UIView背景图片未显示

Question

I've defined a bg image in the Xcode Images.xcassets and want to use it as background for a view but the bg stays black. I'm using:

override func viewDidLoad()
{
    super.viewDidLoad();
    view.backgroundColor = UIColor(patternImage: UIImage(named: "background_ipad"));
}

this should work according to some other tickets on SO but for some reason the background stays black, not showing the image. Any ideas why this would happen?

Answer 1

Use this code:

SWIFT

view.layer.contents = UIImage(named:"Image_Name").CGImage

Objective-C

view.layer.contents = (__bridge id _Nullable)([UIImage imageNamed:@"Image_Name"].CGImage);

Answer 2

Click on the catalog image

and ensure target membership

Answer 3

For objective C

self.view.layer.contents = (__bridge id _Nullable)([UIImage imageNamed:@"Image_Name"].CGImage);

For Swift

self.view.layer.contents = UIImage(named:"Image_Name")!.CGImage
