Write a wrapper to get the image like

    if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)] == YES && [[UIScreen mainScreen] scale] == 2.00) {

        // RETINA DISPLAY
        NSString *jpegFile = [imageName stringByAppendingString:@"@2x.jpg"];
        image = [UIImage imageNamed:jpegFile];
    }
    else{

        NSString *jpegFile = [imageName stringByAppendingString:@".jpg"];
        image = [UIImage imageNamed:jpegFile];
    }

    return image;
}

And from your code call

bgImageView.image                   =   getImage(@"background");
