是一条显示上面可以放一些东西如UiBarButtonItem

首先创建两个 UIBarButtonItem

UIBarButtonItem *mybb1 = [[UIBarButtonItem alloc]initWithTitle:@"MYBB1" style:UIBarButtonItemStylePlain target:self action:@selector(item1Action)];    UIBarButtonItem *mybb2 = [[UIBarButtonItem alloc]initWithTitle:@"MYBB1" style:UIBarButtonItemStylePlain target:self action:@selector(item2Action)];

再创建一个UIBarbuttonItem的Label

UILabel *mytblabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];    mytblabel.text = @"title";    UIBarButtonItem *mybarLabel = [[UIBarButtonItem alloc]initWithCustomView:mytblabel];

然后创建UIToolbar 并把三个Item加到toolbar里

NSArray *myItems = [NSArray arrayWithObjects:mybb1,mybb2,mybarLabel,nil];UIToolbar *myDemoToolBar = [[UIToolbar                  alloc]initWithFrame:CGRectMake(0, 200,  self.view.bounds.size.width, 40)];myDemoToolBar.barStyle = UIBarStyleBlack;myDemoToolBar.alpha = 0.3;myDemoToolBar.items = myItems;[self.view addSubview:myDemoToolBar];

接下来再实现两个selector，一个显示UIAlertView，一个显示UIActionSheet

- (void) item1Action{    UIAlertView *myAlertView = [[UIAlertView alloc]initWithTitle:@"标题" message:@"继续" delegate:self cancelButtonTitle:@"false" otherButtonTitles:@"yes", nil];    [myAlertView show];}- (void) item2Action{    UIActionSheet *myActionSheet = [[UIActionSheet alloc]initWithTitle:@"title" delegate:self cancelButtonTitle:@"cancle" destructiveButtonTitle:@"yes" otherButtonTitles:@"go on",@"pause", nil];    [myActionSheet showInView:self.view];}
