我想在Searchdisplaycontroller

Question

我想在搜索控制器中更改无结果的颜色。我可以改变搜索表背景颜色单独的indexcolor。

Answer 1

尝试这样，

创建一个属性

@property (nonatomic, strong) UISearchController * searchController;

然后添加以下内容：

// When the user types in the search bar, this method gets called.
- (void)updateSearchResultsForSearchController:(UISearchController *)aSearchController {

//// .. do whatever your search results..

     for (UIView *subview in ((UITableViewController *)self.searchController.searchResultsController).tableView.subviews) {
         if ([subview isKindOfClass:[UILabel class]]) {
            if ([((UILabel *)subview).text isEqualToString:@"No Results"]) {
               ((UILabel *)subview).textColor = [UIColor redColor];
            }
         }
      }
}

编辑回答：

for (UIView *subview in self.searchDisplayController.searchResultsTableView.subviews) {
        if ([subview isKindOfClass:[UILabel class]]) {
            if ([((UILabel *)subview).text isEqualToString:@"No Results"]) {
                ((UILabel *)subview).textColor = [UIColor redColor];
            }
        }
    }
