问题描述

如何在使用searchDisplayController时更改标签No Results？

how do I change the label "No Results", when using a searchDisplayController?

注意

推荐答案

它不能直接访问，所以你必须用老式的方式，手动筛选你的 searchDisplayController.searchResultsTableView的子视图。这里有一个例子：

It's not directly accessible, so you'll have to do it the old fashioned way and manually sift through the subviews of your searchDisplayController.searchResultsTableView. Here's one example:

UITableView *tableView = self.searchDisplayController.searchResultsTableView;
for( UIView *subview in tableView.subviews ) {
     if( [subview class] == [UILabel class] ) {
         UILabel *lbl = (UILabel*)subview; // sv changed to subview.
         lbl.text = @"My custom string";
     }
}

对 searchResultsTableView 的内部行为，这在某些时候很可能会改变，打破你的应用程序。与苹果打开错误/功能请求将是一个很好的方式去这里。

I wouldn't recommend this since you're relying on internal behavior of the searchResultsTableView which is more than likely going to change at some point, breaking your app. Opening a bug/feature request with Apple would be a good way to go here.
