Here we will learn iOS ui image view in swift with example and how to use iOS image view to show images in swift application using Xcode editor.

iOS UI Image View

In iOS image view is used to show the images in iOS application and it will resize the images automatically to make fit with the current size of view. 

 

By using iOS image view we can show single image or animated sequence of images with transparent or opaque background based on our requirement. If we use iOS image view to show image in application that will be like as shown below

 

iOS Image View Sample Example

 

We can use Image View in our iOS applications by adding UIImageView class reference.

 

Now we will see how to use iOS UI image view in our iOS applications with example.

Create iOS Image View App in Swift

To create new project in iOS Xcode open Xcode from /Applications folder directory. Once we open Xcode the welcome window will open like as shown below. In welcome window click on the second option “Create a new Xcode Project” or choose File --> New --> Project

 

Xcode application to create ios project

 

After selecting “Create a new Xcode project” a new window will open in that we need to choose template.

 

The new Xcode window will contain several built-in app templates to implement common type of iOS apps like page based apps, tab-based apps, games, table-view apps, etc. These templates are having pre-configured interface and source code files. 

 

For this iOS image view example, we will use most basic template “Single View Application”. To select this one, Go to the iOS section in left side --> select Application --> In main area of dialog select “Single View Application” and then click on next button like as shown below.

After click Next we will get window like as shown below, in this we need to mention project name and other details for our application.

 

Product Name: “Image View in iOS”

 

The name whatever we enter in Product Name section will be used for the project and app.

 

Organization Name: “Tutlane”

 

You can enter the name of your organization or your own name or you can leave it as blank.

 

Organization Identifier: “com.developersociety”

 

Enter your organization identifier in case if you don't have any organization identifier enter com.example.

 

Bundle Identifier: This value will generate automatically based on the values we entered in Product Name and Organization Identifier.

 

Language: “Swift”

 

Select language type as “Swift” because we are going to develop applications using swift.

 

Devices: “Universal”

 

Choose Devices options as Universal it means that one application is for all apple devices in case if you have any specific requirement to run app only for iPad then you can choose the iPad option to make your application restricted to run only on iPad devices.

 

Use Core Data: Unselected

 

This option is used for database operations. In case if you have any database related operations in your application select this option otherwise unselect the option.

 

Include Unit Tests: Unselected

 

In case if you need unit tests for your application then select this option otherwise unselect it.

 

Include UI Tests: Unselected

 

In case if you need UI tests for your application then select this option otherwise unselect it.

 

Once you finished entering all the options then click on Next button like as shown below.

Once we click on Next button new dialog will open in that we need to select the location to save our project. Once you select the location to save project then click on Create button like as shown below

After click on Create button the Xcode will create and open a new project. In our project Main.storyboard and ViewController.swift are the main files which we used to design app user interface and to maintain source code. 

 

Main.storyboard - Its visual interface editor and we will use this file to design our app user interface 

 

ViewController.swift - It contains source code of our application and we use this file to write any code related to our app.

 

Now in project select Main.storyboard file the Xcode will open visual interface editor like as shown below.

Add iOS UI Controls to the View in Swift

Now we will add controls to our application for that open Object Library. The Object Library will appear at the bottom of Xcode in right side. In case if you don't find Object library, click on the button which is at the third position from the left in the library selector bar like as shown below. (Alternatively you can choose View --> Utilities --> Show Object Library.)

As we discussed our user interface will be in Main.storyboard file so open Main.storyboard file. Now in Object library search for the Image View in Filter field then drag and drop the Image View into Main.storyboard ViewController and set image like as shown below.
