iOS应用程序内购/内付费

接下来就是代码部分啦~

1.首先在项目工程中加入“storekit.framework”，加入头文件#import <StoreKit/StoreKit.h>

2.在.h文件中加入“SKPaymentTransactionObserver,SKProductsRequestDelegate”监听机制

下面贴上内购的核心代码，就几个函数，我在这边就不在做更多详细的解释了，各位看官可以运行跑一下就一目了然了。

.h文件

#import <UIKit/UIKit.h>

#import <StoreKit/StoreKit.h>

@interface PaymentViewController : UIViewController<SKPaymentTransactionObserver,SKProductsRequestDelegate>

@property (strong, nonatomic) IBOutlet UITextField *productID;

@property (strong, nonatomic) IBOutlet UIButton *purchase;

- (IBAction)purchaseFunc:(id)sender;

@end

#import "PaymentViewController.h"

@interface PaymentViewController ()

@end

@implementation PaymentViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    self.productID.text = @"com.games.ztyxs.product_point.1";
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)purchaseFunc:(id)sender {
    NSString *product = self.productID.text;
    if([SKPaymentQueue canMakePayments]){
        [self requestProductData:product];
    }else{
        NSLog(@"不允许程序内付费");
    }
}

//请求商品
- (void)requestProductData:(NSString *)type{
    NSLog(@"-------------请求对应的产品信息----------------");

    NSSet *nsset = [NSSet setWithArray:product];
    SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:nsset];
    request.delegate = self;
    [request start];
    
}

//收到产品返回信息
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{

    NSLog(@"--------------收到产品反馈消息---------------------");
    NSArray *product = response.products;
    if([product count] == 0){
        NSLog(@"--------------没有商品------------------");
        return;
    }
    
    NSLog(@"productID:%@", response.invalidProductIdentifiers);
    NSLog(@"产品付费数量:%d",[product count]);
    
    SKProduct *p = nil;
    for (SKProduct *pro in product) {
        NSLog(@"%@", [pro description]);
        NSLog(@"%@", [pro localizedTitle]);
        NSLog(@"%@", [pro localizedDescription]);
        NSLog(@"%@", [pro price]);
        NSLog(@"%@", [pro productIdentifier]);
        
        if([pro.productIdentifier isEqualToString:self.productID.text]){
            p = pro;
        }
    }
    
    SKPayment *payment = [SKPayment paymentWithProduct:p];
    
    NSLog(@"发送购买请求");
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

//请求失败
- (void)request:(SKRequest *)request didFailWithError:(NSError *)error{
    NSLog(@"------------------错误-----------------:%@", error);
}

- (void)requestDidFinish:(SKRequest *)request{
    NSLog(@"------------反馈信息结束-----------------");
}


//监听购买结果
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transaction{
    for(SKPaymentTransaction *tran in transaction){
        
        switch (tran.transactionState) {
            case SKPaymentTransactionStatePurchased:
                NSLog(@"交易完成");
                
                break;
            case SKPaymentTransactionStatePurchasing:
                NSLog(@"商品添加进列表");
                
                break;
            case SKPaymentTransactionStateRestored:
                NSLog(@"已经购买过商品");
            
                break;
            case SKPaymentTransactionStateFailed:
                NSLog(@"交易失败");
                
                break;
            default:
                break;
        }
    }
}

//交易结束
- (void)completeTransaction:(SKPaymentTransaction *)transaction{
    NSLog(@"交易结束");
    
    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}


- (void)dealloc{
    [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
    [super dealloc];
}

代码就这么多，到这边我们的IOS内购教程就接近尾声了，在测试的时候还有几点因素要注意一下：

1.沙盒环境测试appStore内购流程的时候，请使用没越狱的设备。

2.请务必使用真机来测试，一切以真机为准。

3.项目的Bundle identifier需要与您申请AppID时填写的bundleID一致，不然会无法请求到商品信息。

讲了这么多，附上几张测试截屏给大家展示一下：
