Question

I am working on the ZBarReader and getting an error

Unknown class ZBarReaderView in Interface Builder file

[UIView setReaderDelegate:]: unrecognized selector sent to instance
0x6859f20

Please look at an attached image at here or below so that you can picture what I am doing so far :-

In the storyboard, I do have a view and its custom class is ZBarReadView. I also wire it with IBOutlet in header file. In m file, I do

viewReader.readerDelegate = self;

and the error is shown after right after that.

Can anybody please point out what I have screwed up….

Answer 1

I found the solution in a thread over here

You need to add the following code in your applicationDidLaunch in your AppDelegate:

// force view class to load so it may be referenced directly from NIB
[ZBarReaderView class];

Should be running fine after that.
