【问题描述】：

我想在我的 ios 应用中使用 Braintree API。

我的应用用于出租目的，即请求者用户必须向他想要出租的资产的所有者付款。

我检查了以下链接： http://www.youtube.com/watch?v=s7GlgBFM20I

https://www.braintreepayments.com/developers

http://www.youtube.com/watch?v=2y8Tsml6JYo

https://www.braintreepayments.com/braintrust/venmo-touch-screencasts-add-one-touch-payments-to-your-app-in-15-minutes 等等

但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 将金额支付给注册的用户电子邮件。

与我在 Braintree Payment API 中搜索的内容相同。

非常感谢任何帮助。

提前致谢。

我正在使用下面的代码：（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 
    // Create a dictionary of POST data of the format
    // "payment_method_code": "[encrypted payment_method_code data from Venmo Touch client]"
    NSMutableDictionary *paymentInfo = [NSMutableDictionary dictionaryWithObject:paymentMethodCode
                                                                          forKey:@"payment_method_code"];
    [self savePaymentInfoToServer:paymentInfo]; // send card through your server to Braintree Gateway


#define SAMPLE_CHECKOUT_BASE_URL @"http://venmo-sdk-sample-two.herokuapp.com"
//#define SAMPLE_CHECKOUT_BASE_URL @"http://localhost:4567"

// 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
- (void) savePaymentInfoToServer:(NSDictionary *)paymentInfo 

    NSURL *url;
    if ([paymentInfo objectForKey:@"payment_method_code"]) 
        url = [NSURL URLWithString: [NSString stringWithFormat:@"%@/card/payment_method_code", SAMPLE_CHECKOUT_BASE_URL]];
     else 
        url = [NSURL URLWithString: [NSString stringWithFormat:@"%@/card/add", SAMPLE_CHECKOUT_BASE_URL]];
    
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];

    // You need a customer id in order to save a card to the Braintree vault.
    // Here, for the sake of example, we set customer_id to device id.
    // In practice, this is probably whatever user_id your app has assigned to this user.
    NSString *customerId = [[UIDevice currentDevice] identifierForVendor].UUIDString;
    [paymentInfo setValue:customerId forKey:@"customer_id"];

    request.HTTPBody = [self postDataFromDictionary:paymentInfo];
    request.HTTPMethod = @"POST";

    [NSURLConnection sendAsynchronousRequest:request
                                       queue:[NSOperationQueue mainQueue]
                           completionHandler:^(NSURLResponse *response, NSData *body, NSError *requestError)
     
         NSError *err = nil;
         if (!response && requestError) 
             NSLog(@"requestError: %@", requestError);
             [self.paymentViewController showErrorWithTitle:@"Error" message:@"Unable to reach the network."];
             return;
         

         NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:body options:kNilOptions error:&err];
         NSLog(@"saveCardToServer: paymentInfo: %@ response: %@, error: %@", paymentInfo, responseDictionary, requestError);

         if ([[responseDictionary valueForKey:@"success"] isEqualToNumber:@1])  // Success!
             // Don't forget to call the cleanup method,
             // `prepareForDismissal`, on your `BTPaymentViewController`
             [self.paymentViewController prepareForDismissal];
             // Now you can dismiss and tell the user everything worked.
             [self dismissViewControllerAnimated:YES completion:^(void) 
                 [[[UIAlertView alloc] initWithTitle:@"Success" message:@"Saved your card!" delegate:nil
                                   cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
                 [[VTClient sharedVTClient] refresh];
             ];

          else  // The card did not save correctly, so show the error from server with convenenience method `showErrorWithTitle`
             [self.paymentViewController showErrorWithTitle:@"Error saving your card" message:[self messageStringFromResponse:responseDictionary]];
         
     ];

为什么要在这里投反对票？也请告诉我原因。

如果您添加一些代码来显示您正在尝试做的事情以及您遇到的问题，那么您的问题会更受欢迎。

感谢 alfasin，我还提供了我的代码 sn-p。

@Richa 我也计划在 iOS 应用中使用 Braintree。你的应用程序被苹果接受了吗？我已经阅读了很多帖子，它说该应用程序可以被拒绝，因为这超出了应用程序内购买指南。所以，我想在开始之前进行调查。提前致谢。

@AkbariDipali 有数以千计的应用程序使用 Braintree，所以这取决于你在用它做什么，而不仅仅是你在使用它。

_{我在布伦特里工作。如果您有更多问题或需要更多帮助，请联系our support team。}

Braintree iOS SDK docs 包括quickstart guide，以及有关库功能的详细信息。

如果您正在寻找有关如何在您的应用/网站用户之间进行付款的具体信息，您应该查看the marketplace guide 和Venmo APIs。

非常感谢@agf 的回答，我会查看所有这些链接。

@agf 我也计划在 iOS 应用中使用 Braintree。我读过很多帖子，它说苹果可以拒绝该应用程序，因为这超出了应用内购买指南。应用程序是否有被拒绝的可能性？在开始使用 Braintree 之前，我担心苹果对应用程序的接受度。提前致谢。

@AkbariDipali 我建议您向我们的支持团队发送电子邮件。基本上，这取决于你在卖什么。

@agf 感谢您的回复。是的，我也得到了答案，这取决于要销售的产品，根据应用程序的要求，我已经开始使用braintree :)

@agf 是否可以为 Braintree 使用自定义 cedict 卡片视图？或者我们可以只使用 Braintree 提供的 drop in 视图？
