Set Express Checkout and Reference Transaction for iOS

---

PayPal Developers (https://developer.paypal.com) has an amazing Native SDK for mobile development. But you can only add and use it on your project, if users have already a PayPal account. It's ok for most of countries in the world, but not in Brazil, because there are so many brazilians that don't have a PayPal account yet. So if you want to use PayPal in countries such as Brazil, you need to use SetExpressCheckout and ReferenceTransaction.

I create the this project to integrate PayPal in one of my App. So, I hope this work help other developers to easily add PayPal to their iOS App.

1 - Copy PayPal.h and PayPal.m to your project and import PayPal Class to your UIViewController

#import PayPal.h

2 - Set your PayPay USER, SIGNATURE and PASSWORD

-(void)viewDidLoad
{
    [super viewDidLoad];

    //Set Paypal Info
    PayPal *paypal = [PayPal sharedInstance];
    paypal.sandbox = YES;
    paypal.delegate = self;

    //Add your CUSTOM PayPal User, Signature and Password
    paypal.user = @"ADD_HERE_YOUR_PAYPAL_USER";
    paypal.signature = @"ADD_HERE_YOUR_PAYPAL_SIGNATURE";
    paypal.password = @"ADD_HERE_YOUR_PAYPAL_PASSWORD";
}

3 - Set Product info, total price and start the proccess

- (IBAction)buy:(id)sender
{
    //Create Fake Product 1
    NSDictionary *product1 = @{@"L_PAYMENTREQUEST_0_NAME0":@"Item A",
                               @"L_PAYMENTREQUEST_0_DESC0":@"Produto A – 110V",
                               @"L_PAYMENTREQUEST_0_AMT0":@"12.00",
                               @"L_PAYMENTREQUEST_0_QTY0":@"1"};
    
    
    //Create Fake Product 2
    NSDictionary *product2 = @{@"L_PAYMENTREQUEST_0_NAME1":@"Item B",
                               @"L_PAYMENTREQUEST_0_DESC1":@"Produto B – 220V",
                               @"L_PAYMENTREQUEST_0_AMT1":@"11.00",
                               @"L_PAYMENTREQUEST_0_QTY1":@"1"};
    //Set total
    self.totalValue = 23.00;
    
    //Add Product to PayPal
    PayPal *paypal = [PayPal sharedInstance];
    paypal.products = @[product1, product2];
    
    //Start the process
    if ([paypal isReferenceTransactionEnabled])
    {
        paypal.payment = [self paymentWithAmount:self.totalValue];
        [paypal requestReferenceTransaction];
    }
    else
    {
        //Add URLs
        paypal.returnURL = @"ADD_HERE_SUCCESS_URL";
        paypal.cancelURL = @"ADD_HERE_CANCEL_URL";
        
        paypal.payment = [self paymentWithAmount:0.00];
        [paypal requestSetCheckoutExpress];
    }
}

4 - Use Delegate Methods to get request status

There is a working example project, so you will be able to test it. It's super simple to use. I hope you guys enjoy.
