在iOS 7上双击带有搜索委托的UISearchBar会导致UISearchBar消失 [英] Double tap UISearchBar with search delegate on iOS 7 causes UISearchBar to disappear

问题描述

我们在表格标题中有一个搜索栏。当用户在iOS 7上快速点击两次时，它会消失。有没有人有任何建议我们做错了什么？

We have a search bar in the table header. When the user taps on it twice quickly on iOS 7, it disappears. Does anyone have any suggestions what we are doing wrong?

推荐答案

经过大量试验和错误，我发现当searchDisplayController结束搜索时，搜索栏消失，所以我已经将搜索栏重新插入到表头，它对我有效。

After lots of trial and errors, I found that when searchDisplayController ends search, searchbar gets disappear, so I have reinserted the searchbar to table header and it worked for me.

- (void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller
{
    self.searchingFetchedResultsController = nil;
    if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
        [self.tableView insertSubview:self.searchDisplayController.searchBar aboveSubview:self.tableView];
    }
    return;
}
