我正在尝试在我的应用程序中使用 iap。这些是用游戏金币购买的，可以多次使用。我从菜鸟教程中编写了代码，它适用于那里的项目，有人可以告诉我我做错了什么吗？
#import "IAP.h"
#import "Money.h"
@interface IAP ()
@end
@implementation IAP;
#define kStoredData @"com.AlexApps.TinyTrucks"
+(void)myIAPWithItem:(NSString *)Item{
if ([SKPaymentQueue canMakePayments]) {
NSString *PurchaseAddress = [[NSString alloc] initWithString:[NSString stringWithFormat:@"TTE_%@kGold" , Item]];
//PurchaseAddress is the appId for this in app purchase
SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:PurchaseAddress]];
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];
}
}
#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
break;
}
case SKPaymentTransactionStatePurchased:{
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
// remove wait view and unlock feature 2
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Complete"
message:@"You have unlocked Feature 2!"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Ok", nil];
[tmp show];
// apply purchase action - hide lock overlay and
NSLog(@"befvsda");
// do other thing to enable the features
break;
}
case SKPaymentTransactionStateRestored:{
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
// remove wait view here
break;
}
case SKPaymentTransactionStateFailed:{
if (transaction.error.code != SKErrorPaymentCancelled) {
NSLog(@"Error payment cancelled");
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
// remove wait view here
break;
}
default:{
break;
}
}
}
}
-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
// remove wait view here
SKProduct *validProduct = nil;
int count = [response.products count];
if (count>0) {
validProduct = [response.products objectAtIndex:0];
SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.emirbytes.IAPNoob.01"];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
} else {
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Not Available"
message:@"No products to purchase"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Ok", nil];
[tmp show];
}
}
-(void)requestDidFinish:(SKRequest *)request
{
}
-(void)request:(SKRequest *)request didFailWithError:(NSError *)error
{
NSLog(@"Failed to connect with error: %@", [error localizedDescription]);
}
#pragma mark AlertView Delegate
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
@end
程序到达这一行：
SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:PurchaseAddress]];
request.delegate = self;
[request start];
然后它就停止了，没有从苹果那里得到任何东西。
