Thanks! 回答1: If the segments are equal, why not just divide the width of the control by the number of the selected segment (+1 because numbering starts at 0)? EDIT: Like this -(void)showPopover:(id)sender {

问题 I'm generating an UIWebView into my viewDidLoad method, with a tiny size (let's say something like 50x70). And then I put it into a super UIView. I'd like to make its content fit the webView frame.
