//左侧item
UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRewind target:self action:@selector(barButtonClick:)];
//设置唯一的标签
leftButton.tag = 101;
//添加到导航条上
self.navigationItem.leftBarButtonItem = leftButton;
//添加一个右侧的按钮
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFastForward target:self action:@selector(barButtonClick:)];
rightButton.tag = 102;
self.navigationItem.rightBarButtonItem = rightButton;
//设置navigationItem的标题
self.navigationItem.title = @"我的歌声里";
//设置副标题
self.navigationItem.prompt = @"曲婉婷";
//再创建一个UIBarButtonItem类型的按钮
UIBarButtonItem *leftButton1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemPause target:self action:@selector(barButtonClick:)];
//设置左视图(多个按钮)
NSArray *leftBarButtonArray = @[leftButton,leftButton1];
//把这个数组设置给自动扩展位置 navigationItem.leftBarButtonItems 属性
