How to reload UITableView after the UISearchBar ends editing - objective-c

Question

I created a UISearchBar. It is working but not the way I want. If I enter any first letter on the UISearchbar and then I click on the SearchButton, it doesn't work but when I push the next controller and I come back, then I see my search result in TableView. The first time my TableView does not refresh.
Here is my custom cell class and my controller class
#synthesize myTableView;
#synthesize tabledata;
#pragma mark -
#pragma mark Initialization
#pragma mark -
#pragma mark View lifecycle
-(void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.leftBarButtonItem = self.editButtonItem;
app = (JourneyAppDelegate *)[[UIApplication sharedApplication]delegate];
sBar =[[UISearchBar alloc]initWithFrame:CGRectMake(0, 0, 320, 30)];
sBar.delegate=self;
[self.view addSubview:sBar];
searcheddata =[[NSMutableArray alloc]init];
NSLog(#"*************:%&",list);
list=[[NSMutableArray alloc]init];
tabledata =[[NSMutableArray alloc]init];
list = [app.journeyList retain];
[tabledata addObjectsFromArray:list];
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 100.0;
}
#pragma mark -
#pragma mark Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [tabledata count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"*************:%&",list);
static NSString *CellIdentifier = #"Cell";
TJourneyListCell *cell =(TJourneyListCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[TJourneyListCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
NSLog(#"%#",cell);
}
NewJourney *newjoruneobject = [tabledata objectAtIndex:indexPath.row];
cell.namelbl.text = newjoruneobject.journeyname;
cell.distancelbl.text = newjoruneobject.journeylocation;
cell.infolbl.text = newjoruneobject.journeydescription;
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
return cell;
}
#pragma mark UISearchBarDelegate
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
// only show the status bar’s cancel button while in edit mode
[tabledata removeAllObjects];
sBar.showsCancelButton = YES;
[searchBar setShowsCancelButton:YES animated:YES];
sBar.autocorrectionType = UITextAutocorrectionTypeNo;
}
- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar
{
searchBar.showsCancelButton = NO;
}
- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
[tabledata removeAllObjects];// remove all data that belongs to previous search
if([sBar.text length] != 0)//|| searchText==nil)
{
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"journeyname contains[cd] %#", searchBar.text];
[tabledata addObjectsFromArray:[list filteredArrayUsingPredicate: predicate]];
[myTableView reloadData];
return;
}
NSLog(#"Counter:-'%d'",[tabledata count]);
[myTableView reloadData];
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{ // if a valid search was entered but the user wanted to cancel, bring back the main list content
[tabledata removeAllObjects];
[tabledata addObjectsFromArray:list];
#try
{
[myTableView reloadData];
}
#catch(NSException *e)
{
}
[sBar resignFirstResponder];
sBar.text = #" ";
}
// called when Search (in our case “Done”) button pressed
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
[searchBar resignFirstResponder];
myTableView.allowsSelection = YES;
myTableView.scrollEnabled = YES;
[myTableView reloadData];
}
- (void)dealloc {
[super dealloc];
[mLable1 release];
[myTableView release], myTableView = nil;
[tabledata dealloc];
}
#end

Answer 1

- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar
{
searchBar.showsCancelButton = NO;
[myTableView reloadData];
}
I was having difficulties with this as well until I got to this post. I looked through your functions and decided to throw the reload data in the function above it works fine now! Hope this helps!

Answer 2

- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[tableView reloadData];
}

Answer 3

You can use this delegate method to reload table, after search table disappears:
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar

Answer 4

Swift version
func searchBarTextDidEndEditing(searchBar: UISearchBar) {
searchActive = false //Local variable used to manipulate your cells
self.newsTableView.reloadData()
}
