Provisioned iPhone not showing in Xcode Organizer (or iTunes)

I've recently set up an app id and provisioning profile and was able to test my app on the device successfully. I then downloaded some sample iOS 开发者_Python百科XCode projects and upon deploying one of them and deleting the sample app from the phone have since been unable to sync the phone with iTunes or see it as connected in the Xcode organizer window (the device is still listed in the lefthand pane, but shows up as disconnected). All new projects created in Xcode are now greeted with the following message when I attempt to build and run on the device.

No provisioned iOS device is connected.

I'm running Xcode 3.2.5 and iOS 4.2.

Any ideas?

Many thanks.

Typically when I run across this issue I will

1. Disconnect the device
2. Clean the projects
3. Delete the device from the Organizer
4. Restart Xcode
5. Reconnect the device

Then the majority of the time the device will be recognized again. I do find it strange that even iTunes can't recognize it though. Maybe try restarting the device even?

I had the same problem and posted about it over at Apple.SE. Reinstalling iTunes fixed it for me.

On Xcode 5.1.1

Unplug device, remove device from Window->Organizer, Product->Clean, close Xcode, plug in device, start Xcode - Window->Organizer and add to Member Center

Hope this helps. The issue occurred for me when I enabled iCloud and there was a sync issue on iTunes.
