Loading 3rd Party Frameworks in Xojo iOS

Published January 17, 2019 by Greg O'Lone

Did you know that it’s possible to load and use 3rd Party Frameworks in your Xojo iOS projects? There’s quite a number of good projects out there, many of which are on sites like GitHub and freely available for use in your projects. If you’re familiar with Declares in iOS, loading a 3rd Party framework requires just a couple of extra lines of code and a CopyFilesStep.

Last year at XDC 2018, Jérémie Leroy talked about making sure your screenshots mimicked the Apple method so that the date was always Jun 9th, the time was always 9:41 AM, the battery always shows as full and the WiFi strength always shows full. It got me thinking that it might be handy to be able to make the simulator always show those values when you do a debug run so that you don’t need to think about it when you are ready to start taking screenshots and movies of your app. One way to do that is to build & run project like SimulatorStatusMagic on the simulator before running your project, but it would be more useful if it was automatic.

Published January 16, 2019 by Geoff Perlman

The only built-in gesture for undo on iOS at the moment is to shake the device. This is not very intuitive to me and I’ve certainly done it by accident many times. The makers of Procreate chose a two-finger tap and have found that their users adapted to it nicely. This gesture is being adopted by more and more iOS developers. Here’s all the code you need to implement the two-finger tap for undo in your Xojo iOS apps.

Low-Code Doesn’t Mean No Control

Published December 20, 2018 by Geoff Perlman

There are low-code platforms that don’t provide ability to call directly into the operating system. Fortunately, Xojo does. Our vision for Xojo has always been to make the tool easy to learn and highly productive to develop applications, without sacrificing power when you need it.

Animating the Web: Fading Images in-out

Published December 19, 2018 by Javier Menendez

This tutorial will show you how easy it is to create animations on components of Xojo web apps, thanks to the use of the Style Editor and the WebAnimator class. Learn how to do a fade effect between two images that you can expand and adapt to your web apps.

In order to recreate this fade effect we’ll mainly use a couple of styles (WebStyle class) to set the initial status for each one of our images (instances from the WebImageView class). These will be overlaped in the web page, sharing the same position. Then we’ll add a button to the web page so it will fire the animation every time it is clicked.

What kind of variable are you?

Published December 12, 2018 by Norman Palardy

When I ask “What kind of variable are you?” I don’t mean “Are you an Integer, a String, a Variant, an Object?”. I am asking “are you a value type or a reference type?”. What’s the difference between the two?
