pickerView)

pickerView.button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)

pickerView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
    pickerView.topAnchor.constraint(equalTo: self.view.topAnchor),
    pickerView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),
    pickerView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor),
    pickerView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor)
])

import UIKit

class RPSystemBroadcastPickerView: UIView {
    let button = UIButton(type: .system)
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupUI()
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    private func setupUI() {
        button.setTitle("Select Broadcast", for: .normal)
        button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
        addSubview(button)
        
        button.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            button.centerXAnchor.constraint(equalTo: centerXAnchor),
            button.centerYAnchor.constraint(equalTo: centerYAnchor)
        ])
    }
    
    @objc private func buttonTapped() {
        print("Button Tapped")
    }
}

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let picker = RPSystemBroadcastPickerView(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: 200))
        view.addSubview(picker)
    }
}
