首先介紹實現(xiàn)蘋果內(nèi)購的流程
購買
1.向蘋果服務(wù)器 請求商品列表
2.蘋果服務(wù)器 在回調(diào)中返回商品列表
3.向蘋果服務(wù)器 請求購買商品列表的第一個
4.蘋果服務(wù)器 在回調(diào)中返回購買結(jié)果
5.根據(jù)回調(diào)的結(jié)果 進行處理
恢復購買
1.向蘋果服務(wù)器 請求恢復購買
2.蘋果服務(wù)器 在回調(diào)中返回恢復購買結(jié)果
5.根據(jù)回調(diào)的結(jié)果 進行處理
下面是代碼實現(xiàn)
下面是.h文件的實現(xiàn)
#import <Foundation/Foundation.h>
NS_ASSUME_NONNULL_BEGIN
@interface PQIAPManager : NSObject
+ (PQIAPManager *)sharedManager;
/**請求購買商品*/
- (void)requestProductWithId:(NSString *)productId;
/**請求恢復購買*/
- (void)restore;
@end
NS_ASSUME_NONNULL_END
下面是.m文件的實現(xiàn)
#import "PQIAPManager.h"
#import <StoreKit/StoreKit.h>
#import <AppTrackingTransparency/AppTrackingTransparency.h>
#import <AdSupport/AdSupport.h>
/**共享密鑰*/
#define KSecretKey @""
/**憑證校驗地址*/
#define KReceiptCheckUrl @""
/**訂閱狀態(tài)檢驗地址*/
#define KStateCheckUrl @""
@interface PQIAPManager()<SKPaymentTransactionObserver,SKProductsRequestDelegate,SKRequestDelegate>
// 交易是否結(jié)束
@property (nonatomic, assign) BOOL isRequestFinished;
// 判斷是購買還是恢復
@property (nonatomic, assign) BOOL isRestore;
@end
@implementation PQIAPManager
// 單例
+ (instancetype)sharedManager{
static dispatch_once_t pred;
static PQIAPManager *manager = nil;
dispatch_once(&pred, ^{
manager = [[self alloc] init];
});
return manager;
}
// 創(chuàng)建時就開始監(jiān)聽購買事件
- (instancetype)init{
if (self = [super init]) {
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
self.isRequestFinished = YES;
}
return self;
}
// 銷毀時就移除監(jiān)聽事件
- (void)dealloc{
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
}
繼續(xù)在.m文件中添加方法
/**請求商品列表*/
- (void)requestProductWithId:(NSString *)productId {
self.isRestore = NO;

本篇主要講述了一個詳細的內(nèi)購流程及代碼實現(xiàn)，感興趣的給個贊或者關(guān)注~~~
