How to link an installed app in iBooks Author

Yes. Actually, what iBooks Author excels at is letting you format your text precisely, with elaborate styles and style sheets, and preventing the user from changing the font, point size, or theme. You get tremendously precise formatting and layout, and the user can't change anything at all in landscape orientation, while they can scale font size a bit in portrait orientation.

Here's the main drawback that I have just discovered myself: iBooks Author will only output books that can be read on an iPad with iOS 5 running the new iBooks 2.0. The book you create with iBooks Author cannot be read on an iPhone or iPod Touch or anything running iOS 4.2.1 or iBooks 1.0.

Secondly, the file size of a book that is all text (no illustrations) is HUGE. I'm talking 20 times as large as it should be. I've tested it. A book that was 900K in size created with other tools becomes 20MB in size when created in iBooks Author.

There is a way more simple way to do this... I'm using iBooks Author 2.0 it has a "Paste and Retain Styles" option that works like a charm.

I edit the code snippets in Xcode then select and copy the section I want:

Then control click where I want to paste it into my book:

Done! The snippet is included with syntax highlighting:

Pro Tip 1: Take time to set up Xcode to use the font you want so you don't have to fiddle with it once the code is pasted into iBooks Author:

Pro Tip 2: Here are some other useful settings for your code snippet paragraphs, keep the lines together and disable auto-hyphenation.
