所要截取的对象
var bg_view: UIView!
截取并且保存的代码如下
UIGraphicsBeginImageContextWithOptions(bg_view.frame.size, false, UIScreen.main.scale) bg_view.layer.render(in: UIGraphicsGetCurrentContext()!) let image = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() UIImageWriteToSavedPhotosAlbum(image!,self,#selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
