Apple Pay 应用 demo --备用哦

"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 [UIKit/UIKit.h]（因识别问题，此处将尖括号改为方括号）
#import [PassKit/PassKit.h]
@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。

3.木有iPhone6手机，我就是其中之一…….

其他我认为比较重要的属性，请详细看Demo具体效果图如下：
