Do I need to uninstall and reinstall xcode once I have gotten my certificates?

Oh my god!!! Getting Xcode to work is turning out to be one of the most challenging things of my life so far!

Please answer this one question:

I downloaded the SDK before getting my certificate and I have created some practice apps following along with the iTunes University. I thought you could do all this without a certificate, but I went to compile the examples and got the "no proper keychain" warning. OK cool no problem. I got the certificates now and have installed them开发者_如何学Go on my computer. But I now get a "no proper provisioning profile" error.

So my question: Do I need to reinstall xcode and rebuild these practice apps, or is there some easy thing I'm missing?

I don't think you need to reinstall Xcode, it would be ridiculous if you had to do that.

I don't have much experience with code signing, here are some things you can easily check:

Did you select the correct code signing profile in your project build settings? Project > Edit project settings > Build > search for 'code sign'. Check 'Code Signing Identity'.

If you're trying to debug on a device, check the provisioning profiles for the device in Window > Organiser
