I'm using it as a Viewcontroller class

Code:

Import

#import "CardIO.h"

#import "CardIOPaymentViewControllerDelegate.h"

-(void) Viewwillappear: (BOOL) Animated {

[Super viewwillappear:animated];

[Cardioutilities preload];

}

Start scanning

-(Ibaction) Scancard: (ID) sender

{

Cardiopaymentviewcontroller *scanviewcontroller = [[Cardiopaymentviewcontroller alloc] Initwithpaymentdelegate:self ];

[Self Presentviewcontroller:scanviewcontroller animated:yes completion:nil];

}

Here is the Proxy method

Cancel Scan

-(void) Userdidcancelpaymentviewcontroller: (Cardiopaymentviewcontroller *) Scanviewcontroller

{

NSLog (@ "User canceled payment info");

Handle User Cancellation here ...

[Scanviewcontroller Dismissviewcontrolleranimated:yes Completion:nil];

}

Scan complete

-(void) Userdidprovidecreditcardinfo: (cardiocreditcardinfo *) Info inpaymentviewcontroller: ( Cardiopaymentviewcontroller *) Scanviewcontroller

{

//Scan results

NSLog (@ "Received card info. Number:%@, expiry:%02i/%i, CVV:%@. ", Info.redactedcardnumber, Info.expirymonth, Info.expiryyear, INFO.CVV);

Use the card info ...

[Scanviewcontroller Dismissviewcontrolleranimated:yes Completion:nil];

}
