Loaded the "blueview" nib but the view outlet was not set error solution.

Create multiple views during exercises todayProgramThe following errors always occur:

 

P. P1 {margin: 0.0px 0.0px 0.0px 28.0px; text-indent:-28.0px; Font: 11.0px Menlo}

'-[Uiviewcontroller _ loadviewfromnibnamed: Bundle:] loaded the "blueview" nib but the view outlet was not set .'

 

I only know that I have not done any association between the NIB file and the xxxviewcontroler program. I hereby record it:

 

1. Open the NIB file.

2. Click "file's owner" and press command + 4 to set the class to xxxviewcontroler.

3. Press Control + "files's owner". There is a default iboutlet variable view in it. Check whether there is any association in the future. If not, pull the following view to associate with the view.
