Question

I’m trying to save Images the user takes with the camera

1) If I use the UIImageWriteToSavedPhotosAlbum I can’t seem to assign the fileName that I want. How, can you choose the file name?
The nice thing about using this option is
[picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
Then gives a thumbnail gallery of Photo Library directory.

2) which leads me to my next question Can
[picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
be used to get images from your own personal directory ?

3) Is there anyway to programmatically create sub folders within the Photo Library

4) Lastly,

NSArray  *paths    = NSSearchPathForDirectoriesInDomains(NSPicturesDirectory, NSUserDomainMask, YES);
if (![[NSFileManager defaultManager] fileExistsAtPath:[paths objectAtIndex:0] isDirectory:&isDir]) {
        NSError  *error;
        [[NSFileManager defaultManager] createDirectoryAtPath:[paths objectAtIndex:0 withIntermediateDirectories:YES attributes:nil error:&error];
}

Checking to see if the NSPicturesDirectory exists so I can write to it
I keep getting a Cocoa error 513 not permitted

Thanks in advance

You can’t assign a file name to photo library images. ios assign a file name called asset url to the images that are saved to the photo library, we can’t change that.

If you need to save the images to photo library you can use ALAssetsLibrary

    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
   [library writeImageToSavedPhotosAlbum:[image CGImage] orientation:(ALAssetOrientation)     [image imageOrientation] completionBlock:^(NSURL *assetURL, NSError *error){
    if (error)
    {
     // Eror
    }
    else
    {
     // Success
    }
   }];
   [library release];
