Can you be more specific than "it doesn't work"?
你能比“它不起作用”更具体吗？

如果您尝试向已有项目的工具栏添加项目，则需要修改项目数组：
NSMutableArray *newItems = [self.toolbarItems mutableCopy];

self.toolbarItems = newItems;

Make sure you have make a toolbar either an IBOutlet or added toolbar programatically
确保您已将工具栏设为 IBOutlet 或以编程方式添加工具栏
IBOutlet UIToolbar *toolBar;
UIBarButtonItem *infoButtonItem=[[UIBarButtonItem alloc]initWithTitle:@"info" style:UIBarButtonItemStyleBordered target:self action:@selector(infoButtonClicked)];
toolBar.items = [NSArray arrayWithObjects:infoButtonItem, nil];

确保工具栏没有隐藏；您可以尝试将以下内容添加到您的视图控制器的viewWillAppear:animated:方法中：
[self.navigationController setToolbarHidden:NO animated:YES];
