我想在我的 iOS 应用程序中使用 Braintree API。
我的应用程序用于出租目的,即请求者用户必须向他想要出租的资产所有者付款。
我检查了以下链接: http ://www.youtube.com/watch?v=s7GlgBFM20I
https://www.braintreepayments.com/developers

但是我不知道在哪里使用 Braintree 或 Venmo api 提供接收者的帐户详细信息,例如我们可以在 PayPal iOS sdk 中传递接收者的电子邮件,然后 PayPal 将金额支付给使用该电子邮件注册的用户.
我在 Braintree Payment API 中搜索的内容相同。
任何帮助是极大的赞赏。
提前致谢。
我正在使用以下代码:(来自braintree给出的示例代码)
/* Get called when user pay on Pay button on screen.
User wil see a form for entering his credit card number, CVV and expiration date. */
-(IBAction)payButtonClicked
{
self.paymentViewController =
[BTPaymentViewController paymentViewControllerWithVenmoTouchEnabled:YES];
self.paymentViewController.delegate = self;
[self presentViewController:self.paymentViewController animated:YES completion:nil];
}
// When a user types in their credit card information correctly, the BTPaymentViewController sends you
// card details via the `didSubmitCardWithInfo` delegate method.
//
// NB: you receive raw, unencrypted info in the `cardInfo` dictionary, but
// for easy PCI Compliance, you should use the `cardInfoEncrypted` dictionary
// to securely pass data through your servers to the Braintree Gateway.
- (void)paymentViewController:(BTPaymentViewController *)paymentViewController
didSubmitCardWithInfo:(NSDictionary *)cardInfo
andCardInfoEncrypted:(NSDictionary *)cardInfoEncrypted {
[self savePaymentInfoToServer:cardInfoEncrypted]; // send card through your server to Braintree Gateway
}
// When a user adds a saved card from Venmo Touch to your app, the BTPaymentViewController sends you
// a paymentMethodCode that you can pass through your servers to the Braintree Gateway to
// add the full card details to your Vault.
- (void)paymentViewController:(BTPaymentViewController *)paymentViewController
didAuthorizeCardWithPaymentMethodCode:(NSString *)paymentMethodCode {

// Pass payment info (eg card data) from the client to your server (and then to the Braintree Gateway).
// If card data is valid and added to your Vault, display a success message, and dismiss the BTPaymentViewController.
// If saving to your Vault fails, display an error message to the user via `BTPaymentViewController showErrorWithTitle`
// Saving to your Vault may fail, for example when
// * CVV verification does not pass
// * AVS verification does not pass
// * The card number was a valid Luhn number, but nonexistent or no longer valid
