在我们的应用程序中,我们有一个具有 UISearchController 的 UITableViewController:
searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
[self.searchController.searchBar sizeToFit];
self.tableView.tableHeaderView = self.searchController.searchBar;
self.showFooterView = YES;
self.searchController.delegate = self;
self.searchController.dimsBackgroundDuringPresentation = NO; // default is YES
self.searchController.searchBar.delegate = self;
self.definesPresentationContext = YES;
表视图控制器也是一个 UISearchBarDelegate 和 UISearchControllerDelegate。
#pragma mark - UISearchBarDelegate
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
[searchBar resignFirstResponder];
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
self.contacts = self.allContacts;
[self.tableView reloadData];
}
现在一切正常,但有时用户开始搜索,在搜索栏中输入几个字符,返回结果,用户取消搜索,然后发生这种情况:
Fatal Exception: NSInvalidArgumentException

尽管 Fabric 在生产中报告了此错误,但我们从未能够重现此错误。
这个问题看起来类似于:Selecting cell after search doesn't segue 在视觉上,但会加载下一个视图 Swift Xcode但尚未给出真正的答案。
我已经开始研究演示控制器,但我们没有需要以特定方式设置演示控制器的特殊功能。
有想法该怎么解决这个吗?
谢谢
