Expected Behavior The modal view controller should be presented without crashing.

Actual Behavior The app crashes with an NSInvalidArgumentException when trying to present a nil modal view controller.

Additional Information Please investigate this issue and provide any possible fixes or workarounds. Thank you!

MTGInnerStoreProductViewController is just a subclass of system's SKStoreProductViewController, it won't present any nil controller, maybe you can check:

  1. if your own code has some logic like found the topmost view controller and MTGInnerStoreProductViewController is the topmost view controller and you use it to present another controller;
  2. look at implementation of [SafeDKAdsInterceptor swizzleViewControllers], check if this would return nil controller or not.

MTGInnerStoreProductViewController 只是系统的 SKStoreProductViewController 的一个子类，它不会显示任何零控制器，也许你可以检查一下：

  1. 如果你自己的代码有一些逻辑，比如找到最顶层的视图控制器，并且 MTGInnerStoreProductViewController 是最顶层的视图控制器，并且你使用它来呈现另一个控制器；
  2. 查看的实现[SafeDKAdsInterceptor swizzleViewControllers]，检查这是否会返回 nil 控制器。

I feel like the problem is caused by a user manually crossing out the app when watching an MTG reward/interstitial ad
