繼上一篇iOS內(nèi)購圖文教程扬蕊，下面是代碼教程
創(chuàng)建一個單例類
.h文件
#import <Foundation/Foundation.h>
#import <StoreKit/StoreKit.h>
@protocol LMIAPManagerDelegate <NSObject>
@optional

//創(chuàng)建單例
+ (instancetype)sharedInstance;

.m文件
#import "ApplePayManager.h"
@interface ApplePayManager()<SKProductsRequestDelegate, SKPaymentTransactionObserver>

SKProduct *myProduct;
}
@end
@implementation ApplePayManager
//單例
+ (instancetype)sharedInstance{
static ApplePayManager *payManager = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{

});
return payManager;

在禮物頁面，調(diào)起單例事哭，添加內(nèi)購代理方法
//appleProductId 就是添加商品時填寫的ID
[[ApplePayManager sharedInstance] requestProductWithId:[NSString stringWithFormat:@"%@",model.appleProductId]];
self.hud = [MBProgressHUD showHUDAddedTo:self animated:YES];
self.hud.delegate = self;
self.hud.labelText = @"連接蘋果商店";
實現(xiàn)代理方法

[self.hud hide:YES];
} else {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"失敗" message:@"無法連接App store!" delegate:self cancelButtonTitle:@"關(guān)閉" otherButtonTitles:nil, nil];

if ([transactionReceiptString length] > 0) {
// 向自己的服務器驗證購買憑證（此處應該考慮將憑證本地保存,對服務器有失敗重發(fā)機制）
/**
服務器要做的事情:
接收ios端發(fā)過來的購買憑證。
判斷憑證是否已經(jīng)存在或驗證過瓜富，然后存儲該憑證鳍咱。
將該憑證發(fā)送到蘋果的服務器驗證，并將驗證結(jié)果返回給客戶端与柑。

//1.如果用戶購買成功之后，網(wǎng)絡突然不好价捧，無法上傳服務器丑念，會造成購買之后沒有金幣返回
//2.如果上傳服務器失敗，憑證保存在本地數(shù)組结蟋，向服務器發(fā)送請求渠欺，直至成功為止。
//3.如果購買成功之后椎眯，因某些原因APP突然閃退挠将，憑證保存在本地，應用啟動時编整，再次向服務器發(fā)送請求舔稀，直至成功為止
//4.出現(xiàn)以外情況，例如手機突然關(guān)機等掌测，提示用戶聯(lián)系客服
//5.我的做法：在mainRunLoop中添加定時器内贮，在出現(xiàn)以上狀況時，發(fā)起請求汞斧，直至數(shù)組中所有憑證上傳成功之后夜郁，移除定時器。
