Hello, In Xcode I am getting and error: /BT_Core/BT_imageTools.m:37:22: Unused function 'radians' Screen shot: http://puu.sh/7DZaB.png Any ideas?

This is a line in your code where you introduce this term. I would do a search on the term 'radians' to find where it is and determine if you need that line of the code. Hope that helps. Thanks. David

I find it in the Xcode, but I never actually introduced the term, just downloaded a project from bt and opened it in Xcode. As far as I know I never used any settings to call for radians Strange

It is in BT_imageTools.m line 37 As was pointed out to me on some other items- it is just a "warning" not an error ;) I don't think it is "currently" referenced by any BT code, but the experts would need to weigh-in on that...

Thanks for that. So such warnings will not prevent my app from being approved by the Apple reviewers?

I'd be interested if anyone else has found this - I just installed and upgraded Xcode to 5.1 (I really, really broke something earlier, deep in my Library folder. Oops.) and it was the second error/warning that appeared. Something in 5.1 just doesn't like this line of BT code. At least it's just a warning. Tubaad, let us know if it does affect your app approval. Cheers Paddy

I will let you know. So far I have just bravely deleted the line with the radians reference and hope for the best.

I have also deleted the line when it came up in my app. I have experienced no issues. Thanks. David

Hey all, I also experienced this, but my issue is now the app won't install in the simulator. I'm thinking these two things are not related, though, because the same thing happens when I delete the line. I also upgraded Xcode recently. Thoughts? I'm off to figure out why the sim won't install it now. =)

Normally when I can't run in simulator it is because of red error messages. Like missing plugins etc etc Do you have any such errors?

Me too, but no red errors right now. I've brought in plugins, files, etc., and the build succeeds, just gives me the warning triangle that the app could not be installed in the simulator...

It is a risk that the blind is leading the blind here :=), but I've had that problem, and rather that looking for the solution I simply downloaded the entire code from BT again. If you haven't made many manual changes to the code that might be fastest.

Cool, thanks, I will try that

I see this error too...perhaps the function is only used by certain plug-ins? That would mean if you downloaded all plug-ins (even ones that you don't actually use), this error might go away...even if that's the case, it's a lot of extra code in your project for an error that doesn't affect the actual building and running of your app. As I understand it, Xcode is just doing you a favor by saying, "Hey you wrote this function, but you're not actually using it anywhere, and that's wasteful, so you should use it somewhere, or get rid of it." This is probably why deleting the code or commenting it out makes Xcode happier. Instead of deleting, I often comment the code out (put two forward slashes in front)...this way, if in the future you update your app and then it complains that this function is missing, you just have to un-comment it (remove the slashes).
