问题 I'm trying to filter a UITableView's data using a UISearchDisplayController and NSCompoundPredicate . I have a custom cell with 3 UILabels that I want to all be filtered within the search, hence the NSCompoundPredicate . // Filter the array using NSPredicate(s) NSPredicate *predicateName = [NSPredicate predicateWithFormat:@"SELF.productName contains[c] %@", searchText]; NSPredicate *predicateManufacturer = [NSPredicate predicateWithFormat:@"SELF.productManufacturer contains[c] %@", searchText

问题 I need to make the table view inside the UISearchDisplayController class to be a custom class which extends from UITableView .

问题 I have a UITableViewController with a UISearchDisplayController setup in the standard way (with the search bar inside the tableView). I'd like the search bar to start out hidden - really hidden, not merely scrolled away as in this solution. Then I'd like to present the search UI when the user presses a button, and hide it again (really hide it) after the user selects one of the items found in the search. Here's the almost working code for that: - (void)viewWillAppear:(BOOL)animated { [super

问题 I am pretty new in IOS and I am using UISearchDisplayController for searching. -(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { [self filterContentForSearchText:searchString scope:[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]]; return YES; } - (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*

问题 I have a simple table view inside a navigation controller with the toolbar visible. On the toolbar is a search button, and the table view's table header view is set to my UISearchBar . If I scroll the table view up and then tap on the search bar to activate it, everything happens normally. But if I tap on the search button, which activates search bar programmatically, then all interactions with the search bar are disabled (looks like it's blocked by something), and the user can't clear the

问题 I have standard iPad view controller which has a custom navigation bar at the top. In the xib-file I've added a UISearchBar aligned to the right edge of the view. The search bar is 320px in width.

问题 I've read so many solution on how can i focus a searchbar to make keyboard appear when i open my search view, and all of that are like this [searchBar becomeFirstResponder]; mine is [self.searchDisplayController.searchBar becomeFirstResponder]; but I tried both. Now, I tried this, and I also added a [self.searchDisplayController setActive:YES]; because I'm using a SearchDisplayController, but so far the best result i can have is to have the cursor on the searchbar, the uitableview with an

问题 I am using UISearchController to display a search bar and results within a UITableView. I managed to set it up correctly, but when I search the results and then select one of the rows in the tableview, and push a new view controller to the navigation stack, I would expect the search bar to not be visible anymore. However, when I try this, the search bar from the first view controller is visible in the 2nd view controller: if (self.searchController == nil) { self.searchController = [
