IFXPDFFactory 0.1.0 Alpha version now available
November 15th, 2013
First version of IFXPDFFactory for iOS is now available. It's an alpha version which means it has bugs and only the basic features are implemented but it lets you feel the API and test the concepts shown in the articles published so far.
There are 14 samples included in the samples browser application to show the features implemented so far. There is no Apple style documentation yet, but it will come.
Feel free to download the framework and take it for a test drive. Any questions you might have can be posted here as comments or sent by email to me.

Support for the base 14 PDF fonts has been implemented. Also the text drawing methods have been implemented.
The base class for all fonts is IFXPDFBaseFont. The standard 14 PDF fonts are implemented through the IFXPDFFont class, which inherits from IFXPDFBaseFont. The supported fonts are: Helvetica, Helvetica Bold, Helvetica Italic, Helvetica Bold-Italic, Courier, Courier Bold, Courier Italic, Courier Bold-Italic, Times Roman, Times Roman Bold, Times Roman Italic, Times Roman Bold-Italic, ZapfDingbats and Symbol.
IFXPDFFactory – part 7 – PDF images
June 28th, 2013
Support for drawing images on PDF pages has been implemented. An image drawn on a PDF page is represented by the IFXPDFImage class. At this moment a PDF image can be created only from a CGImage object, later I'll add support for creating images directly from image files or memory.
PDF page imposition using CoreGraphics on iOS
June 11th, 2013
A recent question on StackOverflow asked about how to create a single large PDF page from multiple PDF pages. This process is known as page imposition, it lets you combine multiple PDF pages onto larger sheets to create books, booklets or other special arrangements.
My answer to that question handled only the situation when all the source pages had the same size and rotation. The code here is more complex and it handles any combination of page sizes and rotation.
