Question

Is it possible to save images captured by the camera on the iphone to a custom directory or somewhere on the iphone rather than saving to the camera roll?

I would like to save images to the device and then have access to the at a later stage, rather than reading from the camera roll using ALAssets.

Is this possible?

Yes you can save them to your apps’ documents folder. Here is an example:

// Create path
NSString  *imagePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/ImageName.png"];

// Write image to PNG
[UIImagePNGRepresentation(image) writeToFile:imagePath atomically:YES];

To retrieve it:

UIImage *image = [UIImage imageWithContentsOfFile:imagePath];

To list all files in a directory:

NSFileManager *manager = [NSFileManager defaultManager];
NSArray *fileList = [manager directoryContentsAtPath:[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]];
for (NSString *s in fileList){
    NSLog(s);
}
