Question

Hey guys I’m using the latest version of XCode (3.2.2) and I’ve linked the framework using the tutorial. I was building my app and tested it and I get a BWToolkit exception on decoding.

I’ve included the Framework in the frameworks and added it to the copy files stage.

I even created a new dummy app including the framework and adding it to the copy files stage and it still crashes when I try to run.

Any ideas? Do I need to include it somewhere in the app? I’m worried I’ve overlooked something really simple.

)
terminate called after throwing an instance of 'NSException'

That’s the crash report

Answer 1

Okay I figured out the solution, or at least got it to a point where it works under the latest Xcode, I copy the framework on target and I also link the project against the framework and it loads.

So I add it to both: “Copy Files” and “Link Binary with Library”
