WKWebview getAllCookies在iOS 11.3中崩溃
我们最近迁移到了WKWebview。 我们添加了一个用于更改cookie的监听器，以获取更新的cookie并更新我们自己的商店。
- (void)cookiesDidChangeInCookieStore:(WKHTTPCookieStore *)cookieStore { [cookieStore getAllCookies:^(NSArray* cookies) { }]; } 加载控制器后，它会调用cookiesDidChangeInCookieStore并在“getAllCookies”崩溃。但这种崩溃只发生在TestFlight / Fabric构建中。 当我从xcode直接在设备上运行应用程序时（在调试和发布模式下）都不会发生。 以下是崩溃报告，

调用getAllCookies时看起来有溢出。这只发生在iOS 11.3中。
我能够通过在主线程中异步调用getAllCookies来修复此崩溃。
func cookiesDidChange(in cookieStore: WKHTTPCookieStore) { DispatchQueue.main.async { cookieStore.getAllCookies { (cookies) in //Code here... }) } }
