For information about the functions you use to create PDF content, see UIKit Function Reference. The following sections describe the PDF creation process in more detail using a simple example. Use UIKit or Core Graphics routines to draw the content of the page.Īdd links if needed (as described in Creating Links Within Your PDF Content).Įnd the PDF context (as described in Creating and Configuring the PDF Context) to pop the context from the graphics stack and, depending on how the context was created, either write the resulting data to the specified PDF file or store it into the specified NSMutableData object. It consists of the following steps:Ĭreate a PDF context and push it onto the graphics stack (as described in Creating and Configuring the PDF Context).Ĭreate a page (as described in Drawing PDF Pages).
The overall drawing process is similar to the process for creating any other image (described in Drawing and Creating Images). When you are done, what you are left with is a PDF version of what you drew. You can then create one or more PDF pages and draw into those pages using the same UIKit and Core Graphics drawing routines you use when drawing to the screen. These functions let you create a graphics context that targets a PDF file or PDF data object. The UIKit framework provides a set of functions for generating PDF content using native drawing code.
