Answer 1

I use this codes for load picture from documents directory, i guess you can make it with same codes

- (UIImage*)loadImage:(NSString*)imageName {

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", imageName]];

UIImage *graphImage = [[UIImage alloc] initWithContentsOfFile: fullPath];
img1.image = graphImage;

return [UIImage imageWithContentsOfFile:fullPath];
}

call this method like this

[ self loadImage: "your image name"];

You can use this code for getting the document directory path in C# script it might be helpful

   public static string GetiPhoneDocumentsPath ()
{
// Application.dataPath returns
// /var/mobile/Applications/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/myappname.app/Data
// Strip "/Data" from path
string path = Application.dataPath.Substring (0, Application.dataPath.Length - 5);
// Strip application name
path = path.Substring(0, path.LastIndexOf('/'));
return path + "/Documents";
}
