ios - ios自定义导航栏

Question

我在 StroryBoard 中使用了 Navigation Controller 和 navigation Bar。

我想为一个 View 自定义导航栏，如下所示，用于导航栏的右侧。

我试过的代码

    UIButton *btn_list=[UIButton buttonWithType:UIButtonTypeCustom];
    btn_list.frame=CGRectMake(0, 0, 60, 30);
    [btn_list setTitle:@"Liste" forState:UIControlStateNormal];
    [btn_list setBackgroundImage:[UIImage imageNamed:@"red-left.png"] forState:UIControlStateNormal];
    [btn_list setBackgroundImage:[UIImage imageNamed:@"black-left.png"] forState:UIControlStateSelected];
    UIBarButtonItem *list_bar=[[UIBarButtonItem alloc]initWithCustomView:btn_list];
    
    UIButton *btn_map=[UIButton buttonWithType:UIButtonTypeCustom];
    btn_map.frame=CGRectMake(0, 0, 60, 30);
    [btn_map setTitle:@"Karte" forState:UIControlStateNormal];
    [btn_map setBackgroundImage:[UIImage imageNamed:@"red-right.png"] forState:UIControlStateNormal];
    [btn_list setBackgroundImage:[UIImage imageNamed:@"black-right.png"] forState:UIControlStateSelected];
    UIBarButtonItem *map_bar=[[UIBarButtonItem alloc]initWithCustomView:btn_map];

    self.navigationItem.rightBarButtonItems=[[NSArray alloc]initWithObjects:list_bar,map_bar, nil];

试过的代码问题:两个按钮之间有一个空格。

我怎样才能做到这一点？
