Question

I am currently tinkering with SIMBL, attempting to make my own plugin. I am currently following the tutorial provided at http://www.culater.net/wiki/moin.cgi/CocoaReverseEngineering and am entirely sure that I have followed it exactly. However, when I compile and place my bundle in my SIMBL directory, I get the following error message in my logs:

3/26/12 1:52:33 PM  1:52:33 PM  SIMBL Agent[37793]  37793   -[NSCFString objectForKey:]: unrecognized selector sent to instance 0x20029e600
3/26/12 1:52:33 PM  1:52:33 PM  SIMBL Agent[37793]  37793   -[NSCFString objectForKey:]: unrecognized selector sent to instance 0x20029e600

There is currently no code in the bundle, so I am certain that this isn’t a code problem. Below is the plist for my bundle:

            <string>412</string>
        </dict>
    </array>
</dict>
</plist>

Most everything was generated by XCode 3, so I am unsure what the problem could be. Any insight would be greatly appreciated.

Edit I found this issue to be arising from another plugin, unrelated to the one I am working on.

Answer 1

The error is telling you that you have a string somewhere where there should be a dictionary.
