#uisearchbar

This is how I fixed this issue. The answer by David Trang solved mine.

For some reason, it’s incredibly difficult to select text in a UISearchBar programmatically. I was specifically looking to reproduce something like Safari, where tapping the text to edit it would automatically select it all. This allows the text to remain and gives easy access to copying as well as starting a new search without hitting the X button to clear the current one. After much searching, I found a pretty simple, albeit a little hacky, solution. I’m posting the code for hopes that it helps someone in the future.

func searchBarTextDidBeginEditing(searchBar: UISearchBar) { NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: "selectSearchBarText", userInfo: nil, repeats: false) } func selectSearchBarText() { UIApplication.sharedApplication().sendAction("selectAll:", to: nil, from: nil, forEvent: nil) }

If we have a huge list of items and want to search a item from the list then we use the UISearchBar with TableView and the item will be displayed in the table which have the matching value with the search text.

Here are the steps:

Step1: Add UITableView to the main.storyboard. Step2: set the delegate and dataSource for the tableView Step3: Create the outlet for tableView with following Syntax __weak IBOutlet UITableView *myTableView;

Since UISearchBar is found in my table's header view, I just implement this line of code in order to remove it from the table:

self.tableView.tableHeaderView = nil;

When I want to make it reappear, I just implement this code:

self.tableView.tableHeaderView = self.mySearchBar;

How to filter NSFetchedResultsController (CoreData) with UISearchDisplayController/UISearchBar

I’m trying to implement search code in my CoreData-based iPhone app. I’m not sure how to proceed. The app already has an NSFetchedResultsController with a predicate to retrieve the data for the primary TableView. I want to make sure I’m on the right path before I change too much code. I’m confused…

This is very easy to do with storyboards with ONE key detail to remember1. But I struggled for a bit. Most of the examples that I saw did not highlight the key detail.

Basic idea of how it works:

The search bar controller has a separate tableview that it populates with the results of your search.

It populates its tableview with the same methods, though.

So you create a separate datasource that is filled with the results of your search, and fill the tableview accordingly.

But first, Here is the simplest way:

In your Storyboard, drag searchBar And Controller onto your tableview. You get all the delegate setup for free.

add <UISearch1. create an NSArray property to hold the objects from the search results.

you need to make four simple changes to your code

The first, and least obvious to me. in your cellForRowAtIndexPath method, you need to change UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; to UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

return the row count - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return (tableView == self.searchDisplayController.searchResultsTableView)?self.searchObjects.count:self.objects.count; }

After dequeuing Cell as shown above, set the Cell's content with the correct data source. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ... cell.textLabel.text = (tableView == self.searchDisplayController.searchResultsTableView)?self.searchObjects[indexPath.row]:self.objects[indexPath.row]; return cell; }

Use the searchDisplayController delegate method to return the revised datasource according to whatever predicate you would like to use: -(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:@"description contains[c] %@", searchString]; self.searchObjects = [[NSArray arrayWithArray:self.objects] filteredArrayUsingPredicate:resultPredicate]; return YES; } NOTE" "description" should be replaced with whatever property of the object that fills the array or datasource of your tableView. (another good reason to fill in the description property of your custom objects...

NOT NECESSARY, but nice is to add <UISearchBarDelegate, UISearchDisplayDelegate> to the interface declarations. It gives you method completion for free if you are using any of the delegate methods.

That's it. If using storyboards, then you don't even need to declare the searchDisplayControllerDelegate protocol up top as storyboard takes care of that for you.
