推荐答案

尝试一下，传入包含您需要的所有子视图的基本视图:

Try this, passing in the base view that has all the subviews you need:

func createImage(from aView:UIView) -> UIImage {
    UIGraphicsBeginImageContextWithOptions(CGSize(width: aView.frame.width, height: aView.frame.height), true, 0)
    aView.layer.render(in: UIGraphicsGetCurrentContext()!)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image!
}
