ALAsset pointer throw EXC_BAD_ACCESS when accessing it

I am developing an image gallery that allows me to select some images from the iPhone and display them.

Some explanations about this gallery:

  • UITableView Displays various directories containing iPhone pictures
  • When the user clicks on one of these directories: Display UICollectionViewwith different images from the selected directory
  • Back button to return to UITableView
  • The next button to display the selected images on a new page.

How this gallery is implemented:

  • For each directory found on iPhone images, save ALAssetsGroupin NSMutableArraynamed directoriesData li>
  • Display directories stored in Data directories, in UITableView.
  • When the user selects one directory: store each of the ALAssetcontained in this directory in NSMutableArraythe name picturesData.
  • Display thumbnails in UICollectionViewfrom images.
  • When the user selects an image, it is saved in a single instance NSMutableArraynamed wishPictures.
  • If the user clicks the back button, I delete all objects from the Data images before displaying UITableView.

Now the problem is:

I have two different image catalogs on my iPhone.

Directory A Directory B

I want to select one image in Catalog A and another in Catalog B.

After selecting them, I click on the next page to display them.

. , ALAsset A, EXC_BAD_ACCESS.

, pictureData ( ), EXC_BAD_ACCESS.

pictureData, , UICollectionView . A, B, UICollectionView.

, ALAsset PictureData?
