Can I use PayPal in iPhone/iPad apps?

Question

I am working on an application that through which I want to sell some event Tickets.

Can I use PayPal for this purpose, and will Apple approve the app using other that StoreKit Framework.

I searched on this topic, but I am not able to find any possible solution.

Some searches say that paypal can be used and the other say that Apple never approves an app using payment gateway other than inAppPurchase.

Please help me!

Answer 1

Yes, you can use PayPal payment gateway with your application. You can see the complete documentation from the below link:

https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/library_documentation#mobile

Add following code in your .h File

#import "PayPal.h"
#import "PayPalList.h"

typedef enum PaymentStatuses 
{
    PAYMENTSTATUS_SUCCESS,
    PAYMENTSTATUS_FAILED,
    PAYMENTSTATUS_CANCELED,
} PaymentStatus;

Implement this delegate method "PayPalPaymentDelegate"

PayPalList *payPalList;
PaymentStatus status;

Add the following code in your .m File

#import "PayPalPayment.h"
#import "PayPalAdvancedPayment.h"
#import "PayPalAmounts.h"
#import "PayPalReceiverAmounts.h"
#import "PayPalAddress.h"
#import "PayPalInvoiceItem.h"
#define SPACING 3.

{

    UIButton *btnPayWithPayPal = [[PayPal getInstance] getPayButtonWithTarget:self andAction:action andButtonType:type];

    CGRect frame;
    frame.origin.x = 60;
    frame.origin.y = 315;
    frame.size.width = 304;
    frame.size.height = 40;

    btnPayWithPayPal.frame = frame;
    [self.view addSubview:btnPayWithPayPal];
}

Although there is an API existing for Paypal integration in iPhone but as per the Apple guidelines it'll not approve such apps for their AppStore. See Apple guidelines clause 11.3 here https://developer.apple.com/appstore/resources/approval/guidelines.html
