1.導(dǎo)入第三方框架和設(shè)置支付界面

#import <PassKit/PassKit.h>
@interface ViewController ()<PKPaymentAuthorizationViewControllerDelegate>
/**支付view */
@property (weak, nonatomic) IBOutlet UIView *payView;
@end

2.設(shè)置支付框架

- (void)viewDidLoad {
    [super viewDidLoad];
    
    // 1.判斷當(dāng)前設(shè)備是否是支付蘋果支付
    if (![PKPaymentAuthorizationViewController canMakePayments]) {
        NSLog(@"當(dāng)前設(shè)備不支持APPlepay");
        self.payView.hidden = YES;
        // 判斷是否添加了銀行卡 PKPaymentNetworkChinaUnionPay 銀聯(lián)卡，在iOS9.2才支持
    } else if (![PKPaymentAuthorizationViewController canMakePaymentsUsingNetworks:@[PKPaymentNetworkVisa, PKPaymentNetworkChinaUnionPay]]){
        // 創(chuàng)建一個(gè)跳轉(zhuǎn)按鈕，當(dāng)用戶點(diǎn)擊按鈕時(shí)，跳轉(zhuǎn)到添加銀行卡界面
        PKPaymentButton *button = [PKPaymentButton buttonWithType:PKPaymentButtonTypeSetUp style:PKPaymentButtonStyleWhiteOutline];
        [button addTarget:self action:@selector(addCard) forControlEvents:UIControlEventTouchUpInside];
        [self.payView addSubview:button];
    } else {
        // 創(chuàng)建一個(gè)購(gòu)買按鈕，當(dāng)用戶點(diǎn)擊按鈕時(shí)，購(gòu)買一個(gè)商品
        PKPaymentButton *button = [PKPaymentButton buttonWithType:PKPaymentButtonTypeBuy style:PKPaymentButtonStyleBlack];
        [button addTarget:self action:@selector(buy) forControlEvents:UIControlEventTouchUpInside];
    }  
}

3.添加銀聯(lián)卡設(shè)置

// 跳轉(zhuǎn)到添加銀行卡界面 添加銀行卡需在真機(jī)，模擬器不行
- (void)addCard
{
    PKPassLibrary *pl = [[PKPassLibrary alloc] init];
    [pl openPaymentSetup];
}

4.購(gòu)買商品

// 購(gòu)買商品
- (void)buy
{
    NSLog(@"購(gòu)買商品");
    
    // 1.創(chuàng)建一個(gè)請(qǐng)求支付
    PKPaymentRequest *request = [[PKPaymentRequest alloc] init];
    // 2.配置支付請(qǐng)求
    //   2.1配置商家ID
    request.merchantIdentifier = @"商家ID";
    
    //   2.2配置貨幣代碼，以及國(guó)家代碼
    request.countryCode = @"CN";
    request.currencyCode = @"CNY";
    
    //   2.3配置請(qǐng)求支持的網(wǎng)絡(luò)
    request.supportedNetworks = @[PKPaymentNetworkVisa, PKPaymentNetworkChinaUnionPay];
    
    //   2.4配置商戶的處理方式
    request.merchantCapabilities = PKMerchantCapability3DS;
    //   2.5配置購(gòu)買的商品列表
    NSDecimalNumber *price = [NSDecimalNumber decimalNumberWithString:@"100.00"];
    PKPaymentSummaryItem *item1 = [PKPaymentSummaryItem summaryItemWithLabel:@"保溫杯" amount:price];
    NSDecimalNumber *prices = [NSDecimalNumber decimalNumberWithString:@"100.00"];
    PKPaymentSummaryItem *item2 = [PKPaymentSummaryItem summaryItemWithLabel:@"商家" amount:prices];
    //   注意：支付列表最后一個(gè)，代表匯總
    request.paymentSummaryItems = @[item1, item2];
    
    // 3.配置請(qǐng)求的附加項(xiàng)
    //   3.1是否顯示發(fā)票收貨地址，顯示哪些選項(xiàng)
    request.requiredBillingAddressFields = PKAddressFieldAll;
    //   3.2是否顯示快遞地址，顯示哪些選項(xiàng)
    request.requiredShippingAddressFields = PKAddressFieldAll;
    
    // 4.配置快遞方式
    //   4.1快遞費(fèi)用
    NSDecimalNumber *p1 = [NSDecimalNumber decimalNumberWithString:@"15.00"];
    PKShippingMethod *method = [PKShippingMethod summaryItemWithLabel:@"順風(fēng)快遞" amount:p1];
    method.detail = @"送貨上門";
    method.identifier = @"shunfeng";
    request.shippingMethods = @[method];
    //   4.2配置快遞的類型
    request.shippingType = PKShippingTypeStorePickup;
    
    //   4.3添加一些附加數(shù)據(jù)
    request.applicationData = [@"buyID=123456789" dataUsingEncoding:NSUTF8StringEncoding];
    
    // 5.驗(yàn)證用戶的支付授權(quán)
    PKPaymentAuthorizationViewController *avc = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:request];
    avc.delegate = self;// 注意：需遵守PKPaymentAuthorizationViewControllerDelegate方法
    [self presentViewController:avc animated:YES completion:nil];
}

5.代理方法

#pragma mark - PKPaymentAuthorizationViewControllerDelegate方法
/**
 *  如果用戶授權(quán)成功，就會(huì)調(diào)用這個(gè)方法
 *
 *  @param controller 授權(quán)控制器
 *  @param payment    支付對(duì)象
 *  @param completion 系統(tǒng)給定的一個(gè)回調(diào)代碼塊，來告訴系統(tǒng)當(dāng)前的支付狀態(tài)是否是成功
 */

                       didAuthorizePayment:(PKPayment *)payment
                                completion:(void (^)(PKPaymentAuthorizationStatus status))completion
{
    // 一般在此處，拿到支付信息，發(fā)送給服務(wù)器，處理完畢之后，服務(wù)器返回一個(gè)狀態(tài)，告訴客戶端是否支持成功，然后客戶端進(jìn)行處理
    BOOL isSucess = YES;
    if (isSucess) {
        completion(PKPaymentAuthorizationStatusSuccess);
    } else {
        completion(PKPaymentAuthorizationStatusFailure);
    }
}

// 當(dāng)用戶授權(quán)結(jié)束，或者取消授權(quán)時(shí)調(diào)用
- (void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller
{
    NSLog(@"授權(quán)結(jié)束");
    [self dismissViewControllerAnimated:controller completion:nil];
