I am using ALAssetsLibrary to make an array of all images in the camera

  • 0

I am using ALAssetsLibrary to make an array of all images in the camera roll when my iPhone app starts. I store every image as a ALAsset * in an array.
Later in the app, I am saving an image to the gallery using this:

UIImageWriteToSavedPhotosAlbum(croppedImage, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);

The image is saved successfully to the saved photos album. But, now my problem is that when I try to retrieve images using the existing array of all images, I don’t get anything. Do I need to build the array of all images again or is there some other way to do this?

    Saving an image changes the library and invalidates objects like assets from the library. You need to reload assets from the library whenever the library changes – do that when you receive an ALAssetsLibraryChangedNotification.
