从搜索结果表转到时UIBarButtonItem定位错误

我正在导航栏右侧创建一个UIBarButtonItem,代码如下:

-(void)setupImageTrashButton {
    UIButton *menuButton = [[UIButton alloc] init];
    UIImage *backgroundColor = [UIImage imageNamed:@"trash"];
    [menuButton setImage:backgroundColor forState:UIControlStateNormal];
    [[menuButton imageView] setContentMode:UIViewContentModeCenter];
    UIBarButtonItem *barMenuButtonItem = [[UIBarButtonItem alloc] initWithCustomView:menuButton];
    [menuButton addTarget:self action:@selector(delete) forControlEvents:UIControlEventTouchUpInside];
    self.navigationItem.rightBarButtonItem = barMenuButtonItem;
    self.navigationItem.rightBarButtonItem.style = UIBarButtonItemStyleBordered;
}

它可以正常工作,除非我从搜索结果表中找到该ViewController(单击搜索结果表单元格执行到该ViewController的segue)。错误的是按钮位置移动到导航栏的右侧。

知道吗?
