I got the answer and my working code is,

        float x=0;

        for(int i = 100; i < 110; i++)
         {
             btn = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];

             UIImage * img = [UIImage imageNamed:@"Round_Rect4.png"];

            [btn setBackgroundImage:img forState:UIControlStateSelected];

            titleString = [titleArray objectAtIndex:i-100];  // get button title

           CGSize fontSize = [titleString sizeWithFont:[UIFont systemFontOfSize:12.0]];

            CGRect currentFrame = btn.frame;

            CGRect buttonFrame = CGRectMake(x, currentFrame.origin.y, fontSize.width + 22.0, fontSize.height + 12.0);

           [btn setFrame:buttonFrame];

            x = x + fontSize.width + 35.0;

            [btn setTitle:titleString forState: UIControlStateNormal];

            [btn setTag:i];

            [self.view addSubview:btn];

}
