将uiview呈现为uiimage的问题

// 将UIView呈现为UIImage
func renderViewAsImage(view: UIView) -> UIImage? {
    UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.isOpaque, 0.0)
    defer { UIGraphicsEndImageContext() }
    guard let context = UIGraphicsGetCurrentContext() else { return nil }
    view.layer.render(in: context)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    return image
}

// 使用示例
let view = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
view.backgroundColor = UIColor.red
if let image = renderViewAsImage(view: view) {
    // 处理生成的UIImage
}
