This method returns a size that is obtained by calling the Uikit subclass, which is the perfect fit to call the size of the Uikit subclass of this method  
after this size is obtained, you can invoke the method to resize the frame * * preferredcontentsize** with
"//Reset the size of this controller
-(cgsize) preferredcontentsize{

    if ( Self.popoverpresentationcontroller!= nil) {
        cgsize tempsize;
        Tempsize.height = self.view.frame.size.height;
        Tempsize.width  = A;
        Cgsize size = [_tableview sizethatfits:tempsize];  Returns the size of a perfect fit tableview
        ;
    else{return
        [Super Preferredcontentsize];
    }
