How can i pass both x and y axis along with height and width of Screen to take screenshot programmatically in swift

Question

I added a UIImageView on an ImageView, so i want to take screenshot of these two imageviews so that they look like one, any other recommendation is also appreciated.

I made a button that helped me take a screen shot, I have added x-axis and y axis,

func takeScreenshot(_ shouldSave: Bool = true) -> UIImage {
    var screenshotImage :UIImage?
    let layer = UIApplication.shared.keyWindow!.layer
    let scale = UIScreen.main.scale
    UIGraphicsBeginImageContextWithOptions(CGSize(width: 20, height: 104), false, scale);
    guard let context = UIGraphicsGetCurrentContext() else {return screenshotImage ?? UIImage(imageLiteralResourceName: "loading")}
    layer.render(in:context)
    screenshotImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    if let image = screenshotImage, shouldSave {
        UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)
    }
    return screenshotImage ?? UIImage(named: "loading")!
}

I expect that the screenshot taken, takes the screenshot of the imageview. Screenshot is attached,enter image description here

Try to use the code blocks in future questions, as it's much easier to read. — valosip, Oct 03 '19 at 02:03

I believe you're trying to say

You have 2 UIImageViews with different Images and then you want to take a screenshot of those 2 UIImageViews to make 1 image.

If that's the case, the easiest way to do solve it is to wrap those 2 UIImageViews inside a UIView. Then convert that UIView into UIImage. So you can have the Screenshot of those 2 UIImageViews in one.

In case you need code to convert UIView to UIImage:

extension UIView {
    func toImage() -> UIImage {
        let renderer = UIGraphicsImageRenderer(bounds: bounds)
        return renderer.image { rendererContext in
            layer.render(in: rendererContext.cgContext)
        }
    }
}

I'm not sure if this the solution to your problem.

Put those two image views inside a UIView, constraint them all properly. Then take a screenshot of that UIView. Follow this for screenshot: How to take screenshot of a UIView in swift?
