iOS應(yīng)用內(nèi)購買
簡介
應(yīng)用程序內(nèi)購買是應(yīng)用程序用于購買額外內(nèi)容或升級功能。
創(chuàng)新互聯(lián)從2013年創(chuàng)立，先為河源等服務(wù)建站，河源等地企業(yè)，進行企業(yè)商務(wù)咨詢服務(wù)。為河源企業(yè)網(wǎng)站制作PC+手機+微官網(wǎng)三網(wǎng)同步一站式服務(wù)解決您的所有建站問題。
實例步驟
1.在 iTunes 連接中請確保擁有一個唯一的 App ID（unique App ID ），當(dāng)創(chuàng)建捆綁的ID（ bundle ID）應(yīng)用程序更新時，代碼會以相應(yīng)的配置文件簽名在Xcode上
2.創(chuàng)建新的應(yīng)用程序和更新應(yīng)用程序信息。你可以知道更多有關(guān)的，在蘋果的 添加新的應(yīng)用程序 文檔中
3.在應(yīng)用程序頁的管理應(yīng)用程序( Manage In-App Purchase)中，為app內(nèi)付費添加新產(chǎn)品
4.確保設(shè)置的應(yīng)用程序為的銀行詳細。需要將其設(shè)置為在應(yīng)用程序內(nèi)購買（In-App purchase）。此外在 iTunes 中使用管理用戶（Manage Users）選項，創(chuàng)建一個測試用戶帳戶連接您的應(yīng)用程序的頁。
5.下一步是與處理代碼和為我們在應(yīng)用程序內(nèi)購買創(chuàng)建有關(guān)的 UI。
6.創(chuàng)建一個單一的視圖應(yīng)用程序，并在 iTunes 中指定的標識符連接輸入捆綁標識符
7.更新ViewController.xib ，如下所示
8.為三個標簽創(chuàng)建IBOutlets，且將按鈕分別命名為 productTitleLabel、 productDescriptionLabel、 productPriceLabel 和 purchaseButton
9.選擇項目文件，然后選擇目標，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：需要修改你創(chuàng)建In-App Pur（應(yīng)用內(nèi)購買）的 kTutorialPointProductID 。通過修改fetchAvailableProducts產(chǎn)品標識符的 NSSet, 你可以添加多個產(chǎn)品。
輸出
運行該應(yīng)用程序,輸出結(jié)果如下
確保已經(jīng)中登錄。單擊購買選擇現(xiàn)有的Apple ID。輸入有效的測試帳戶的用戶名和密碼。幾秒鐘后，顯示下面的信息
一旦產(chǎn)品成功購買，將獲得以下信息。可以在顯示此信息的地方，更新應(yīng)用功能相關(guān)的代碼
