clipsToBounds = false时，UIView的总体大小

Question

I have a UIView *view with its view.clipsToBounds = false . I have added subviews to it whose frames extend beyond the visible bounds of the view .

My question now is how to get the overall size of the view , including the extended subviews?

Answer 1

I am not able to understand why you want size of view including its subviews, but you can get it by looping through all subviews and applying simple calculations as following:

float x = 0, y = 0, endX = 0, endY = 0;

for (UIView *vw in yourview.subviews)
{
    CGRect rct = vw.frame;

    if(rct.origin.x < x)
        x = rct.origin.x;
    if(rct.origin.y < y)
        y = rct.origin.y;

    if(rct.size.width+rct.origin.x > endX)
        endX = rct.size.width + rct.origin.x;

    if(rct.size.height + rct.origin.y > endY)
        endY = rct.size.height + rct.origin.y;

}
