感谢在这里帮助过我的所有人！我终于成功了。
我得到了一个不同的代码。我将尝试解释我在这里所做的一切，以便如果有人想做同样的事情。
首先在 iOS Provisioning Portal 上创建 App ID，并在 iTunes Connect 上创建 IAP 购买。
然后，获取这个项目：http://xcodenoobies.blogspot.com.br/2012/04/implementing-inapp-purchase-in-xcode.html 并导入“SFHFKeychainUtils.h”和 .m 文件。不要忘记将 SFHFKeychainUtils.m 添加到您的编译源（项目 -> 构建阶段 -> 编译源）。
现在是代码：
.h
#import <StoreKit/StoreKit.h>
(...)
<SKProductsRequestDelegate, SKPaymentTransactionObserver, UIAlertViewDelegate> {
IBOutlet UIButton *feature2Btn;
IBOutlet UILabel *featureLabel, *statusLabel;
UIAlertView *askToPurchase;
int64_t coins;
IBOutlet UILabel * coinsLabel;
}
@property (nonatomic, retain) UIButton *feature2Btn;
@property (nonatomic, retain) UILabel *featureLabel, *statusLabel;
@property (nonatomic, assign) int64_t coins;
-(IBAction)button10Coins:(id)sender;
-(BOOL)IAPItemPurchased;
.m
#import "SFHFKeychainUtils.h"
@synthesize feature2Btn, featureLabel, statusLabel, coins;
#define kStoredData @"com.IAPID.10coins"
按钮：
-(IBAction)button10Coins:(id)sender {
askToPurchase = [[UIAlertView alloc]
initWithTitle:@"IAP"
message:@"Would you like to buy 10 coins?"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Yes", @"No", nil];
askToPurchase.delegate = self;
[askToPurchase show];
}
检查 IAP 是否可用：
#pragma mark AlertView Delegate
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (alertView==askToPurchase) {
if (buttonIndex==0) {
// user tapped YES, but we need to check if IAP is enabled or not.
if ([SKPaymentQueue canMakePayments]) {
NSLog(@"IAP: Checking if IAP Available");
SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:@"com.IAPID.10coins"]];
request.delegate = self;
[request start];
} else {
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Prohibited"
message:@"Parental Control is enabled, cannot make a purchase!"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Ok", nil];
[tmp show];
}
}
} }
请求产品（如果有），或者取消购买（如果没有）：
-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
NSLog(@"IAP: Received Response");
// remove wait view here
statusLabel.text = @"";
SKProduct *validProduct = nil;
int count = [response.products count];
if (count>0) {
NSLog(@"IAP: Available, starting transaction");
validProduct = [response.products objectAtIndex:0];
SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.IAPID.10coins"];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
} else {
NSLog(@"IAP: Item not found");
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Internet Connection Required"
message:@"You must connect to a Wi-Fi or cellular data network to perform an In-App Purchase."
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Ok", nil];
[tmp show];
} }
最后，动作：
#pragma mark StoreKit Delegate
-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
for (SKPaymentTransaction *transaction in transactions) {
switch (transaction.transactionState) {
case SKPaymentTransactionStatePurchasing: {
// show wait view here
NSLog(@"IAP: Processing...");}
break;
case SKPaymentTransactionStatePurchased:{
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
// remove wait view and unlock feature 2
statusLabel.text = @"Done!";
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Completet"
message:@"The purchase has been completed!"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Ok", nil];
[tmp show];
NSError *error = nil;
[SFHFKeychainUtils storeUsername:@"IAPNoob01" andPassword:@"whatever" forServiceName:kStoredData updateExisting:YES error:&error];
// apply purchase action - hide lock overlay and
[feature2Btn setBackgroundImage:nil forState:UIControlStateNormal];
// Get The Coins, rock, favor points, whatever:
self.coins = coins +10;
coinsLabel.text = [NSString stringWithFormat: @"%lld", self.coins];
}
break;
case SKPaymentTransactionStateRestored:{
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
// remove wait view here
statusLabel.text = @"";}
break;
case SKPaymentTransactionStateFailed:{
if (transaction.error.code != SKErrorPaymentCancelled) {
NSLog(@"Error payment cancelled");
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
// remove wait view here
statusLabel.text = @"Purchase Error!";}
break;
default:
break;
}
} }
不太确定是否必须添加这个：
-(void)requestDidFinish:(SKRequest *)request {
}
-(void)request:(SKRequest *)request didFailWithError:(NSError *)error {
NSLog(@"Failed to connect with error: %@", [error localizedDescription]);
}
这是有史以来最简单的代码。不确定Apple是否会批准，但它正在工作。这适用于 iOS 4.3 及更高版本，我认为它很棒，但没有实现收据，因此一些聪明的孩子将能够免费获得硬币。
不要忘记在 iTunes Connect 上创建 Consumable 项目，并将 ID“com.IAPID.10coins”更改为您在那里创建的正确 ID。
“paymentWithProductIdentifier”已弃用，但仍然有效，要修复它，请将其更改为“paymentWithProduct”并找到添加 IAP ID 的方法。我试过但没有成功。
这是 ARC 准备好了，除了“SFHFKeychainUtils.m”，你可以尝试修复它或在该单个文件上禁用 ARC，这里是教程：http://www.leesilver.net/1/post/2011/8/disabling-arc-on-certain-files-in-xcode.html
您还必须将 ScoreKit 和安全框架添加到您的项目中。
对于消耗品，就是这样！对于非消耗品，您必须添加一个 RESTORE 按钮，否则 Apple 会拒绝您。但这很容易：
// RESTORE
- (IBAction)IAPRestore:(id)sender
{
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
- (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
NSLog(@"Restore completed transactions finished.");
NSLog(@" Number of transactions in queue: %d", [[queue transactions] count]);
for (SKPaymentTransaction *trans in [queue transactions])
{
NSLog(@" transaction id %@ for product %@.", [trans transactionIdentifier], [[trans payment] productIdentifier]);
NSLog(@" original transaction id: %@ for product %@.", [[trans originalTransaction] transactionIdentifier],
[[[trans originalTransaction] payment]productIdentifier]);
if ([[[trans payment] productIdentifier] isEqual: @"com.AppID.IAPID"]) {
NSLog(@"Purchase Restored");
// Do your stuff to unlock
}
}
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Purchases Restored"
message:@"Your previously purchased products have been restored!"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"OK", nil];
[tmp show];
}
我希望这对某人有用并且 Apple 批准它:)
更新：Apple 批准了它，销售情况良好，iOS 4.3、5 和 6 销售正常 :)
UPDATE2：在 Xcode 4.6 和 iOS 6.1.2 上测试并完美运行。
