Application tried to present a nil modal view controller in target "Current View Controller" solution

Scene reproduction

1, customize a storyboard:

Open Xcode, press Cmd+n, create a new storyboard--->next

Name the newly created storyboard: Testviewcontroller--->create

Add a label to the Testviewcontroller.storyboard whose text is: Hello-ios

2, write the UIButton uicontroleventtouchupinside event:

-(Ibaction) Btnclick: (ID) sender {    // Create load Storyboard    Uistoryboard * Storyboard = [Uistoryboard storyboardwithname:@ "testviewcontroller"  Bundle:nil];     // Associate Controller to storyboard     _viewofstoryboard = [Storyboard Instantiateinitialviewcontroller];     = [Uicolor whitecolor];    [Self Dismissviewcontrolleranimated:yes completion:nil];    [Self Presentviewcontroller:_viewofstoryboard animated:yes completion:nil];}

The following operations are run:

The following problems were encountered in loading the custom storyboard interface

Error reason: The application view presents an empty mode view controller to the target, which simply says that the view controller in storyboard is empty.

3. Solution:

• The relevant answers are given on the StackOverflow (The following is a personal translation, as indicated by the error)

Check The identifier of the Viewcontroller, if it is the same, then mentioned in storyboard.

• Check the identifier on the Viewcontroller to make sure it is unique on the storyboard.

Make sure this your buddiesorfacebook is not nil. Set a breakpoint on this line and on the debug area at the bottom see whether the object was not nil. If It is nil then problem lies in the storyboard connection.

• Make sure that your buddies or Facebook (which is not understood) is not empty. You can set breakpoints for debugging, and if the object is empty, then there is a problem with the storyboard connection.

If your current viewcontroller are not launched from storyboard then get Storyboard object like this:

If the current Viewcontroller does not start loading, you can refer to the following standard notation:

Uistoryboard *storyboard = [Uistoryboard storyboardwithname:@ "mainstoryboard"* Buddiesorfacebook = [Storyboard   instantiateviewcontrollerwithidentifier:@ "buddiesfbfriends " ] ; [Self Presentviewcontroller:buddiesorfacebook animated:yes completion:nil];

The solution above did not solve my problem, so I took a second set of solutions.

To open the Testviewcontroller.storyboard view, proceed as follows:

Check the is Initial View Controller to ensure that Viewcontroller is initialized.

Last run correctly, such as:
