在navigationItem中添加搜索栏
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。
补充：移动开发 , IOS ,
