In this article, you will learn how to Change Background Colors Dynamically in Xamarin iOS App, using Xamarin Studio.
Introduction
Xamarin is a platform to develop cross-platform and multi-platform apps (for example, Windows Phone, Android, iOS). In Xamarin platform, the code sharing concept is used. In Xamarin Studio, Visual Studio is also available.
Prerequisites
The steps given below are required to be followed in order to Change Background Colors Dynamically in Xamarin iOS App, using Xamarin Studio.
Step 1
Go To Xamarin Studio.
Click New Solution—> select iOS—>select App--> Choose single View App. Afterwards, click Next.
Step 2
In this step, configure your app. Give the app name (Ex: sample), Organization Identifier. Afterwards, click Next.
Step 3
In this step, give your project name (Ex: Sample) and solution name (Ex: Sample). Give the path of your project. Afterwards, click Create.
Step 4
Subsequently, go to the solution. In the solution, get all the files and sources in your project. Now, select Main.storyboard and double-click to open Main.storyboard page.
Step 5
After opening the Main.storyboard, you can design this page, as per your desire.
Step 6
