It's simple. You want to convert text to UIImage. Just draw text view's layer into Image context and convert into UIImage. code is below.

+ (UIImage *) imageWithView:(UITextView *)view
{
    UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0);
    [view.layer renderInContext:UIGraphicsGetCurrentContext()];

    UIImage * img = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return img;
}
