    I did the same thing, added files for "MyViewController", then removed them, then added them again in a different place in the project. Then once I got to the point where I was supposed to add the actions, it gave me this error.


    I was able to get it to work properly after I went into both MyViewController.h and MyViewController.m and slightly modified and saved those files. I just added a couple lines of whitespace in both the @interface/@end and @implementation/@end blocks, and then tried to set up the action connection again, and it magically worked.

    This worked for me too

    Quitting XCode solved it for me too.

    In fact when I quit, XCode had a crash bug and did not exit cleanly.

    It restarted with all my code intact and I was able to drag and create the new Action as advertised.

    Restarting Xcode worked for me as well thankfully.


    Odd though, imagine this happened while coding a project of your own where you don't have instructions that tell you what should happen next.  I wouldn't immediately be blaming the software, I'd just assume I'd missed something when really it was the compiler's fault.


    A good lesson that I'll be keeping in mind for future projects.

    just experienced this problem in Xcode 4.1.  restarted and the problem is gone and I was able to CTRL-click drag and Xcode created the code in my .h file:



    {code}- (IBAction)viewButton1:(id)sender;{code}

    I just got this problem after creating a new file with the same name as a previously deleted file. Fixed it by changing the header and implementation files (just by adding a space at the end of a line), and then saving them.

    I had the same problem and just solved it that way:

    for some reason the mainController file, that caused the problem had a localization (in the right menu) - in the english folder.

    I just deleted it by pressing the minus sign and it worked.

    just make sure you have a copy of the file in the main folder (that holds the english folder too).

    Just select 'File's owner" and in "Identity inspector" set the right Controller class instead of NSObject.

    Reindexing the project was the only thing that helped in my case. Here's how to do it:

    Command + S saved me

    Re-indexing the project (as Bidli) references was the only thing that worked for me.
