导航栏（Navigation）上多个点击事件

在开发中经常会出现导航栏右侧需要两个或者三个点击事件，这样就需要设置多个点击事件。

代码：

  UIToolbar *tools=[[UIToolbar alloc]initWithFrame:CGRectMake(5, 0, 120, 45)];
    //解决出现的那条线
    tools.clipsToBounds = YES;
    //解决tools背景颜色的问题
    [tools setBackgroundImage:[UIImage new]forToolbarPosition:UIBarPositionAny                      barMetrics:UIBarMetricsDefault];
    [tools setShadowImage:[UIImage new]
       forToolbarPosition:UIToolbarPositionAny];
    //添加两个button
    NSMutableArray*buttons=[[NSMutableArray alloc]initWithCapacity:2];
    //第一个按钮
    UIBarButtonItem *button1=[[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@""] style: UIBarButtonItemStyleDone target:self action:@selector(shareTaepd:)];
    //设置title
    [button1 setTitle:@"分享"];
     //设置title颜色
    [button1 setTintColor:[UIColor blackColor]];

    UIBarButtonItem *button2=[[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@""] style: UIBarButtonItemStyleDone target:self action:@selector(releaseTaepd:)];
    [button2 setTintColor:[UIColor blackColor]];
    [button2 setTitle:@"发布"];

    [buttons addObject:button1];
    [buttons addObject:button2];

    [tools setItems:buttons animated:NO];
    UIBarButtonItem*btn=[[UIBarButtonItem    alloc]initWithCustomView:tools];
    self.navigationItem.rightBarButtonItem=btn;

这样实现方法shareTaepd: 和releaseTaepd:就可以分别完成点击分享和发布的点击事件了。
