设备旋转后垂直滚动条的尺寸错误

Question

I have a function where I make a UIScrollView and one more function for resizing UIView if InterfaceOrientation did change, but after rotating my vertical scroll bar has 1/3 the size of the width of my ScrollView.

wrapper.frame = CGRectMake(0,
                           cover_h + thumb_border*2,
                           startView.frame.size.width,
                           startView.frame.size.height-(cover_h+thumb_border*3));

wrapper.contentSize = CGSizeMake((int)thumb_w*2+thumb_border-1,(int) thumb_h*(slice/2)+thumb_border*((slice-1)/2));
wrapper.contentInset = UIEdgeInsetsMake(0, thumb_border, 0, thumb_border);

Code of formating ScrollView in init and resize is this same

I'm guessing the way you are resizing it is using the 'thumb' variables (_w, _h, _border). Are these being reset after the view is rotated? If they are set up to position everything correctly say for portrait view, when you switch to landscape view the sizes will all be wrong won't they? You might have to change those variables?
