How to set an image as background directly on a view without using imageview?

Question

 UIColor *background = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"background.jpg"]];
    _mainView.backgroundColor = background;

When i run this code, i am getting image as background on the view but like several patterns. I want to set image to my view without using ImageView. Is it possible to do via stroyboard?

Answer 1

you may use CaLayer object, assign your image as content of view's layer. other items can be added as view's subviews as before.

class CustomViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // assign image as content of view's layer
        view.layer.contents = UIImage(named: "yourImageName")!.cgImage
    }   
}
