LazyHackintoshGenerator.ViewController does not respond to -getFile:

回答1:

Likely a control's action in your storyboard is linked to a method getfile that no longer exists

回答2:

1. Select your ViewController.
2. Right-click on its “View Controller” icon (the blue circle with a white square inside).
3. Look for warning icons (yellow triangles).
4. Hover over them. An explanation of the problem will appear. As Feldur said, the problem is probably a leftover link from your storyboard to a method that does not exist anymore (maybe you renamed it or deleted it manually). Remove the link by clicking on the cross, and, if needed, re-link to the appropriate method in your code.

Here is an example of what it will look like in Interface Builder.
