iOS开发之ApplePay

"iOS8.1就已经有这个功能了，只是木有现在这么的火，现在的趋势是要火的节奏，因此很多电商平台B2B,P2P,C2C,X2X都有可能需要这个屌丝的付款功能了，在此简单的研究一下。"

第一步先修改target为iOS 8.1，当然支持中国的需要9.2以上且需要iPhone6以上了，然后在项目Capabilities里将Apple Pay设置为on，这将自动导入需要的库文件，然后添加一个权限文件并设置，最后修改或创建你的App ID。

正如上图提示的一样，你可能会注意到上面没有有效的Merchant ID，我们需要创建一个，访问苹果iOS 开发者中心的位于Identifiers > Merchant ID的页面。然后随着流程指引，创建一个Merchant ID并注册它。这个和其他证书差不多再此不做过多的阐述。下图是已经创建好的参考图片。

下载安装然后刷新下刚刚项目里面的界面，选择打勾即可，可以看到如下图

下面简单说下代码：

.h文件里面

#import 

#import 

@interface ViewController : UIViewController @end

.m文件

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];

btn.frame = CGRectMake(60, 100, 200, 50);

btn.center = self.view.center;

[btn setBackgroundImage:[UIImage imageNamed:@"ApplePayBTN_64pt__whiteLine_textLogo_"] forState:UIControlStateNormal];

[btn addTarget:self action:@selector(ApplePay) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:btn];

}

#pragma mark ----支付状态

- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller

didAuthorizePayment:(PKPayment *)payment

completion:(void (^)(PKPaymentAuthorizationStatus status))completion

{

NSLog(@"Payment was authorized: %@", payment);

BOOL asyncSuccessful = FALSE;

if(asyncSuccessful) {

completion(PKPaymentAuthorizationStatusSuccess);

// do something to let the user know the status

NSLog(@"支付成功");

} else {

completion(PKPaymentAuthorizationStatusFailure);

// do something to let the user know the status

NSLog(@"支付失败");

}

}

#pragma mark ----开始支付

- (void)ApplePay{

if([PKPaymentAuthorizationViewController canMakePayments]) {

NSLog(@"支持支付");

PKPaymentRequest *request = [[PKPaymentRequest alloc] init];

PKPaymentSummaryItem *widget1 = [PKPaymentSummaryItem summaryItemWithLabel:@"鸡蛋"

amount:[NSDecimalNumber decimalNumberWithString:@"0.99"]];

PKPaymentSummaryItem *widget2 = [PKPaymentSummaryItem summaryItemWithLabel:@"苹果"

amount:[NSDecimalNumber decimalNumberWithString:@"1.00"]];

PKPaymentSummaryItem *widget3 = [PKPaymentSummaryItem summaryItemWithLabel:@"2个苹果"

amount:[NSDecimalNumber decimalNumberWithString:@"2.00"]];

PKPaymentSummaryItem *widget4 = [PKPaymentSummaryItem summaryItemWithLabel:@"总金额" amount:[NSDecimalNumber decimalNumberWithString:@"3.99"] type:PKPaymentSummaryItemTypeFinal];

request.paymentSummaryItems = @[widget1, widget2, widget3, widget4];

request.countryCode = @"CN";

request.currencyCode = @"CHW";

//此属性限制支付卡，可以支付。PKPaymentNetworkChinaUnionPay支持中国的卡 9.2增加的

request.supportedNetworks = @[PKPaymentNetworkChinaUnionPay, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa];

request.merchantIdentifier = @"merchant.com.example.lbapplepaydemo";

/*

PKMerchantCapabilityCredit NS_ENUM_AVAILABLE_IOS(9_0)  = 1UL << 2,  // 支持信用卡

PKMerchantCapabilityDebit  NS_ENUM_AVAILABLE_IOS(9_0)  = 1UL << 3    // 支持借记卡

*/

request.merchantCapabilities = PKMerchantCapabilityCredit;

//增加邮箱及地址信息

request.requiredBillingAddressFields = PKAddressFieldEmail | PKAddressFieldPostalAddress;

PKPaymentAuthorizationViewController *paymentPane = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:request];

paymentPane.delegate = self;

if (!paymentPane) {

NSLog(@"出问题了");

}

[self presentViewController:paymentPane animated:YES completion:nil];

} else {

NSLog(@"该设备不支持支付");

}

}

#pragma mark ----支付完成

- (void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller

{

[controller dismissViewControllerAnimated:TRUE completion:nil];

}

@end

在此过程中你可能会遇到如下问题：

1.countryCode 不知道怎么查，我这写的是中国的countryCode查询网站

2.currencyCode 不会查，到目前为止，我也没搞懂，在错误信息里面提示一堆，随便选的一个。

其他我认为比较重要的属性，请详细看Demo具体效果图如下：

上图皆为模拟器
