In this Xojo tutorial we will see how simple it is to make an iOS App that shortens an entered URL using the public API of Bit.ly. We will use our own subclass inherited from Xojo.Net.HTTPSocket, and the Declare statement in order to use some functions and methods found on the native Cocoa Touch API. In fact, the use of Declare is mandatory because with the new Xojo Framewok we don’t yet have access to the EncodeURLComponent function available with the old framework. This one is a big help in substituting any ilegal character with his hexadecimal value for the final URL’s composition.

We are always keen to see apps and projects that Xojo developers have made for their Raspberry Pi 2 and Raspberry Pi 3 single-board computers. Especially since Xojo 2019r1 when building for Pi Desktop and Console is free with Xojo Pi!
I am pleased to announce some updates to our GPIO project to make it even easier to use more types of hardware in your Raspberry Pi projects.
Comments closedYou don’t need to hook up your Pi to a physical display, keyboard and mouse. You can set up VNC on the Pi so you can remotely connect to it.
My Raspberry Pi 2 sits on my desk next to one of my speakers. It’s not hooked up to any display. I use a combination of SSH, SFTP and VNC when I need to work with it.
Comments closedBjorn at Einhugur has created a bunch of tutorials for projects you can create using Xojo and a Raspberry Pi.
Comments closedIf you are creating Xojo desktop apps for your Raspberry Pi (and why not since Xojo Pi if free for desktop & console apps), you may want to take advantage of the HTMLViewer control for easy display of HTML content or apps.
Comments closedIn order to interface with the Raspberry Pi, you often want to use the General Purpose Input/Output (GPIO) port. It is easy enough to connect a broadboard to the port, but how do you write Xojo code that can talk to the port?
Comments closedSometimes you need a feature that is not available directly from the Xojo framework. Responding to this need is what Declares are designed for: to get access to system native APIs. On OS X, you typically look at the Cocoa APIs. On Windows, the Win32 APIs. Finally on Linux, the GTK APIs.
Comments closedDespite our best efforts here at Xojo, everyday can’t be #CodeDay! So we figure we better go all out for the first official, national Code Day! Saturday, May 24th, we want to help you join thousands of students in 24 cities across America celebrate technology, share ideas and build cool apps!
