Free wifi is everywhere. It may seem like a godsend if you stumble upon a free wifi network, but watch out. A wifi network can be easily created just to steal your information.
I’m going to show just how easy it is to setup a fake free wifi network to monitor all network traffic going through it. To do this you will need two network cards, one will connect to an existing wifi network and the other will rebroadcast it out as “free wifi”. I will explore two different methods of doing this, but both have the same end result. I will use a Mac for both, but the same thing can be performed on Windows or Linux.
This post is going to outline a bunch of tips and tricks to squeeze every last piece of performance out of a UITableView.

In a project I’m currently working on I needed to generate a PDF based on a bunch of information the user had entered. The PDF needed to be very fancy and have images and graphics all over the place to make it look really nice. Instead of drawing everything from scratch I used to some of the PDF libraries on iOS that allowed me to create a new PDF based on an existing one, then draw the dynamic content over the top.
