UISearchBar * searchbar = [[UISearchBar alloc]initWithFrame:CGRectMake(0.0f, 0.0f, 255.0f, 44.0f)]; searchbar.delegate = self;
[searchbar setTintColor:[UIColor redColor]];
[searchbar setPlaceholder:@"搜索游记、旅行地与用户"];
UIBarButtonItem * searchButton = [[UIBarButtonItem alloc]initWithCustomView:searchbar];
self.navigationItem.rightBarButtonItem = 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。
