'Storyboard doesn't contain a view controller with identifier' only on Device

问题

I have this storyboard :

With this ViewController :

I have this code to instanciate my VC :

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

When i'm running on simulator, everything works thine.

But when i launch on real device, i have this exception :

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''

libc++abi.dylib: terminating with uncaught exception of type NSException

EDIT :

I have my storyboard correctly loaded :

    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")

回答1:

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

EDIT

Just CLEAN your project (CMD+SHIFT+K) as you have change the storyboard name I think.

回答2:

Close your project and open it again. If you noticed the identifier is gone, then it must be a problem of auto-saving. Simply save your storyboard file after putting your new identifier. and Clean-Build-Run.

回答3:

Try to change it to :

let VC = self.storyboard!.instantiateViewControllerWithIdentifier("POIListViewController") as! POIListViewController

回答4:

I had a similar problem (except it wasn't only on device).

None of the previous suggestions in this thread worked for me. What worked was going to the Identity Inspector (in right hand Utilities Pane), and making sure the Storyboard ID field was also populated with the View Controller name (same name as the Class field above it).

回答5:

I had such a problem because of a copy of the localization file. Perhaps the simulator includes English, but this gadget has its own language. See if you have a storyboard with two localization files?
