In a previous blog post, we introduced the concept of Mobile Session Management. A concept that allows you to keep track of users after their initial user request. In this blog post, we’ll provide you with a component to help you easily manage your mobile users.
4D for iOS packs in several features and concepts to help you easily get started with your first mobile application. Besides the step by step tutorial, we’ll be providing blog posts tips to speed up the learning process. In this post, we’ll explore an important concept in 4D for iOS: Mobile Session Management.
We’re delighted to invite you to a preview of 4D’s upcoming new website. Let’s take a quick look and see what the new site has to offer … so far.
TestFlight is a free solution provided by Apple which allows you to send a testable version of your app to specific beta users. This way you can manage feedback from beta testers and apply any modifications (if needed) before your app is released on the App Store. In this blog post, we’ll explore how to take advantage of TestFlight for a bug-free production app.
In the first and second episodes of this trilogy, we demonstrated the basics of ORDA using list boxes, entities, and entity selections. We also showed the way to use similar list boxes with distinct data sources and how to use Meta info expression to improve the list boxes’ graphics.
Today we’re going to have even more fun, with less code!
Preemptive processes are powerful since they allow your applications to take full advantage of multi-core computers; consequently, this results in faster global execution time and more connected users. With 4D v17, we went a step further by providing you 1,000+ thread-safe commands!
Watch the Preemptive multi-threading video from the 4D Summit 2018 Keynote. It features Add Komoncharoensiri, Director of Technical Services (4D USA), explaining how the preemptive support in 4D helps you take advantage of your multi-core machines, as well as the new concepts we shipped along the way to help you boost performance and efficiency.
In code kitchens, I usually spend some time with the database settings, especially with the Compatibility settings. Often certain settings don’t follow best practices and during discussions with the application developer, I hear “oh, I never changed these” or “I’m not sure about the impact, so better not touch them”.
Since they could drastically impact the performance or behavior of your applications, we’ve begun a series of blog posts to discuss some of these “secret” settings.
In the first episode of this trilogy, we demonstrated the basics of ORDA using list boxes, entities, and entity selections. Today, we’re going a bit deeper by running some queries that will take advantage of recursive relationships. We’ll also have a quick look at how to display list boxes nicely using the “meta info expression” property.
Your iOS app is complete and you’re ready to deploy? Now it’s time for you to choose the appropriate Apple Developer Program. Apple provides various programs for you to choose from: for App Store deployment, in-house deployment, or just for testing.
Don’t panic, we’ve got you covered! If you’re still wondering which Apple Developer Program best fits your needs, then keep reading.
