Check Internet Connectivity In Xamarin iOS

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.
Two ways to check internet connectivity 
  1. Xam.Plugin.Connectivity Plugin
  2. Reachability
Prerequisites
  • Xamarin Studio.
  • Xcode.
The steps given below are required to be followed in order to check internet connectivity in Xamarin iOS, 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

In this step, design your app, using storyboard and Toolbox. 
  1. Button(btnCreateDB)
  2. Label(lblStatus)
  3. Label(lblCheck)
 
 
Step 7

In this step, add one package in your project.
  1. Xam.Plugin.Connectivity
Go to Solution Explorer—>Package—>Add Package.

Now, choose Xam.Plugin.Connectivity and select Version. Afterwards, click Add Package.

 

Step 8

In this step, go to the ViewController.cs page. Write the code given below.

ViewController.cs  
  1. using System;  
  2. using UIKit;  
  3. using Plugin.Connectivity;  
  4. namespace XamariniOSNetworkConnection {  
  5.     public partial class ViewController: UIViewController {  
  6.         protected ViewController(IntPtr handle): base(handle) {  
  7.             // Note: this .ctor should not contain any initialization logic.  
  8.         }  
  9.         public override void ViewDidLoad() {  
  10.             base.ViewDidLoad();  
  11.             // Perform any additional setup after loading the view, typically from a nib.  
  12.         }  
  13.         partial void BtnCheck_TouchUpInside(UIButton sender) {  
  14.             // Via Xam.Plugin.Connectivity Plugin  
  15.             if (CrossConnectivity.Current.IsConnected) {  
  16.                 lblStatus.Text = "Network Available";  
  17.             } else {  
  18.                 lblStatus.Text = "Network UnAvailable";  
  19.             }  
  20.             //Via Reachability  
  21.             if (Reachability.IsHostReachable("http://google.com")) {  
  22.                 lblCheck.Text = "Available";  
  23.             } else {  
  24.                 lblCheck.Text = "Unavailable";  
  25.             }  
  26.         }  
  27.         public override void DidReceiveMemoryWarning() {  
  28.             base.DidReceiveMemoryWarning();  
  29.             // Release any cached data, images, etc that aren't in use.  
  30.         }  
  31.     }  
  32. }  


Step 9

Now, go to Run option. Choose Debug, the list of iPhone and iPad Simulators, which are available. You can choose any one Simulator and run it.
 
 

Output

After a few seconds, the app will start running on your iPhone Simulator.You will see your app working successfully. You can click Check button. 

 
 
 

Summary

This was the process of how to check an internet connectivity in Xamarin iOS, using Xamarin Studio.
