使用自定义名称将照片保存到iphone相机胶卷

Question

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，无法使用自定义名称保存到相机胶卷。

Answer 2

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.

See details (and code) at http://ootips.org/yonat/how-to-set-the-image-name-when-saving-to-the-camera-roll/ .
