Answer 1

You can create the same effect as used by Apple's iWorks apps for the license > section of the settings, without using any custom preference controller. Note this works for iOS 5 on the iPad, I have not tried it elsewhere. Use a PSChildPaneSpecifier for the initial control in the root plist. This points to the name of another plist file which will be the displayed child pane. You do not add .plist to the name within the root.plist file, it is implied. This plist file must be within the settings bundle. Next, use PSGroupSpecifiers in the child pane as the controls. For each paragraph use another PSGroupSpecifier - so the thing will scroll. Only use the Title section of the PSGroupSpecifier. The next gotcha that I found, was that by putting the strings in the plist file, the text was clipped in portrait orientation, so a placeholder string needs to go in the plist file and a StringTable used to point to a strings file. Text read from the strings file is properly kerned and displays without clipping.

The iPhone's "Legal" page is a custom preference controller which you can't use (not even with undocumented methods – you need to write a preference bundle in system locations which AppStore apps can't reach at all).

If you'd like to display the license, show it in the app.

I think you are going to need to use something like a UITextView, just make it non-editable. You can make in unobtrusive in your app but I think that is the only way to have 4-5 pages.

I don't think there is a nice way of displaying this in the preferences bundle. Personally I would either provide a series of url links or bring the preferences into the app itself. There is a good framework on github here that you may be able to modify.
