Create A Popup View In Xamarin iOS App

Introduction

Xamarin is a platform to develop cross-platform and multi-platform apps (for example Windows phone, Android and iOS). In Xamarin platform, the code sharing concept is used. In Xamarin Studio, Visual Studio is also available.

• Xamarin Studio.
• Xcode.

The steps given below are required to be followed in order to create a popup view in Xamarin iOS, using Xamarin Studio.

Step 1

Go to Xamarin Studio.

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

        public override void ViewDidLoad() {
            base.ViewDidLoad();
            // Perform any additional setup after loading the view, typically from a nib.
        }
        partial void BtnOk_TouchUpInside(UIButton sender) {
            viewPopup.Hidden = true;
        }
        partial void BtnPopup_TouchUpInside(UIButton sender) {
