A Cure For iOS App Obesity

Published June 23, 2017 by Geoff Perlman

John Gruber of Daringfireball.net recently wrote about the problem of so many iOS apps being over 100MB in size, which means they cannot be updated over a cellular connection. It really stinks to be forced to wait until you can get on WiFi just to update an app. And it can be especially bad if you really depend on the app.

Yesterday he mentioned that a big part of the problem is that apps written in Swift (and some other tools) end up bundling in a lot of standard libraries and developers don’t take the time to consider the ways in which they can trim their overweight apps down to size before shipping updates.

But you don’t have to be knowledgable about the many techniques you will need to trim your iOS apps. There is simpler solution to this problem: write your iOS apps in Xojo.

TextField: Getting the User Input

Published February 6, 2017 by Javier Menendez

Xojo is a modern, powerful programming language with an IDE that simplifies all kind of tasks related your project creation and deployment. One such helpful feature is the UI layout design; you can find it under the Library Panel, it’s a meaningful collection of graphic classes (Controls) ready to use in our apps. Probably one of the first and most used controls in apps design is the TextField, TextField simplifies the way an app can get the input from the user. Let’s see its main properties and how this control behaves when used in Desktop, Web (WebTextField) and iOS (iOSTextField) apps!

You can watch the video (in Spanish, with English subtitles) as you read and work through this post.

Localizing Web Apps: Dates & Numbers

Published January 24, 2017 by Paul Lefebvre

In desktop apps, you can use Xojo.Core.Locale to get the user’s locale for formatting dates and numbers. However, in a web app this value returns the locale used by the web server rather than the locale of the current user session.

To display dates formatted in the locale of the user session, you need to get the LanguageCode from WebSession and use that to create a locale that you can then use to display the date.

iOS Tutorial: Shorten that URL!

iOS Tutorial: Shorten that URL!

Published September 20, 2016 by Javier Menendez

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.
