我有UIViewController的应用程序,它包含UISegmentView,UISearchDisplayController和UITableView,如图:
当我点击搜索栏时,一切都很好。出现键盘,我可以进行搜索活动。但是在我第二次点击搜索栏后,它消失了 - 在第二张图片上:
当我添加:
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {
self.searchDisplayController.searchResultsTableView.frame = CGRectMake(0, 20, self.tableView.frame.size.width, self.tableView.frame.size.height);
}
我可以在searchResultsTableView:
下看到搜索栏
有人能帮帮我吗?谢谢!
答案 0 :(得分:0)
好的,我终于有了解决方案,但同时我知道这不是最好的解决方案。
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {
CGRect newFrame = [self.view.superview convertRect:self.searchDisplayController.searchResultsTableView.superview.superview.frame toView:nil];
UIWindow *window = [UIApplication sharedApplication].keyWindow;
self.searchDisplayController.searchResultsTableView.superview.superview.frame = CGRectMake(0, -40, self.tableView.frame.size.width, window.bounds.size.height - newFrame.origin.y);
return YES;
}
和
- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar {
CGRect newFrame = [self.view.superview convertRect:self.searchDisplayController.searchResultsTableView.superview.superview.frame toView:nil];
UIWindow *window = [UIApplication sharedApplication].keyWindow;
self.searchDisplayController.searchResultsTableView.superview.superview.frame = CGRectMake(0, 4, self.tableView.frame.size.width, window.bounds.size.height - newFrame.origin.y);
return YES;
}
最后是内容大小:
- (void)searchDisplayController:(UISearchDisplayController *)controller didHideSearchResultsTableView:(UITableView *)tableView {
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}
- (void)searchDisplayController:(UISearchDisplayController *)controller willShowSearchResultsTableView:(UITableView *)tableView {
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide) name:UIKeyboardWillHideNotification object:nil];
}
- (void) keyboardWillHide {
UITableView *tableView = [[self searchDisplayController] searchResultsTableView];
[tableView setContentInset:UIEdgeInsetsZero];
[tableView setScrollIndicatorInsets:UIEdgeInsetsZero];
}
