• First sign up as an Apple Developer
• Login and then go to the Provisioning Portal
• Create an app ID.  DON’T USE A WILDCARD!!!!!  Note you cannot delete these app ids unless you call Apple and ask for help at 408-974-4897
• In your Info.plist file, specify something like com.mycompany.myappname for Bundle Identifier.  It has to match what you did when you created the app id. EXCEPT DON’T put the numbers in front!  Don’t do 8NX26&9MG7.com.coolapps.waycool just put in com.coolapps.waycool
• Now create a Developer Certificate, later you can create a Distribution Certificate, but for now just create a new developer certificate.  Revoke the existing one if it’s giving you problems.
• Follow the instructions for using Key Chain Access to generate a “Certificate Signing Request”.  Once this is done, you upload it into the Distribution Certificate area.
• Go to the devices tab and add all your devices.
• Now go to Provisioning / Development and click on New Profile.  Make sure you pick the Developer Certificate the app id you just created, and then select the devices you want to have in the profile.  I just select all of them normally.
• Now download the profile and double-click on it.  This puts it in Xcode and the key chain.  But YOU ALSO NEED TO DO THIS: Refresh in the organizer.   Why?  Apple says “Xcode gets confused”
• Now go to the project and targets and pick the provisioning profile and then build to the phone.
• Now follow the same steps and make an ad-hoc distribution profile.

Do one better, disable safe sleep forever and save diskspace on your boot drive:

To disable safe sleep, run the two following commands in Terminal:
$ sudo pmset -a hibernatemode 0
$ sudo nvram “use-nvramrc?”=false

• Start a new XCode Project
• Duplicate the current Target
• Rename the Duplicated Target
• Rename the Duplicated Info.plist File
• Change the Icons in the Duplicated Info.plist file to use the Lite Version Icons
• Change the Bundle Identifier to match with the bundle identifier from Apple for the Lite Version
• Edit Build Properties of the Duplicated Target
  - Add C / C++ Compiler Flags
  - Change the Product Name
  - Change the name of the Info.plist file to the name of the Duplicated Info.plist File
• Add Logic to code to separate features of Lite and Full version.

Chris’ explanation is good, but here are a few gotchas:

• Say you are going to have two versions of a Resources, eg. MyResourcesFolder-Full and MyResourcesFolder-Lite, you want first remove references to both of these folders before duplicating the target. Then you add MyResourcesFolder-Full to only the full target and MyResourcesFolder-Lite to only the lite target.
• You only have to change the BundleIdentifier field in the copied Info.plist to be anything you want. For instance, com.yourcompany.${PRODUCT_NAME:rfc1034identifier} can be renamed to anything: eg: com.joesfishhouseonbleecker.${PRODUCT_NAME:rfc1034identifier}. When he talks about “Apple assigning the identifier” this happens in Xcode, you don’t have to go to the provisioning portal etc.
• You have to add a row when you are editing the copied Info.plist before you can specify an icon file name for the lite version. I also explicitly named the icon in my full version to avoid any confusion
• Before building each target I needed to delete the build folder manually, or else some of the wrong resources got put in each version
• You might need to delete the iPhone simulator folder in ~/Library/Application Support/iPhone Simulator before building

A shout out to Jose Solorzano who wrote the simple HTML DOM parser.

• For low light go to P mode and pick the highest ISO possible.  Go to Shooting Settings Display and then hit the ISO button, pick 6400.  Night shots start looking good.
• Also try the continuous drive mode (page 70 of the manual)
