Stretch background image for UIButton

Question

I got texture, which really shorter, than my UIButton.

I got this texture:

Answer 1

Or using Stretchable Images:

UIImage* imgbkg =[[UIImage imageNamed: @"my_bkg_image.png"] stretchableImageWithLeftCapWidth:10 topCapHeight:10];

[_button setBackgroundImage: imgbkg forState: UIControlStateNormal];

Use 0 if you don't want to stretch certain side.
