在非VC,NV,BV中找根视图来(比如:cell,view等)

NSLog(@"self.view next:%@", [self.superview.superview.superview nextResponder]);

UIViewController *viewCtl = (UIViewController *)[self.superview.superview.superview  nextResponder];

[viewCtl.navigationController pushViewController:[AddViewController new] animated:YES];

特别注释：self.superview.superview.superview

需要根据具体情况来调试 superview 的个数！
