This SDK allows you to charge credit cards on an iOS 5 device using the Stripe API. Usage is a simple asynchronous call: #import "Stripe.h" StripeConnection *stripe = [StripeConnection connectionWithPublishableKey:@"pk_dl4LcpeAxUEPHN3FxzuAQQmhCGmx5"]; StripeCard *card = [[StripeCard alloc] init]; card.number = @"4111111111111111"; card.name = @"Bob Dylan"; card.securityCode = "010"; card.expiryMonth = [NSNumber numberWithInteger:2]; card.expiryYear = [NSNumber numberWithInteger:2014]; [stripe performRequestWithCard:card amountInCents:[NSNumber numberWithInteger:200] success:^(StripeResponse *token) { /* handle success */ } error:^(NSError *error) { /* handle failure */ }]; Please build the "example" target for an example of it in action.
