非主线程上的 SKStoreProductViewController 初始化 [英] SKStoreProductViewController initialization on non main thread

问题描述

我在非主线程上初始化 SKStoreProductViewController 时偶尔会出现崩溃.我没有看到任何关于在主线程上初始化它的文档.SKStoreProductViewController 需要在主线程初始化吗?

I am seeing an occasional crash as I initialize SKStoreProductViewController on non main thread. I don't see any docs about initializing it on main thread. Do we have to initialize SKStoreProductViewController on main thread?

推荐答案

我只是把这个作为一个答案，以便它可以突出 rmaddy 在评论中提出的观点.

I just made this as an answer so that it can highlight the point made by rmaddy in the comment.

重要

仅在应用的主线程或主调度中使用 UIKit 类队列，除非另有说明.这个限制特别适用于派生自 UIResponder 或涉及的类以任何方式操纵应用的用户界面.

Use UIKit classes only from your app’s main thread or main dispatch queue, unless otherwise indicated. This restriction particularly applies to classes derived from UIResponder or that involve manipulating your app’s user interface in any way.

正如 rmaddy 指出的，类定义:

And as rmaddy pointed out, the class definition:

open class SKStoreProductViewController : UIViewController

所以是的，你需要使用主线程.

So yes, you need to use the main thread.
