How to count number of lines in UITextField?

I need to count number of lines in my UITextField.

My UITextField has an array of UIBezierPath, to draw text along an UIImage.

UIBezierPath *rect = [UIBezierPath bezierPathWithRoundedRect:_image.frame cornerRadius:0];
[_txt addSubview:_image];
_txt.textContainer.exclusionPaths = @[rect];

Obviously, number of lines is different because there is an exclusion path and this common way,

 CGSize size  = [_txt.text
                sizeWithFont:_txt.font constrainedToSize:(CGSize){_txt.frame.size.width, INTMAX_MAX}
                lineBreakMode:NSLineBreakByWordWrapping];

returns a wrong result.

Note: _txt is an UITextField.

thanks.
