Save photo to iphone camera roll with a custom name
I am trying to save a photo taken from my app to camera roll, this can be done by using UIImageWriteToSavedPhotosAlbum, however, I noticed there isn't any way to set the photo name by using this approach, am I right?
I also tried to save a image file with a name by using UIImageJPEGRepresentation, however, I can only save it to my app's document folder but not camera roll.
Is there any way to save photo to camera roll with a custom name?
Thanks advance for your kindly help.

不，没有办法用自定义名称保存到相机胶卷。
There is a way to kinda do that, by setting the image metadata:
if you set the IPTC metadata field "Object Name", this will be shown as the image title in iPhoto.
