在使用self.imagePicker.mediaTypes = [(kUTTypeImage as String)]through 时，UIImagePicker我可以选择所有类型的图像，但我的要求是仅JPG, JPEG and PNG通过照片库选择类型图像，GIF并且HEIC不允许使用和（实时照片）。

那么，有什么方法可以阻止我选择GIF和HEIC类型的照片，同时imagePicker.sourceType = .photoLibrary

                            self.imagePicker.cameraCaptureMode = .photo
                            self.imagePicker.showsCameraControls = true
                            self.imagePicker.modalPresentationStyle = .overFullScreen
