ios - Programmatically set image to UIImageView with Xcode 6.1/Swift

Question

I'm trying to set UIImageView programmatically in Xcode 6.1:

@IBOutlet weak var bgImage: UIImageView!

var image : UIImage = UIImage(named:"afternoon")!
bgImage = UIImageView(image: image)
bgImage.frame = CGRect(x: 0, y: 0, width: 100, height: 200)
view.addSubview(bgImage)

But Xcode is saying "expected declaration" with bgImage = UIImageView(image: image) Image "afternoon"is a PNG, and my understanding is PNG does not need an extension in XCode 6.1.

Also tried just bgImage.image = UIImage(named: "afternoon"), but still get:

UPDATE

OK, I have put the code to update UIImageView into the viewDidLoad function, but UIImageView is still not showing the image (which exists in the base directory as afternoon.png):

@IBOutlet weak var bgImage: UIImageView!
@IBOutlet weak var dateLabel: UILabel!
@IBOutlet weak var timeLabel: UILabel!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    updateTime()
    var timer = NSTimer()
    let aSelector : Selector = "updateTime"
    timer = NSTimer.scheduledTimerWithTimeInterval(0.01, target: self, selector: aSelector, userInfo: nil, repeats: true)

    var image : UIImage = UIImage(named:"afternoon")!
    bgImage = UIImageView(image: image)
}

Answer 1

Since you have your bgImage assigned and linked as an IBOutlet, there is no need to initialize it as a UIImageView... instead all you need to do is set the image property like bgImage.image = UIImage(named: "afternoon"). After running this code, the image appeared fine since it was already assigned using the outlet.

However, if it wasn't an outlet and you didn't have it already connected to a UIImageView object on a storyboard/xib file, then you could so something like the following...

class ViewController: UIViewController {
    var bgImage: UIImageView?

    override func viewDidLoad() {
        super.viewDidLoad()

        var image: UIImage = UIImage(named: "afternoon")!
        bgImage = UIImageView(image: image)
        bgImage!.frame = CGRectMake(0,0,100,200)
        self.view.addSubview(bgImage!)
    }
}
