调用底层的viewController--返回底层

//返回底层viewController的方法--- (UIViewController*)GetViewController:(UIView*)uView{    for (UIView* next = [uView superview]; next; next = next.superview) {        UIResponder* nextResponder = [next nextResponder];        if ([nextResponder isKindOfClass:[UIViewController class]]) {            return (UIViewController*)nextResponder;        }    }    return nil;}

//调用示例--[[self GetViewController:self.parentViewController.view] presentViewController:detailPAGE animated:YES completion:nil];
