在ios中自定义导航栏

Question

I used Navigation Controller & navigation Bar in StroryBoard .

I want to customize navigation Bar for one view as follow for right side of navigation bar.

My tried code

    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];

Problem of tried code: There is a space between two buttons.

How can I achieve this?

Answer 1

只需使用分段控制：你有一个完整的例子这里

Answer 2

declare a segment control with custom view

UISegmentedControl *control = (UISegmentedControl *) [segmentBarButton customView];

and then add it to barbuttonitem view

UIBarButtonItem *segmentBarButton=[[UIBarButtonItem alloc] initWithCustomView:control];

dont forget to write the lines that relates to segment control customized view like ur requirement adding red or black images to the segment 0 or 1.
