I am using a UIButton in my application. This button title is displayed dynamically as per the user choice. Now i have to resize the button width as per the title content. I am calculating the string length and assigning it to button's width.

the button is resized as per title but the problem is as follows, 1. If at first the title with large content is shown and after that if a title with a small content is shown means the button is overwritten it doesn't remove the previously constructed value. 2. it looks as if one button is overlapped on the another.
