objective-c - 为应用内购买实现一种以上的购买类型
<p><p>这是根据建议使用 Apple 文档编辑的表单。
我用 2 个独立的 IBAction 创建了 2 个独立的按钮。</p>
<pre><code>UIButton *buyCredit1 = ;
buyCredit1.frame = scrollViewFrame;
;
buyCredit1.tag = 10;
;
[buyCredit1 addTarget:self
action:@selector(purchase10credit:)
forControlEvents:UIControlEventTouchUpInside];
UIButton *buyCredit2 = ;
buyCredit2.frame = scrollViewFrame;
;
buyCredit2.tag = 30;
;
[buyCredit2 addTarget:self
action:@selector(purchase30credit:)
forControlEvents:UIControlEventTouchUpInside];
-(IBAction)purchase10credit:(id)sender{
SKMutablePayment *payment = [ init];
payment.productIdentifier = @"Bundle.10.credits";
[ addPayment:payment];
[ addTransactionObserver:self];
[ addPayment:payment];
}
-(IBAction)purchase30credit:(id)sender{
SKMutablePayment *payment = [ init];
payment.productIdentifier = @"Bundle.30.credits";
[ addPayment:payment];
[ addTransactionObserver:self];
[ addPayment:payment];
}
-(void) productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
SKProduct *validProduct = nil;
int count = ;
if (count > 0) {
validProduct = ;
}
else if (!validProduct) {
NSLog(@"No Products Available");
}
}
</code></pre>
<p>这是 Apple 反射(reflect)的应用内购买文档</p>
<pre><code>-(void) productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
SKProduct *validProduct = nil;
int count = ;
if (count > 0) {
validProduct = ;
}
else if (!validProduct) {
NSLog(@"No Products Available");
}
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
for (SKPaymentTransaction *transaction in transactions)
{
switch (transaction.transactionState)
{
case SKPaymentTransactionStatePurchased:
;
break;
case SKPaymentTransactionStateFailed:
;
break;
case SKPaymentTransactionStateRestored:
;
default:
break;
}
}
}
- (void) updateCredit: (NSString *)productIdentifier {
//Adding to plist
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = ;
NSString *path = ;
NSMutableArray *currPlist = [ initWithContentsOfFile: path];
NSString *lastEx = ;
int lastScore = [ intValue];
int numberOfTries = [ intValue];
int totalScore = [ intValue];
int avg = [ intValue];
int credit = [ intValue];
credit += 10;
NSString *currentCredit = ;
creditShow.text = currentCredit;
NSMutableArray *updatePlist = [ init];
;
];
];
];
];
];
;
}
- (void) completeTransaction: (SKPaymentTransaction *)transaction
{
// Your application should implement these two methods.
;
// Remove the transaction from the payment queue.
[ finishTransaction: transaction];
}
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
[ finishTransaction: transaction];
}
- (void) failedTransaction: (SKPaymentTransaction *)transaction
{
if (transaction.error.code != SKErrorPaymentCancelled) {
// Optionally, display an error here.
}
[ finishTransaction: transaction];
}
</code></pre>
<p>在 - (void) updateCredit: (NSString *)productIdentifier 中，我如何创建 2 个单独的信用更新？ 1 个积分 += 10(购买 0.99 美分，积分 += 30(1.99 美元)？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>检查 <code>purchase:</code> 中的 (id)sender 并确定按下了哪个按钮(您可以为按钮设置标签属性，例如 tag=1 表示 10 个积分，tag=5 表示50 学分)。然后您可以设置另一个应用内购买:</p>
<pre><code>UIButton *tempButton = (UIButton *)sender;
if (tempButton.tag == 1)
payment.productIdentifier = @"Bundle.10.credits";
else
payment.productIdentifier = @"Bundle.50.credits";
</code></pre>
<p>至于更新状态是推荐的方式:</p>
<pre><code>- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
for (SKPaymentTransaction *transaction in transactions)
{
switch (transaction.transactionState)
{
case SKPaymentTransactionStatePurchased:
;
break;
case SKPaymentTransactionStateFailed:
;
break;
case SKPaymentTransactionStateRestored:
;
default:
break;
}
}
}
- (void) completeTransaction: (SKPaymentTransaction *)transaction
{
// Your application should implement these two methods.
;
;
// Remove the transaction from the payment queue.
[ finishTransaction: transaction];
}
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
;
;
[ finishTransaction: transaction];
}
- (void) failedTransaction: (SKPaymentTransaction *)transaction
{
if (transaction.error.code != SKErrorPaymentCancelled) {
// Optionally, display an error here.
}
[ finishTransaction: transaction];
}
</code></pre>
