跳过普通的设置左右按钮我们直接讲解给导航栏设置多个按钮实现代码如下

<span style="font-size:18px;">UIToolbar *tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 45)];</span>

<span style="font-size:18px;">    [tools setTintColor:[self.navigationController.navigationBar tintColor]];</span>

<span style="font-size:18px;">    [tools setAlpha:[self.navigationController.navigationBar alpha]];</span>

<span style="font-size:18px;">    NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:2];    </span>

<span style="font-size:18px;">    UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(clickSettings:)];</span>

<span style="font-size:18px;">    UIBarButtonItem *anotherButton1 = [[UIBarButtonItem alloc] initWithTitle:@"编辑" style:(UIBarButtonItemStylePlain) target:self action:@selector(clickEdit:)];</span>

<span style="font-size:18px;">    anotherButton1.tintColor = [UIColor redColor];        [buttons addObject:anotherButton];</span>

<span style="font-size:18px;">    [buttons addObject:anotherButton1];        [tools setItems:buttons animated:NO];        UIBarButtonItem *myButton = [[UIBarButtonItem alloc] initWithCustomView:tools];        self.navigationItem.rightBarButtonItem = myButton;</span>

<span style="font-size:18px;">- (void)clickSettings:(UIBarButtonItem *)clickSettings{    NSLog(@"我是添加按钮");}</span>

<span style="font-size:18px;">- (void)clickEdit:(UIBarButtonItem *)clickEdit{    NSLog(@"我是编辑按钮");}</span>
