Pay U Payment Gateway
Sometimes we require to integrate an application with Payu payment gateway . for this, we require to follow some steps.
1: There are two ways to integrate with Payu .( seamless and non-seamless(inbuilt UI part)).
2: Here I am defining about non-seamless Integration.
3: Go to that Url and download their SDK. https://github.com/payu-intrepos/Documentations/wiki/8.-iOS-SDK-integration
4: Drag Payu folder in your Xcode project.
5: do some changes in the project.
- Add
libz.tbdlibraries to your project (Project->Build Phases->Link Binary With Libraries) - Add
-ObjCin Other Linker Flags in Project Build Settings(Project->Build Settings->Other Linker Flags) - To run the app on iOS9, please add the below code in info.plist
12345<key>NSAppTransportSecurity</key><dict><key>NSAllowsArbitraryLoads</key><true/></dict>
6: In AppDelegate.h add the below property
@property (weak, nonatomic) UIViewController *paymentOptionVC;
7: suppose you want to integrate into some class lets checkout class (example)
8: do some changes in .h file of checkout class
#import <UIKit/UIKit.h>
#import “PUUIBaseVC.h”
@interface checkout: PUUIBaseVC
9: Here I am giving .m file of checkout class .

10: above value is dummy data for testing purpose.
11: Now I am attaching two file for generating Hash Value , here i am using for only dummy checking so if you want to configure for live payment then you have to write your server file for generating HASH VALUE.

12: Now its works fine and you can set according to your need.
