Adding background to ios app in xcode 6 using Swift
提问by user3411711
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?
我是ios开发的新手，所以请原谅我。我正在一步一步地进行，我想知道如何制作我想作为视图控制器背景的图像，以便我可以在它上面添加？

If you want to do it programmatically using swift here is the code:
如果您想使用 swift 以编程方式执行此操作，则代码如下：
self.view.backgroundColor = UIColor(patternImage: UIImage(named: "yourImage.png"))
Or you can create a uiimage and place your image in it:
或者您可以创建一个 uiimage 并将您的图像放入其中：
let yourImage = UIImage(named: "yourImage.png")
let imageview = UIImageView(image: yourImage)
self.view.addSubview(imageview)

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.
将 UIImageView 添加到您的视图控制器的视图中。将您的背景图像分配给图像视图。您可以在故事板文件中完成所有这些操作。
Good luck!
祝你好运！

I prefer to adding a UIImageView and setting it as background.
我更喜欢添加 UIImageView 并将其设置为背景。
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.
因为我发现下面的代码使图像有点模糊。
override func viewDidLoad() {
self.view.backgroundColor = UIColor(patternImage: UIImage(named: "yourImage.png"))
}
