用户登录到我的应用程序后，我将设置窗口，设置rootViewController和makeKeyAndVisible，并且在执行此操作时会出现Thread 9: signal SIGABRT错误。 FWIW，设置-[UIWindow initWithFrame:] must be used from main thread only时，我得到紫色警告self.window = UIWindow(frame: UIScreen.main.bounds)。请参阅下面的代码以查看我的设置。
代码在此处死于该错误-AppController.swift中下面self.window!.makeKeyAndVisible()函数中的launchWindow(aWindow: UIWindow?)。

最佳答案
您应该尝试执行main thread中的代码:
func launchInWindow(aWindow: UIWindow?){
self.window = aWindow
self.initializeSDKs()
self.globalCustomization()
self.AWSUnAuthedClient.apiKey = Constants.APIKeys.AWSAPIKey
DispatchQueue.main.async {
self.window!.rootViewController = self.showLoggedInStateAndReturn(true)
self.window!.makeKeyAndVisible()
}
}
另外，在
AppDelegate.swift的这一部分中，您的问题代码库看起来有些奇怪:self.window = UIWindow(frame: UIScreen.main.bounds) //-- Purple warning here
AppController.sharedInstance.launchInWindow(aWindow: self.window)
return true
看起来这三行代码不在函数中，而是在类范围中，这很奇怪，您不应该对其进行编译。可能您粘贴的代码错误？
