Hello,
I'm going crazy with managing the Search Bar within the Storyboard
.
I've created my TableViewController and I've added the UISearchBar to the user interface. Everything seems ok, except for the "Search" button: I've created a method to hide the Search Bar, but I'm not able to intercept the button pressure.
Below my code:
Code:
// HelloSearchTableViewController_001.h
#import <UIKit/UIKit.h>
@interface HelloSearchTableViewController_001 : UITableViewController
{
NSMutableArray *listOfNames;
NSMutableArray *copyListOfNames;
IBOutlet UISearchBar *searchBar;
BOOL searching;
BOOL letUserSelectRow;
}
- (void) searchTableView;
- (void) doneSearching_Clicked:(id)sender;
//- (IBAction)doneSearching_Clicked:(id)sender;
- (IBAction)backgroundTouched:(id)sender;
@end
(I've tried to declare "doneSearching_Clicked" method in both "void" and "IBAction" manners, with no results)
Code:
// HelloSearchTableViewController_001.m
#import "HelloSearchTableViewController_001.h"
@implementation HelloSearchTableViewController_001
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
//---initialize the arrays---
listOfNames = [[NSMutableArray alloc] init];
copyListOfNames = [[NSMutableArray alloc] init];
//---add items---[listOfNames addObject:@"Alessandro"];[listOfNames addObject:@"Bruno"];[listOfNames addObject:@"Carlo"];[listOfNames addObject:@"Francesco"];[listOfNames addObject:@"Roberto"];[listOfNames addObject:@"Mauro"];[listOfNames addObject:@"Luca"];
[super viewDidLoad];
//Add the search bar
// self.tableView.tableHeaderView = searchBar;
searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
searching = NO;
letUserSelectRow = YES;
}
// raised when the user touches the search bar to bring up the keyboard
- (void) searchBarTextDidBeginEditing:(UISearchBar *)theSearchBar

searching = YES;
letUserSelectRow = NO;
self.tableView.scrollEnabled = NO;
}
// raised when a specified row is about to be selected

{
//prevents the user from selecting a row if the variable “letUserSelectRow” isn't set to true

The problem is with "doneSearching_Clicked" method, since I don't know how to tell to Xcode that when I press the Search button, this method must be invoked.
Thank you in advance for your support,
