我有一个教程中的代码:
// Do the search and show the results in tableview
// Deactivate the UISearchBar
// You'll probably want to do this on another thread
// SomeService is just a dummy class representing some
// api that you are using to do the search
NSArray *results = [SomeService doSearch:searchBar.text];
什么是 SomeService 以及如何下载它?
(我在谷歌搜索。)
