在cell类拿到所在的控制器（不推荐）

1

• (UIViewController *)viewController
  {
  //获取当前view的superView对应的控制器
  UIResponder *next = [self nextResponder];
  do {
  if ([next isKindOfClass:[UIViewController class]]) {
  return (UIViewController *)next;
  }
  next = [next nextResponder];
  } while (next != nil);
  return nil;

}
界面跳转

[[self viewController].navigationController pushViewController:vc animated:YES];

[(UINavigationController *)[self getCurrentVC] pushViewController:vc animated:YES];//强转，把当前控制器对象强转成导航栏对象
