我已经成功实施了一种耗材产品，但我不知道如何实施多种耗材产品。我想添加更多ProductIdentifiers，如com.lalala.20batteries，com.lalala.30batteries
任何人都可以给我一些指南
这是我的单一消费品代码
@interface ViewController () <SKProductsRequestDelegate, SKPaymentTransactionObserver>
@end
@implementation ViewController
#define ProductIdentifier @"com.lalala.10batteries"
- (IBAction)taps10batteries{
NSLog(@"User requests to get 10 batteries");
if([SKPaymentQueue canMakePayments]){
NSLog(@"User can make payments");
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:ProductIdentifier]];
productsRequest.delegate = self;
[productsRequest start];
}
else{
NSLog(@"User cannot make payments due to parental controls");
}
}
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
SKProduct *validProduct = nil;
int count = [response.products count];
if(count > 0){
validProduct = [response.products objectAtIndex:0];
NSLog(@"Products Available!");
[self purchase:validProduct];
}
else if(!validProduct){
NSLog(@"No products available");
}
}
- (IBAction)purchase:(SKProduct *)product{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
NSLog(@"received restored transactions: %i", queue.transactions.count);
for(SKPaymentTransaction *transaction in queue.transactions){
if(transaction.transactionState == SKPaymentTransactionStateRestored){
//called when the user successfully restores a purchase
NSLog(@"Transaction state -> Restored");
[self get10Batteries];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
}
}
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
for(SKPaymentTransaction *transaction in transactions){
switch(transaction.transactionState){
case SKPaymentTransactionStatePurchasing: NSLog(@"Transaction state -> Purchasing");
break;
case SKPaymentTransactionStatePurchased:
[self get10Batteries];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
NSLog(@"Transaction state -> Purchased");
break;
case SKPaymentTransactionStateRestored:
NSLog(@"Transaction state -> Restored");
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
if(transaction.error.code == SKErrorPaymentCancelled){
NSLog(@"Transaction state -> Cancelled");
//the user cancelled the payment ;(
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
}
}
}
- (void)get10Batteries{
NSUbiquitousKeyValueStore *cloudstore1 = [NSUbiquitousKeyValueStore defaultStore];
//load cloud integer
coins = [cloudstore1 doubleForKey:@"yo" ];
coins = [[NSUserDefaults standardUserDefaults]
integerForKey:@"com.lalala.10batteries"];
coins += 10;
[[NSUserDefaults standardUserDefaults] setInteger:coins
forKey:@"com.lalala.10batteries"];
[[NSUserDefaults standardUserDefaults] synchronize];
_coinLabel.text = [NSString stringWithFormat:@"%li", (long)coins];
//save icloud
[cloudstore1 setDouble:coins forKey:@"yo"];
[cloudstore1 synchronize];
}
- (void)viewDidLoad {
[super viewDidLoad];
NSUbiquitousKeyValueStore *cloudstore1 = [NSUbiquitousKeyValueStore defaultStore];
_coinLabel.text = [cloudstore1 stringForKey:@"yo" ];
NSUserDefaults *coinsdefaults = [NSUserDefaults standardUserDefaults];
if([coinsdefaults objectForKey:@"com.lalala.10batteries"] != nil) {
coins = [[NSUserDefaults standardUserDefaults] integerForKey:@"com.lalala.10batteries"];
coins = [coinsdefaults integerForKey:@"com.lalala.10batteries"];
_coinLabel.text = [NSString stringWithFormat:@"%li", (long)coins];
}
}

您的代码可以轻松支持多种产品，就像它支持一种产品一样...... 首先，声明您的其他产品ID，就像使用其中一样：
#define ProductIdentifier1 @"com.lalala.10batteries"
#define ProductIdentifier2 @"com.lalala.20batteries"
然后，创建一个loadAllProducts方法，它与taps10batteries方法完全相同，只不过您使用所有产品ID声明SKProductsRequest，就像使用一个产品ID一样：< / p>
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObjects:ProductIdentifier1, ProductIdentifier2, nil]];
除非您更喜欢单独加载每个产品，否则您需要为每个产品创建一个方法，即taps20batteries，您可以忽略我的答案的下一部分......
回调方法可以返回多个产品，就像它可以返回一个产品一样。按照您的意愿处理响应，就像您使用其中一样：
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
int count = [response.products count];
if(count > 0){
_products = [response.products sortedArrayUsingComparator:^(id a, id b) { //sort all products by price
NSDecimalNumber *first = [(SKProduct*)a price];
NSDecimalNumber *second = [(SKProduct*)b price];
return [second compare:first];
}];
for (SKProduct *product in _products) {
NSLog(@"Product Available: %@", product.productIdentifier);
//do something with the product..
//perhaps gather the products into an array and present it somehow to the user so s/he can select what to buy?
}
}
else {
NSLog(@"No products available");
}
}
如果您想要一个可以使用的完整实现，请尝试this one

查看您创建SKProductsRequest对象的行：
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:ProductIdentifier]];
NSSet是一个袋子，里面有未分类的物品，袋子内只允许有一种（没有骰子）。
你所要做的就是改变它：
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObjects:
@"com.blahblah.unlockall",
@"com.blahblah.sounds",
@"com.blahblah.alarms",
@"com.blahblah.wallpapers",
nil]];
然后你应该有一个自定义的包装类（CustomIAPHelper），如教程。
在视图控制器中，让我们说你有一个tableView，然后代码如下：
- (void)reload {
_products = nil;
[self.tableView reloadData];
[CustomIAPHelper sharedInstance].delegate = self;
[[CustomIAPHelper sharedInstance] requestProductsWithCompletionHandler:^(BOOL success, NSArray *products) {
if (success) {
// Sort the products array (by price)
_products = [products sortedArrayUsingComparator:^(id a, id b) {
NSDecimalNumber *first = [(SKProduct*)a price];
NSDecimalNumber *second = [(SKProduct*)b price];
return [second compare:first];
}];
[self.tableView reloadData];
}
[refreshControl endRefreshing];
[activity stopAnimating];
[activity setHidden:YES];
}];
}
请记住设置和实施iAPHelper的协议方法。
