我正在快速制作应用程序,但我遇到了一些问题。我正在尝试运行我的应用程序,但每次都会出错。
这是完整的错误: ***由于未捕获的异常终止应用程序' NSUnknownKeyException',原因:' [valueForUndefinedKey:]:此类不是键值currentUnityController的键值编码兼容。'
在AppDelegate中,我使用这样的服务:
@UIApplicationMain
final class AppDelegate: AppwiseCore.AppDelegate<Config> {
override var services: [ApplicationService] {
return [
UnityApplicationService(),
FabricApplicationService(),
KeyboardManagerApplicationService()
]
}
}
然后我像这样调用UnityAppcontroller:
var window: UIWindow?
var application: UIApplication?
@objc var currentUnityController: UnityAppController!
var isUnityRunning = false
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
self.application = application
unity_init(CommandLine.argc, CommandLine.unsafeArgv)
currentUnityController = UnityAppController()
currentUnityController.application(application, didFinishLaunchingWithOptions: launchOptions)
startUnity()
return true
}
最后这就是我访问app控制器的方式。
NS_INLINE UnityAppController* GetAppController()
{
NSObject<UIApplicationDelegate>* delegate = [UIApplication sharedApplication].delegate;
UnityAppController* currentUnityController = (UnityAppController*)[delegate valueForKey: @"currentUnityController"];
return currentUnityController;
}
Anny帮助?

如果您的nib(xib文件)中有一个控件链接到视图控制器中的属性(IBOutlet)或方法(IBAction),并且您已删除或重命名了该属性或方法,则运行时可以&# 39;找不到它,因为它已被重命名,因此崩溃。
