iOS Programming 101: How To Hide Tab Bar in Navigation Interface

Hide Tab Bar in Navigation Interface

As a fresh start of the series, we’ll show you how to hide the tab bar in a navigation-based app. Several weeks ago, we developed the tab bar app. In that tutorial, we embed the navigation controller inside the tab bar controller. So when user taps on any of the recipes, the navigation controller pushes to the detail view.

Some said the tab bar takes up considerable screen estate when displaying the detail view. How can we hide it to free up more space for better reading?
If you’ve read the official API reference of UIViewController, you know the tab bar can be hidden using a line of code. There is a property named “hidesBottomBarWhenPushed” in UIViewController. It’s a Boolean value indicating whether the toolbar at the bottom of the screen is hidden. When it’s set to YES, the tab bar will be hidden when the view controller is pushed on to a navigation controller.
In our code of the Tab Bar app, we can simply add a line of code in “prepareForSegue:” method and set the “hidesBottomBarWhenPushed” properties of the RecipeDetailViewController to “YES”.
Save the change and run the app. The tab bar should be hidden when the detail view is displayed.

16 AWS Gotchas

16 AWS Gotchas In January I launched the MVP for my own startup,  Proximistyle , which helps you find what you’re looking for nearby. On advice from friends and industry contacts I chose AWS as my cloud provider. Having never had to set up my own cloud infrastructure before, the learning curve to get from no experience to a stable VPC system I was happy with was significantly steeper than expected, and had its fair share of surprises. #1 Take advantage of the free resources offered AWS offers a free tier for new accounts. If you have recently bought a domain and set up a company you qualify for the free tier for a year. Additionally, if you are a bootstrapped startup you can apply for  the Startup Builders package  and get $1000 in AWS credits. After doing the above, you’re now ready to get started with setting up the AWS infrastructure for your startup. #2 Set up billing budgets and alerting The very first thing you should do after setting up billing, is enabling a budge...

Ultimate Folder Structure For Your React Native Project

  Ultimate Folder Structure For Your React Native Project React native project structure React Native is a flexible framework, giving developers the freedom to choose their code structure. However, this can be a double-edged sword for beginners. Though it offers ease of coding, it can soon become challenging to manage as your project expands. Thus, a structured folder system can be beneficial in many ways like better organization, simplified module management, adhering to coding practices, and giving a professional touch to your project. This write-up discusses a version of a folder arrangement that I employ in my React Native projects. This structure is based on best practices and can be modified to suit the specific needs of your project. Before we get into the project structure let’s give credit to @sanjay who has the original idea of the structure but I modify his version of the code, to make it better. Base library axios  — For network calling. react-navigation ...
