应用商店提供的独特功能可能不符合正常的跨平台购买流程。通过 Unity IAP 成功初始化时向您的应用程序提供的 IExtensionProvider
可以访问此扩展功能。
使用扩展时,无需使用依赖于平台的编译;每个扩展都带有一个假的无操作实现(在不提供扩展功能的平台上运行时会使用该实现)。
例如,以下代码段显示了 Apple 提供的 RefreshReceipt
机制(用于从 Apple 服务器获取刷新后的应用程序收据)。您可以在任何 Unity IAP 平台上编译它;如果要在非 Apple 平台(例如 Android)上运行,它将不起作用,因为绝对不会调用提供的 lambda。
/// <summary>
/// Unity IAP 准备好可以购买时被调用。
/// </summary>
public void OnInitialized (IStoreController controller, IExtensionProvider extensions)
{
extensions.GetExtension<IAppleExtensions> ().RefreshAppReceipt (result => {
if (result) {
// 成功完成刷新。
} else {
//刷新失败。
}
});
}
