使用Swift在xcode 6中为ios app添加背景

Question

I am new to ios development so please forgive me. I am taking it step by step and I was wondering how would I make a image I want to be the background in the view controller so I can add on top of it?

Answer 1

If you want to do it programmatically using swift here is the code:

 self.view.backgroundColor = UIColor(patternImage: UIImage(named: "yourImage.png"))

Or you can create a uiimage and place your image in it:

let yourImage = UIImage(named: "yourImage.png")
let imageview = UIImageView(image: yourImage)
self.view.addSubview(imageview)

Answer 2

Add a UIImageView to your view controller's view. Assign your background image to the image view. You can do all this in the storyboard file.

Good luck!

Answer 3

I prefer to adding a UIImageView and setting it as background.

override func viewDidLoad() {
    let backgroundImage = UIImageView(frame: UIScreen.mainScreen().bounds)
    backgroundImage.image = UIImage(named: "bg_image")
    self.view.insertSubview(backgroundImage, atIndex: 0)
}

Because I found the following code make the image a little blurry.

override func viewDidLoad() {
    self.view.backgroundColor = UIColor(patternImage: UIImage(named: "yourImage.png"))
}
