4D for iOS: Sort criteria and action parameters enhancements

4D for iOS gives you the ability to define actions that automatically call a 4D method linked with an event on the smartphone. For example, using them, you can execute 4D code, manage and edit your app’s content using parameters, and, more recently, sort your app’s content easily using sort actions!

Defining sort criteria and action parameters has been improved to make things easier and help you work more quickly and efficiently.

LZMA: The new compression algorithm

Whenever we exchange files, we always go through the ritual of compressing the files before sending them. Since 4D v18, two commands are available, allowing you to create and read a ZIP archive using the standard zip compression algorithm.

With 4D V19 R3, the Zip Create Archive command supports a new compression algorithm: LZMA. The advantage of this algorithm is that it creates smaller archives than the standard zip compression algorithm. Let’s find out more!

4D v19 R3 Beta Starts Today

We’re pleased to announce the launch of beta testing for 4D v19 R3! One of the richest feature releases we have shipped so far!

Without further ado, let’s take a look and see what this feature release has in store for you:

 

  • Your business logic will love 4D’s new Computed Attributes in ORDA, Classes, iOS, and Android.
  • 4D for iOS with features allowing to interact with native Apple apps and build even more advanced UI’s. 
  • As for 4D for Android, we’re giving you a way to test your Android app on a real device before releasing it to users.
  • 4D Write Pro is shipped with an image setting dialog, the possibility to have different numbers of columns on the same page with continuous section breaks, and additional options to manage formula visibility. 
  • Out-of-the-box security boost with the support of the bcrypt algorithm for passwords. What’s best, there’s nothing to change in the code. Everything is automatic. 
  • More news for dark mode enthusiasts. After giving end-users a choice between dark and light mode for the appearance of their applications, it is now the turn of developers to choose between these modes during development on macOS.
  • And more (see below)!

Apply naming conventions with Form macros

by guest author Michael Höhne, 4D developer (Munich, Germany) 

 

There’s a feature in 4D v18 R5 that may have been overlooked, or at least hasn’t gotten much attention so far: Form macros. To be honest, I hadn’t spent much time on them either, until recently. In this blog post, I’ll show you a macro that saves a lot of time when applying naming conventions to list box columns, column headers, and footers. You can easily change it to fit your needs. A dedicated repo is also available on Github.

Push notification with data synchronisation

As of 4D v18 R4, you can send notifications to your application users. Now with 4D v18 R6, you can start data synchronization with a push notification.

This could be useful, for example, in the case of delivery tracking applications. First, the delivery information is updated in the database, then a notification is sent to the customer. The notification contains a request to synchronize the data, so when the customer consults the record on their smartphone, the data is up to date.
