屏幕截图来自我的应用ios 10

Question

I want to screenshot display out of my app when an event occurred. I read these links( 1 , 2 , 3 ) but they aren't for ios 10. I want to know if I can do this.

Thanks

extension UIView {

public func toImage () -> UIImage {
    UIGraphicsBeginImageContextWithOptions(bounds.size, isOpaque, 0.0)
    drawHierarchy(in: bounds, afterScreenUpdates: false)
    let img = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return img!
}

}
