I'm trying to create a UIImage View programmatically, I have a new view and I tried doing this
let imageName = "yourImage.png"
yourview.backgroundColor = UIColor.colorWithPatternImage(UIImage(named:imageName))
this did not work because I don't know what this should be yourview in the second line.
Question: How do I make a UIImageView appear on the screen by coding it instead of doing it in the storyboard
This question is related to
ios
xcode
swift
uiimageview
uiimage
Thanks, MEnnabah, just to add to your code where you are missing the =
sign in the declaration statement:
let someImageView: UIImageView = {
let theImageView = UIImageView()
theImageView.image = UIImage(named: "yourImage.png")
theImageView.translatesAutoresizingMaskIntoConstraints = false //You need to call this property so the image is added to your view
return theImageView
}()
Everything else is, all perfect for Swift 3.
First create UIImageView then add image in UIImageView .
var imageView : UIImageView
imageView = UIImageView(frame:CGRectMake(10, 50, 100, 300));
imageView.image = UIImage(named:"image.jpg")
self.view.addSubview(imageView)
You can use above in one line.
let imageView = UIImageView(image: UIImage(named: "yourImage.png")!)
Swift 4:
First create an outlet for your UIImageView
@IBOutlet var infoImage: UIImageView!
Then use the image property in UIImageView
infoImage.image = UIImage(named: "icons8-info-white")
This answer is update to Swift 3.
This is how you can add an image view programmatically where you can control the constraints.
Class ViewController: UIViewController {
let someImageView: UIImageView = {
let theImageView = UIImageView()
theImageView.image = UIImage(named: "yourImage.png")
theImageView.translatesAutoresizingMaskIntoConstraints = false //You need to call this property so the image is added to your view
return theImageView
}()
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(someImageView) //This add it the view controller without constraints
someImageViewConstraints() //This function is outside the viewDidLoad function that controls the constraints
}
// do not forget the `.isActive = true` after every constraint
func someImageViewConstraints() {
someImageView.widthAnchor.constraint(equalToConstant: 180).isActive = true
someImageView.heightAnchor.constraint(equalToConstant: 180).isActive = true
someImageView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
someImageView.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: 28).isActive = true
}
}
Make sure to put:
imageView.translatesAutoresizingMaskIntoConstraints = false
Your image view will not show if you don't put that, don't ask me why.
In Swift 4.2 and Xcode 10.1
//Create image view simply like this.
let imgView = UIImageView()
imgView.frame = CGRect(x: 200, y: 200, width: 200, height: 200)
imgView.image = UIImage(named: "yourimagename")//Assign image to ImageView
imgView.imgViewCorners()
view.addSubview(imgView)//Add image to our view
//Add image view properties like this(This is one of the way to add properties).
extension UIImageView {
//If you want only round corners
func imgViewCorners() {
layer.cornerRadius = 10
layer.borderWidth = 1.0
layer.masksToBounds = true
}
}
In Swift 3.0 :
var imageView : UIImageView
imageView = UIImageView(frame:CGRect(x:10, y:50, width:100, height:300));
imageView.image = UIImage(named:"Test.jpeg")
self.view.addSubview(imageView)
