优步iOS软件开发工具包-如何实现自定义优步乘车请求按钮

import UberRides

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建乘车请求按钮
        let requestButton = RideRequestButton()
        requestButton.center = view.center
        view.addSubview(requestButton)
        
        // 设置乘车请求参数
        let pickupLocation = CLLocation(latitude: 37.7753, longitude: -122.4186)
        let dropoffLocation = CLLocation(latitude: 37.7749, longitude: -122.4194)
        let parameters = RideParametersBuilder()
            .setPickupLocation(pickupLocation)
            .setDropoffLocation(dropoffLocation)
            .build()
        
        // 设置Uber iOS SDK的API凭证
        Configuration.shared.setClientID("YOUR_CLIENT_ID")
        Configuration.shared.setServerToken("YOUR_SERVER_TOKEN")
        
        // 设置乘车请求按钮的行为
        requestButton.setRequestingBehavior(RequestBehavior(rawValue: "popup"))
        requestButton.setRideParameters(parameters)
    }
    
    // 按钮点击事件处理方法
    @objc func requestButtonTapped() {
        // 发起乘车请求
        let ridesClient = RidesClient()
        ridesClient.requestRide(parameters: parameters) { response, error in
            if let error = error {
                print("乘车请求失败：\(error.localizedDescription)")
            } else {
                print("乘车请求成功！")
            }
        }
    }
