无法在捆绑包中加载NIB：“使用Swift在iOS中使用NSBundle

Question

当我尝试从登录页面切换到Tabbar控制器后，我的应用程序不再运行

警告在下面。

我的第一个尝试代码如下。 “主页”是标签栏控制器的标识符

self.performSegueWithIdentifier("Home", sender: nil)

let appDelegate = UIApplication.sharedApplication().delegate! as! AppDelegate

let initialViewController = self.storyboard!.instantiateViewControllerWithIdentifier("Home") //as! UIViewController
appDelegate.window?.rootViewController = initialViewController
appDelegate.window?.makeKeyAndVisible()

我的第二个尝试代码的一部分如下：

let storyboard: UIStoryboard = UIStoryboard(name:"Main", bundle: NSBundle.mainBundle())
let tabBarController: UITabBarController = storyboard.instantiateViewControllerWithIdentifier("Home") as! UITabBarController

Answer 1

您是否在页面之间进行了搜索？ 您是否将segue identifier设置为“主页”？ 如果是这样，只留下一行代码，它将起作用

self.performSegueWithIdentifier("Home", sender: nil)

另一方面，如果确实将Tabbar控制器标识符（由于使用情节Storyboard ID ，这是Tabbar控制器的身份检查器中的Storyboard ID字段）设置为“主页”，则可以使用以下代码：

let appDelegate = UIApplication.sharedApplication().delegate! as! AppDelegate

let initialViewController = self.storyboard!.instantiateViewControllerWithIdentifier("Home") //as! UIViewController
appDelegate.window?.rootViewController = initialViewController
appDelegate.window?.makeKeyAndVisible()

您的日志告诉我您没有设置此标识符。 不要将其与segue标识符混淆，这是不同的事情，您更喜欢为它们使用不同的字符串。
