【推荐阅读】微服务还能火多久？>>> 通过查看UISearchDispalyController的delegate方法以及它本身属性了解到他的一些方法，而通过测试，No Results字符的更改放到 - (void)searchDisplayController:(UISearchDisplayController *)controller willShowSearchResultsTableView:(UITableView *)tableView；方法中更为好一些，我看到有朋友放到shouldreload方法中的不过第一次还是会显示NO Results 所以效果不好，但是我测试，delegate方法shouldreload方法是发生在willShowSearchResultsTableView之前的，但是为什么更改默认的ResultsTableView的resultlable属性，shouldreload第一次不会改变，第二次执行shouldreload的时候就会显示“无结果”。但是如果你是在willShowSearchResultsTableView方法中更改的话，第一次就会显示效果。一下是我写的更改方法 - (void)searchDisplayController:(UISearchDisplayController *)controller

阅读更多关于 Where does filterContentForSearchText:scope: method come from?

问题 Recently, I noticed that filterContentForSearchText:scope: appeared in multiple tutorials regarding how to implement a search bar. However, I looked up the references of both UISearchDisplayDelegate and UISearchBarDelegate . I found this filterContentForSearchText:scope: is neither a required nor an optional method. I wondered if filterContentForSearchText:scope: is just a conventional method name for filtering search results? 回答1: Yes, that is only convention for a common method called from

问题 I am using a UISearchDisplayController to let the user search through a list of buildings on a university campus. Sometimes, the user will know exactly what building they want, enter the building's number, and that building will then be the only building result showing in the UITableView.

问题 I have a search bar at the bottom of a view. The issue is whenever I type something in the keyboard, the search bar still remains at the bottom and I cannot view what I am typing. I would like to dynamically move it up whenever the keyboards pops up and then take back its original position after the keyboard disappears. And unfortunately the search bar has to be in the bottom for my app and kind of stuck in this. Is there any way around to move the search bar up only when the keyboard appears
