先看效果避免耽搁大家时间

裁剪效果

没有代码示范的代码不是好代码，附上demo

代码使用：

funcimagePickerController(_picker:UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey:Any]) {

        picker.dismiss(animated:false, completion:nil)

        letimage = info[.originalImage]as!UIImage

        letcropperImage =RImageCropperViewController.init(originalImage: image, cropFrame:CGRect.init(x: (kScreenWidth-300)/2, y: (kScreenHeight-300)/2, width:300, height:300), limitScaleRatio:30)

        cropperImage.delegate=self

        navigationController?.pushViewController(cropperImage, animated: true)

    }
