If you are seeing something interesting on the iPad screen that you would want to capture. Screenshot is quite useful, especially if you have an error on your device and you want to capture an image so that later you could show it to a support tech and they could assist you in fixing the issue.
1. While you are looking at the screen press Sleep/Wake + Home button and quickly let go of the buttons.
You will see the screen quickly flashes indicating that it has taken the screenshoot. Your capture should now be placed in the Camera Roll album. To view the image go into the album and open it up.
Once you have the image you could email it.
Daniel Freeman writes; In this final MadComponents tutorial we’re going to look at the third and final Flash Builder 4.5 tutorial (from here), and do it the MadComponents way. Adobe’s Flex Test Drive for Mobile: Build a mobile application in an hour, takes you through building an AMF web service, and then building a mobile client application that connects to that service. We’re going to build the same application using MadComponents.
AMF is a binary format used to serialise ActionScript objects. A binary AMF packet is usually significantly smaller than REST XML or SOAP packet. Hence AMF services are typically much faster.
This tutorial assumes that you have some expertise in building web services, using PHP, Coldfusion, or Java. But if you’d rather do a tutorial where the web service already exists, then have a go at building a twitter client.
We recommend that you first take a look at the first six parts of this tutorial series, which will bring you up-to-speed with using MadComponents.
