Paytm SDK iOS快速集成

Question

I set the delegate PGTransactionDelegate but it's showing an error like view-controller does not conform with protocol " PGTransactionDelegate "

code:

Paytm target header in Bridging-Header

#import "PaymentsSDK.h

Delegate method in view-controller

// 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

如果您最近将代码更新为swift3.0，则委托函数的语法可能会有所更改，请检查一下。

Answer 2

Please correct Paytm target header in Bridging-Header

#import "PaymentsSDK.h"

If you are using swift 3 or swift 4 then these method can resolve your problem

// 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)
}
