Questions tagged [uiprintformatter]

UIPrintFormatter is an abstract base class for print formatters: objects that lay out custom printable content that can cross page boundaries. Given a print formatter, the printing system can automate the printing of the type of content associated with the print formatter.

Examples of such content could be a web view, a mix of images and text, or a long text document. The UIKit framework provides several concrete subclasses of UIPrintFormatter: UISimpleTextPrintFormatter, UIMarkupTextPrintFormatter, and UIViewPrintFormatter.

You can assign a single print formatter for a print job via the printFormatter property of the UIPrintInteractionController shared instance; or you can specify one or more print formatters that are associated with specific pages of a page renderer through the addPrintFormatter:startingAtPageAtIndex:method of UIPrintPageRenderer. A page renderer is an instance of a custom subclass of UIPrintPageRenderer that draws content for printing.

UIPrintFormatter publishes an interface that allows you to specify the starting page for a print job and the margins around the printed content; given that information plus the content, a print formatter computes the number of pages for the print job.
