I compiled and ran the MyImagePicker project from the WWDC 2010 sample code on my iPhone 3Gs with iOS 4.2.1, but it just gives me a blank table. Shouldn t it be populating with data from my photo roll?
Interestingly, I also get a blank table in the UIImagePickerController Clone from iCodeBlog.
Both of these projects apparently use the AssetsLibrary framework -- what am I missing here?
I shouldn t have assumed that the picker would automatically select from the saved photos album.
Change the following line in RootViewController.m from:
NSUInteger groupTypes = ALAssetsGroupAlbum | ALAssetsGroupEvent | ALAssetsGroupFaces;
to:
NSUInteger groupTypes = ALAssetsGroupSavedPhotos;
to just get saved photos... It turns out that this isn t any better for my purposes than the stock UIImagePickerController, but it was a learning experience.
