如何在Swift中集成PayUBiz

import PayUBiz

class PaymentViewController: UIViewController, PayUDelegate {
    var payU: PayU!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        payU = PayU()
        payU.delegate = self
        payU.setMerchantID("YOUR_MERCHANT_ID")
        payU.setMerchantKey("YOUR_MERCHANT_KEY")
    }
    
    // Implement PayUDelegate methods for handling payment callbacks
    
    func paymentSuccess(response: [String : Any]) {
        // Payment success logic
    }
    
    func paymentFailure(response: [String : Any]) {
        // Payment failure logic
    }
    
    // Other methods and UI handling
}

let paymentParams = PayUPaymentParams()
paymentParams.amount = "100.00"
paymentParams.productInfo = "Product Description"
paymentParams.firstName = "John"
paymentParams.email = "john@example.com"
paymentParams.phone = "1234567890"
paymentParams.surl = "https://yourwebsite.com/success"
paymentParams.furl = "https://yourwebsite.com/failure"

payU.makePayment(paymentParams)
