与UISearchBar \ UISearchDisplayViewController发生故障 [英] Troubles with UISearchBar \ UISearchDisplayViewController

问题描述

我在iOS 7上使用SearchDisplayViewController很难。
我在UITableViewController上隐藏了一个searchBar，比如

I'm having a hard time with my SearchDisplayViewController on iOS 7. I have a searchBar hidden over a UITableViewController, like

self.tableView.tableHeaderView = searchBar;

问题是，当我点击searchBar输入内容时，视图开始变灰，然后我在一个随机点上快速点击屏幕以关闭它，回到tableView，searchBar消失了。完全。仅在iOS 7上。

Problem is that when I tap on the searchBar to type in something, then the view starts greying out, and I quickly tap the screen in a random point to dismiss it, coming back to the tableView, the searchBar disappears. Totally. Only on iOS 7 though.

调试它，帧始终相同：0,0,320,44。但酒吧是看不见的！

Debugging it, the frame is always the same: 0,0,320,44. But the bar is invisible!

还试图做

self.tableView.contentOffset = CGPointMake(0,self.searchDisplayController.searchBar.frame.size.height);

当我快速完成时仍然会消失。

still disappears when I do it quickly.

在iOS 6上它运行得很好。问题只出现在我看到的iOS 7上。

On iOS 6 it works just fine. Problem is only with iOS 7 as far as I'm seeing.

我不知道它取决于什么，有没有人遇到过同样的问题？

I don't know what it depends on, has anyone encountered the same problem I have?

推荐答案

从在iOS 7上用搜索委托双击UISearchBar导致UISearchBar消失，我发现实际工作的解决方法并解决了错误 - 对于现在

As of Double tap UISearchBar with search delegate on iOS 7 causes UISearchBar to disappear, I found the workaround to actually work and solved the bug - for now.

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