【01】针对客户详细信息开发苹果客户端object-c语言完整详细包含产品查询，购买，交易验证和恢复购买功能的完整实例-优雅草卓伊凡引言 此前由于卓伊凡我发布过关于苹果ios上架中 in -purchase 苹果内购问题 得到客户咨询来处理，苹果内购相关问题，现在讲demo写出如下，客户是采用object-c 开发的苹果客户端。 实战目前已经配置好的后台 目前已经配置的积分，对应的商品金额 以下是一个详细的 Objective-C 内购实现示例，包含产品查询、购买、交易验证和恢复购买功能： // InAppPurchaseManager.h#import <Foundation/Foundation.h>#import <StoreKit/StoreKit.h>NS_ASSUME_NONNULL_BEGINextern NSString *const IAPManagerProductPurchasedNotification;extern NSString *const IAPManagerProductPurchaseFailedNotification;extern NSString *const IAPManagerProductsLoadedNotification;@interface InAppPurchaseManager : NSObject <SKProductsRequestDelegate, SKPaymentTransactionObserver>+ (instancetype)sharedManager;// 查询产品信息- (void)requestProductsWithIdentifiers:(NSSet *)productIdentifiers;// 购买产品- (void)purchaseProduct:(SKProduct *)product;// 恢复购买- (void)restorePurchases;// 验证交易凭证- (void)verifyReceipt:(NSData *)receiptData;@property (nonatomic, strong) NSArray *products;@property (nonatomic, strong) NSSet *productIdentifiers;@property (nonatomic, strong) NSMutableSet *purchasedProductIdentifiers;@endNS_ASSUME_NONNULL_END// InAppPurchaseManager.m#import "InAppPurchaseManager.h"NSString *const IAPManagerProductPurchasedNotification = @"IAPManagerProductPurchasedNotification";NSString *const IAPManagerProductPurchaseFailedNotification = @"IAPManagerProductPurchaseFailedNotification";NSString *const IAPManagerProductsLoadedNotification = @"IAPManagerProductsLoadedNotification";@interface InAppPurchaseManager ()@property (nonatomic, strong) SKProductsRequest *productsRequest;@end@implementation InAppPurchaseManager+ (instancetype)sharedManager { static InAppPurchaseManager *sharedInstance = nil;
