How to Change Uibutton Image in Swift

How to change UIButton image in Swift

From your Obc-C code I think you want to set an Image for button so try this way:

let playButton  = UIButton(type: .Custom)
if let image = UIImage(named: "play.png") {
    playButton.setImage(image, forState: .Normal)
}

In Short:

playButton.setImage(UIImage(named: "play.png"), forState: UIControlState.Normal)

For Swift 3:

let playButton  = UIButton(type: .custom)
playButton.setImage(UIImage(named: "play.png"), for: .normal)

Swift set button image

From Apple documentation:

A control becomes highlighted when a touch event enters the control’s
bounds...

Highlighted state of a control

button.setImage(UIImage(named: "button_normal_state"), for: .normal)
button.setImage(UIImage(named: "button_pressed_state"), for: .highlighted)

How to change button image in swift?

You don't need ".png".

If ".imageWithRenderingMode(.AlwaysOriginal)" is working for you: To keep the same image in different states, you have to set the same image/properties for the different states.

@IBOutlet var tapButton: UIButton!

override func viewDidLoad() {
    super.viewDidLoad()

    tapButton.setImage(UIImage(named: "redTap")?.imageWithRenderingMode(.AlwaysOriginal), forState: .Normal)
    tapButton.setImage(UIImage(named: "redTap")?.imageWithRenderingMode(.AlwaysOriginal), forState: .Highlighted)
}

How to change UIButton's image every time it is pressed

Thanks for mentions of setBackgroundImage to Xavier L. from the other answer.
Try the following code:

import UIKit
class ViewController: UIViewController {

    @IBOutlet var button: UIButton!
    var buttonActive = false

    override func viewDidLoad() {
        super.viewDidLoad()
        button.setBackgroundImage(UIImage(named: "apple"), for: .normal)
    }

    @IBAction func buttonPressed() {
        if buttonActive {
            button.setBackgroundImage(UIImage(named: "apple"), for: .normal)
        } else {
            button.setBackgroundImage(UIImage(named: "pineapple"), for: .normal)
        }
        buttonActive = !buttonActive
    }
}

And your storyboard should look like that:

N.B. On Stack Overflow you should perform some actions before asking. Try to include some code you tried.

Xcode: change UIButton image positioning

In storyboard change the title as 'attributed type. Then you can change the font, color, image, its alignment and event the gap between title and image.

i want to change UIButton and UIImage view by clicking on a button. But images for UIButton and Image view are different

I hope I got your question correct. You have a button with an image on it and an imageview. 2 separate things. And you want to change your images.

If you want to change your buttons image by clicking on it you should not only have IBAction but also IBOutlet for that button. Control drag and make an outlet for it. In the button's IBAction function just change your button's image to what you want, as well as your image view's.

Can't change UIbutton image for different state

This helped me (swift 3.0)

btn.setImage(UIImage(named:"yourFriend")?.withRenderingMode(.alwaysOriginal), for: .normal)

btn.setImage(UIImage(named:"yourFriend")?.withRenderingMode(.alwaysOriginal), for: .disabled)

Change a UIButton's image that was created programmatically within a for loop Swift

This is suspect:

 @objc func tap(sender: UIButton) {
     DispatchQueue.main.asnyc{
     buttonArray[sender.tag].setImage(UIImage(named:"Somename"))
 }

You are already on the main queue, and the sender is the button that was tapped. So you don't need the array.

@objc func tap(sender: UIButton) {
     sender.setImage(UIImage(named:"Somename"))
}
