I have app which i was using your premade code. When I went to build the app the I got the iOS4.1 libraries missing, most likely because I have a new install of Xcode with the iOS4.2. So that was an easy change, in a build setting. The next try to Build the app, I get: CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 4.2' I tried to find out how to solve this, and i have no clue what to do about it. The setting for the CodeSign was left unchanged. How do i go about fixing this problem? Thanks Stormen

Apps need to be signed with a valid Apple Profile before they can be installed on a device for Debug or published to the App Store for Release. They do not need to be code-signed when installing on the Simulator. When you click 'Build' or 'Build and Run', the setting in the top left drop-down box will apply. You can Build for Simulator, Device, Debug, or Release. a) Make sure you are building for Debug b) Make sure you have Simulator selected in the drop down list and not Device. To put your app on your device, choose Debug > Device AFTER selecting your Provisioning Profile in the Build Settings. You get the Provisioning Profile from Apple.

Thanks, that helps a lot with knowing where to change my option on the build and run. Thanks Stormen
