Create, Delete, and add pictures to albums in the photos app? - iphone

Question

Haven't seen anything, but I have seen that you can create albums in the iOS 5 photos.app, and I was curious if there is a way to integrate it in my app.
I need to be able to create the album, upload pictures to it, and be able to delete it.
Thanks,
Coulton

Answer 1

Since iOS5 you can programmatically add albums to Photos. See the ALAssetsLibrary Class Reference.
You can add an album (which is an ALAssetsGroup) with:
addAssetsGroupAlbumWithName:resultBlock:failureBlock:
Every ALAssetsGroup has a URL associated with it. You'll want to save it:
valueForProperty:ALAssetsGroupPropertyURL
You can then use that URL to get an ALAssetsGroup object:
groupForURL:resultBlock:failureBlock:
Once you have your ALAssetsGroup you can use addAsset: method on it to add an image or video.
Notice: all these methods are asynchronous and return immediately. You do the actual work in the blocks you pass to these methods.

Answer 2

See the UIImage class reference:
http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImage_Class/Reference/Reference.html
void UIImageWriteToSavedPhotosAlbum (
UIImage *image,
id completionTarget,
SEL completionSelector,
void *contextInfo
);
http://developer.apple.com/library/ios/#documentation/uikit/reference/UIKitFunctionReference/Reference/reference.html#//apple_ref/c/func/UIImageWriteToSavedPhotosAlbum
Adds to the camera roll album (camera) or saved photos album (no camera).
