iOS应用内购买

IOS应用内购买

简介

应用程序内购买是应用程序用于购买额外内容或升级功能。

实例步骤

1.在 iTunes 连接中请确保拥有一个唯一的 App ID（unique App ID ），当创建捆绑的ID（ bundle ID）应用程序更新时，代码会以相应的配置文件签名在Xcode上

2.创建新的应用程序和更新应用程序信息。你可以知道更多有关的，在苹果的 添加新的应用程序 文档中

3.在应用程序页的管理应用程序( Manage In-App Purchase)中，为app内付费添加新产品

4.确保设置的应用程序为的银行详细。需要将其设置为在应用程序内购买（In-App purchase）。此外在 iTunes 中使用管理用户（Manage Users）选项，创建一个测试用户帐户连接您的应用程序的页。

5.下一步是与处理代码和为我们在应用程序内购买创建有关的 UI。

6.创建一个单一的视图应用程序，并在 iTunes 中指定的标识符连接输入捆绑标识符

7.更新ViewController.xib

8.为三个标签创建IBOutlets，且将按钮分别命名为 productTitleLabel、 productDescriptionLabel、 productPriceLabel 和 purchaseButton

9.选择项目文件，然后选择目标，然后添加StoreKit.framework

10.更新ViewController.h ，如下所示

#import

#import

@interface ViewController : UIViewController< SKProductsRequestDelegate,SKPaymentTransactionObserver>

{

SKProductsRequest *productsRequest;

NSArray *validProducts;

UIActivityIndicatorView *activityIndicatorView;

IBOutlet UILabel *productTitleLabel;

IBOutlet UILabel *productDescriptionLabel;

IBOutlet UILabel *productPriceLabel;

IBOutlet UIButton *purchaseButton;

}

- (void)fetchAvailableProducts;

- (BOOL)canMakePurchases;

- (void)purchaseMyProduct:(SKProduct*)product;

- (IBAction)purchase:(id)sender;

@end

11.更新ViewController.m ，如下所示

#import "ViewController.h"

#define kTutorialPointProductID

@"com.tutorialPoints.testApp.testProduct"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad

{

[super viewDidLoad];

// Adding activity indicator

activityIndicatorView = [[UIActivityIndicatorView alloc]

initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

activityIndicatorView.center = self.view.center;

[activityIndicatorView hidesWhenStopped];

[self.view addSubview:activityIndicatorView];

[activityIndicatorView startAnimating];

//Hide purchase button initially

purchaseButton.hidden = YES;

[self fetchAvailableProducts];

}

- (void)didReceiveMemoryWarning

{

[super didReceiveMemoryWarning];

// Dispose of any resources that can be recreated.

}

-(void)fetchAvailableProducts{

NSSet *productIdentifiers = [NSSet

setWithObjects:kTutorialPointProductID,nil];

productsRequest = [[SKProductsRequest alloc]

initWithProductIdentifiers:productIdentifiers];

productsRequest.delegate = self;

[productsRequest start];

}

- (BOOL)canMakePurchases

{

return [SKPaymentQueue canMakePayments];

}

- (void)purchaseMyProduct:(SKProduct*)product{

if ([self canMakePurchases]) {

SKPayment *payment = [SKPayment paymentWithProduct:product];

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

[[SKPaymentQueue defaultQueue] addPayment:payment];

}

else{

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:

@"Purchases are disabled in your device" message:nil delegate:

self cancelButtonTitle:@"Ok" otherButtonTitles: nil];

[alertView show];

}

}

-(IBAction)purchase:(id)sender{

[self purchaseMyProduct:[validProducts objectAtIndex:0]];

purchaseButton.enabled = NO;

}

#pragma mark StoreKit Delegate

-(void)paymentQueue:(SKPaymentQueue *)queue

updatedTransactions:(NSArray *)transactions {

for (SKPaymentTransaction *transaction in transactions) {

switch (transaction.transactionState) {

case SKPaymentTransactionStatePurchasing:

NSLog(@"Purchasing");

break;

case SKPaymentTransactionStatePurchased:

if ([transaction.payment.productIdentifier

isEqualToString:kTutorialPointProductID]) {

NSLog(@"Purchased ");

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:

@"Purchase is completed succesfully" message:nil delegate:

self cancelButtonTitle:@"Ok" otherButtonTitles: nil];

[alertView show];

}

[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

break;

case SKPaymentTransactionStateRestored:

NSLog(@"Restored ");

[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

break;

case SKPaymentTransactionStateFailed:

NSLog(@"Purchase failed ");

break;

default:

break;

}

}

}

-(void)productsRequest:(SKProductsRequest *)request

didReceiveResponse:(SKProductsResponse *)response

{

SKProduct *validProduct = nil;

int count = [response.products count];

if (count>0) {

validProducts = response.products;

validProduct = [response.products objectAtIndex:0];

if ([validProduct.productIdentifier

isEqualToString:kTutorialPointProductID]) {

[productTitleLabel setText:[NSString stringWithFormat:

@"Product Title: %@",validProduct.localizedTitle]];

[productDescriptionLabel setText:[NSString stringWithFormat:

@"Product Desc: %@",validProduct.localizedDescription]];

[productPriceLabel setText:[NSString stringWithFormat:

@"Product Price: %@",validProduct.price]];

}

} else {

UIAlertView *tmp = [[UIAlertView alloc]

initWithTitle:@"Not Available"

message:@"No products to purchase"

delegate:self

cancelButtonTitle:nil

otherButtonTitles:@"Ok", nil];

[tmp show];

}

[activityIndicatorView stopAnimating];

purchaseButton.hidden = NO;

}

@end

注意： 需要修改你创建In-App Pur（应用内购买）的 kTutorialPointProductID 。通过修改fetchAvailableProducts产品标识符的 NSSet, 你可以添加多个产品。
