Paytm SDK iOS快速集成

Question

我設置了代理PGTransactionDelegate，但是它顯示了一個錯誤，例如視圖控制器不符合協議“ PGTransactionDelegate ”

碼：

橋接頭中的Paytm目標頭

#import "PaymentsSDK.h

視圖控制器中的委托方法

// On Successful Payment
func didSucceedTransaction(controller: PGTransactionViewController, response: [NSObject : AnyObject]) {             
    print(response)
    print("Deducted amount :Rs. \(response["TXNAMOUNT"]!)")
    self.removeController(controller)
}

// On Failure
func didFailTransaction(controller: PGTransactionViewController, error: NSError, response: [NSObject : AnyObject]) {
    print(response)
    if response.count == 0 {
        print(response.description)
    }
    else if error != 0 {
       print(error.localizedDescription)
    }
    self.removeController(controller)
}

//On Cancellation
func didCancelTransaction(controller: PGTransactionViewController, error: NSError, response: [NSObject : AnyObject]) {
    print("Transaction has been Cancelled")
    self.removeController(controller)    
}

func didFinishCASTransaction(controller: PGTransactionViewController, response: [NSObject : AnyObject]) { 
    print(response);   
}

Answer 1

如果您最近將代碼更新為swift3.0，則委托函數的語法可能會有所更改，請檢查一下。

Answer 2

請在Bridging-Header中更正Paytm目標標頭

#import“ PaymentsSDK.h”

如果您使用的是swift 3或swift 4，那么這些方法可以解決您的問題

// On Successful Payment
func didSucceedTransaction(_ controller: PGTransactionViewController!, response: [AnyHashable : Any]!) {
    printLog(log: response)
}

// On Failure
func didFailTransaction(_ controller: PGTransactionViewController!, error: Error!, response: [AnyHashable : Any]!) {
    printLog(log: response)
    printLog(log: error.localizedDescription)
}

//On Cancellation
func didCancelTransaction(_ controller: PGTransactionViewController!, error: Error!, response: [AnyHashable : Any]!) {
    printLog(log: response)
    root.navigationController?.popViewController(animated: true)
}
