前言

大家都知道，ios虚拟商品如宝石、金币等都需要走内购，和苹果三七分成，如果这类商品不走内购那么上不去架或者上架以后被发现而被下架。最近有一个项目需要增加内购支付功能，所以最近又重新集成并整理了下，希望对大家有所帮助。感兴趣的可以参考上面几篇。
1. iOS内购IAP（一） —— 基础配置篇(一)

实现详情

这里ios开发平台上的证书和税务等基础配置我就不说了，不明白的可以参考为的另外一篇文章ios内购之基础配置篇。这一篇的重点就是说一下我在项目中的具体实现，将抽象进一步具体化。

一、增加内购项目

在开发者账号itunesConnect--我的app中增加内购项目，如下图所示。

增加内购项目

细心的朋友可能发现，我这里状态中有的是已删除，有的是元数据丢失，这是怎么回事呢？这里我要和大家说一下，这里提示已删除的是因为我有的信息填错了，后来让我在这里删除了；而下面的元数据丢失是因为，在增加内购项目的时候，没有填写完全，比如screenshot我就没有填写，这里就显示了元数据丢失。这里还有一点需要提醒大家，产品ID是唯一的，假如你增加的内购项目删除了，那么这个产品ID就不能用了，你下边就是增加再多的内购项目也不能使用这个删除的产品ID了，所以填写要慎重。还要就是别忘记添加沙盒测试人员账号，不会的同样参考我上面的文章。还有就是这里的价格是根据内购的一个价格表定的，这里不支持自定义价格。

二、代码集成

下面我就只要说一下内购项目的代码及其逻辑。不废话，我就直接上代码了。

JJMoneyChargeVC.m文件

//增加头文件
#import "StoreKit/StoreKit.h"

//必要的几个属性
@property (nonatomic, strong) SKProductsRequest *productRequest;
@property (nonatomic, copy) NSString *productID;
@property (nonatomic, copy) NSString *chargeMoneyNumStr;
@property (nonatomic, copy) NSString *orderIDStr;

//开启内购
- (void)viewDidLoad
{
    [super viewDidLoad];
    
    self.title = @"充值";
    
    self.view.backgroundColor = [UIColor whiteColor];
    
    [self setupUI];
    //开启内购
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    
}

//下面就是具体的方法实现了

//点击手势选择要充值的金额
- (void)tapDidTapped:(UITapGestureRecognizer *)tapGesture
{
    switch (tapGesture.view.tag) {
            
        case JJChargeVCChargeType100:
            NSLog(@"我充值100金币");
            self.chargeMoneyNumStr = @"1";
            break;
            
        case  JJChargeVCChargeType600:
            NSLog(@"我充值600金币");
            self.chargeMoneyNumStr = @"6";
            break;

            NSLog(@"我充值1800金币");
            self.chargeMoneyNumStr = @"18";
            break;
            
        case  JJChargeVCChargeType3000:
