'故事板不包含仅在设备上具有标识符的视图控制器

Question

我有这个故事板:

使用此ViewController:

我有这个代码来实现我的VC:

let VC = UIStoryboard(name: "Main_iPhone", bundle: nil).instantiateViewControllerWithIdentifier("POIListViewController")

当我在模拟器上运行时,一切正常.

但是当我在真实设备上启动时,我有这个例外:

2016-07-12 10:56:19.073 App-Ely[1935:562264] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Storyboard (<UIStoryboard: 0x185481b0>) doesn't contain a view controller with identifier 'POIListViewController''

编辑:

我正确加载了故事板:

    let storyboard = UIStoryboard(name: "Main_iPhone", bundle: nil)
    // 'storyboardName' contains "Main_iPhone"
    let storyboardName : String = storyboard.valueForKey("name") as! String
    let VC = storyboard.instantiateViewControllerWithIdentifier("POIListViewController")

Answer 1

let storyboard = UIStoryboard(name: "Main_iPhone", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("POIListViewController") as! UIViewController

只需清理你的项目(CMD + SHIFT + K),因为你改变了我认为的故事板名称.
