从 iOS 应用内消息进行购买

为了让您的用户可以直接从 iOS 应用中显示的应用内消息进行购买，您可以为 Rich Media 实现开箱即用的解决方案，并添加回调以获取有关应用内购买的更多信息。

Rich Media JavaScript 实现

要在您的 Rich Media 中实现应用内购买，请使用简单的 JavaScript 函数调用：

pushwooshImpl.makePurchaseWithIdentifier("Premium"); // product identifier specified in your App Store product information

AppDelegate 回调方法

如果您需要在购买时执行回调，请按如下方式实现 PWPurchaseDelegate 协议：

使您项目的 AppDelegate 符合 PWPurchaseDelegate 协议：

@interface AppDelegate : PWAppDelegate <PushNotificationDelegate, PWPurchaseDelegate>

在您的 AppDelegate 中实现 PWPurchaseDelegate 的方法：

#pragma mark - Purchase delegate methods
- (void) onPWInAppPurchaseHelperPaymentComplete:(NSString*) identifier {
    NSLog(@“Custom purchase delegate -- payment complete for identifier: %@“, identifier);
}
-(void)onPWInAppPurchaseHelperProducts:(NSArray<SKProduct *>* _Nullable)products {
    NSLog(@“Custom purchase delegate -- retrieved list of products”);
}
-(void)onPWInAppPurchaseHelperPaymentFailedProductIdentifier:(NSString* _Nullable)identifier error:(NSError* _Nullable)error {
    NSLog(@“Custom purchase delegate -- payment failed with identifier %@ and error %@“, identifier, error.description);
}

可用的 PWPurchaseDelegate 方法列表

产品列表

@protocol PWPurchaseDelegate <NSObject>
// Detailed information about list of products in your app
-(void)onPWInAppPurchaseHelperProducts:(NSArray<SKProduct *>* _Nullable)products;
@end

成功交易

@protocol PWPurchaseDelegate &#x3C;NSObject>
// A successfully processed transaction
<strong>-(void)onPWInAppPurchaseHelperPaymentComplete:(NSString* _Nullable)identifier;
</strong>
@end

失败交易

@protocol PWPurchaseDelegate &#x3C;NSObject>
<strong>// A failed transaction
</strong>-(void)onPWInAppPurchaseHelperPaymentFailedProductIdentifier:(NSString* _Nullable)identifier error:(NSError* _Nullable)error;
@end

从 App Store 推广

@protocol PWPurchaseDelegate <NSObject>
// An in-app purchase is initiated from the App Store, and the transaction continues in your app.
-(void)onPWInAppPurchaseHelperCallPromotedPurchase:(NSString* _Nullable)identifier;
@end

恢复已完成交易失败

@protocol PWPurchaseDelegate <NSObject>
// An error occurred while restoring transactions
-(void)onPWInAppPurchaseHelperRestoreCompletedTransactionsFailed:(NSError * _Nullable)error;
@end
