给navigationItem中添加个搜索栏，效果和大部分程序一样。代码如下：

UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 200, 28)];

searchBar.backgroundImage = [UIImage imageNamed:@"btu_search"];

searchBar.placeholder = @"搜索";

searchBar.delegate = self;

UIBarButtonItem *searchButton = [[UIBarButtonItem alloc]initWithCustomView:searchBar];

self.navigationItem.rightBarButtonItems = [NSArray arrayWithObject:searchButton];

最后在- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar 方法里面写搜索方法就可以了。比较简单，做个记录。
