如果取消SKStoreProductViewController弹出窗口，则屏幕变为白色

To follow up on this thread targeting specific app with iOS in app purchase, all initiates well and i see the targeted app, but when I press "cancel" (as this is the only real choice in sandbox), the screen goes white and does not return to the previous screen. I have tried dismissViewController, but no luck.

要跟进这个针对iOS应用购买的特定应用程序的线程,所有启动都很好,我看到目标应用程序,但当我按“取消”(因为这是沙盒中唯一真正的选择),屏幕变白并且不回到上一个屏幕。我试过dismissViewController,但没有运气。

Any help would be appreciated.

任何帮助,将不胜感激。

OK, found it. I added the following void statement to close the VC

好的,找到了。我添加了以下void语句来关闭VC

- (void)productViewControllerDidFinish:(SKStoreProductViewController *)productVC
{
if (productVC)
{ [self dismissViewControllerAnimated:YES completion:nil]; }
}
