"iOS8.1就已經(jīng)有這個功能了，只是木有現(xiàn)在這么的火，現(xiàn)在的趨勢是要火的節(jié)奏，因此很多電商平臺B2B,P2P,C2C,X2X都有可能需要這個屌絲的付款功能了，在此簡單的研究一下。"
第一步先修改target為iOS 8.1，當(dāng)然支持中國的需要9.2以上且需要iPhone6以上了，然后在項目Capabilities里將Apple Pay設(shè)置為on，這將自動導(dǎo)入需要的庫文件，然后添加一個權(quán)限文件并設(shè)置，最后修改或創(chuàng)建你的App ID。

正如上圖提示的一樣，你可能會注意到上面沒有有效的Merchant ID，我們需要創(chuàng)建一個，訪問蘋果iOS 開發(fā)者中心的位于Identifiers > Merchant ID的頁面。然后隨著流程指引，創(chuàng)建一個Merchant ID并注冊它。這個和其他證書差不多再此不做過多的闡述。下圖是已經(jīng)創(chuàng)建好的參考圖片。
下載安裝然后刷新下剛剛項目里面的界面，選擇打勾即可，可以看到如下圖

下面簡單說下代碼：
.h文件里面
#import <UIKit/UIKit.h>
#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 ----支付狀態(tài)
- (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(@"支付失敗");
}
}
#pragma mark ----開始支付
- (void)ApplePay{
if([PKPaymentAuthorizationViewController canMakePayments]) {
NSLog(@"支持支付");
PKPaymentRequest *request = [[PKPaymentRequest alloc] init];
PKPaymentSummaryItem *widget1 = [PKPaymentSummaryItem summaryItemWithLabel:@"雞蛋"
amount:[NSDecimalNumber decimalNumberWithString:@"0.99"]];
PKPaymentSummaryItem *widget2 = [PKPaymentSummaryItem summaryItemWithLabel:@"蘋果"
amount:[NSDecimalNumber decimalNumberWithString:@"1.00"]];
PKPaymentSummaryItem *widget3 = [PKPaymentSummaryItem summaryItemWithLabel:@"2個蘋果"
amount:[NSDecimalNumber decimalNumberWithString:@"2.00"]];
PKPaymentSummaryItem *widget4 = [PKPaymentSummaryItem summaryItemWithLabel:@"總金額" amount:[NSDecimalNumber decimalNumberWithString:@"3.99"] type:PKPaymentSummaryItemTypeFinal];
request.paymentSummaryItems = @[widget1, widget2, widget3, widget4];
request.countryCode = @"CN";
request.currencyCode = @"CHW";
//此屬性限制支付卡，可以支付。PKPaymentNetworkChinaUnionPay支持中國的卡 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 // 支持借記卡
*/
request.merchantCapabilities = PKMerchantCapabilityCredit;
//增加郵箱及地址信息
request.requiredBillingAddressFields = PKAddressFieldEmail | PKAddressFieldPostalAddress;
PKPaymentAuthorizationViewController *paymentPane = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:request];
paymentPane.delegate = self;
if (!paymentPane) {
NSLog(@"出問題了");
}
[self presentViewController:paymentPane animated:YES completion:nil];
} else {
NSLog(@"該設(shè)備不支持支付");
}
}
#pragma mark ----支付完成
- (void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller
{
[controller dismissViewControllerAnimated:TRUE completion:nil];
}
@end
在此過程中你可能會遇到如下問題：
1.countryCode 不知道怎么查，我這寫的是中國的countryCode查詢網(wǎng)站
2.currencyCode 不會查，到目前為止，我也沒搞懂，在錯誤信息里面提示一堆，隨便選的一個。
其他我認(rèn)為比較重要的屬性，請詳細(xì)看Demo具體效果圖如下：
上圖皆為模擬器
