UITableview Delegate methods are not executing - ios

Question

i tried the following code for searching in epub ,Its not working the reason is
1.The table delegate methode executing at startup so the default value of search results is 0 ,so i give one dummy array with 4 elements in viewdidload method.So now tableview displaying only 4 thode elements in dummy array and when i scroll the tableview it displaying correct search results but still it showing only 4 elemets in that search results because number of rows methode is not execute while scrolling.
when i click search button it will call this methode in first class
SearchResultsViewController *searchRes=[[SearchResultsViewController alloc]initWithNibName:#"SearchResultsViewController" bundle:nil];
NSString *searchQuery=[search text];
sharedManager=[Mymanager sharedManager];
sharedManager.searchQuery=searchQuery;
// UITextField *textField = [NSString stringWithFormat:#"%#",searchQuery];
// [textField setFont:[UIFont fontWithName:#"BL-Ruthika-Bold" size:15]];
[searchRes searchString:searchQuery];
[self.navigationController pushViewController:searchRes animated:YES];
then it calls following methods in searchresult class
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
NSLog(#"%d",[results count]);
if([results count]>0)
{
return [results count];
}
else
{
return [test count];
}
}
//executes only at the startup time ,so the value of results always become zero
- (UITableViewCell *)tableView:(UITableView *)tableView1 cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
if([results count]>0) {
// cell.textLabel.adjustsFontSizeToFitWidth = YES;
hit = (SearchResult*)[results objectAtIndex:[indexPath row]];
cell.textLabel.text = [NSString stringWithFormat:#"...%#...", hit.neighboringText];
cell.detailTextLabel.text = [NSString stringWithFormat:#"Chapter %d - page %d", hit.chapterIndex, hit.pageIndex+1];
cell.textLabel.font = [UIFont fontWithName:#"Trebuchet MS" size:13];
cell.textLabel.textColor = [UIColor colorWithRed:25/255.0 green:90/255.0 blue:100/255.0 alpha:1];

cell.detailTextLabel.font= [UIFont fontWithName:#"Trebuchet MS" size:10];
return cell;
}
else
{

return cell;
}
}

Answer 1

When you have received your search results call
[self.tableView reloadData];
To tell the table view to update itself. I can see you have tried it a number of times in the large amount of code above. You only need to call it once, when you have your search results ready. Also, ensure your reference to the table view is valid when you call it.
Also, if you're creating a table view in an XIB file, then the second one you're creating in viewDidLoad and not showing (adding as a subview) is just confusing you and you're trying to reload the wrong table view.
If you still have problems, show the class properties and remove all the code tat isn't to do with the table view.

Answer 2

resultsTableView=[[UITableView alloc]init];
Try to use resultsTableView, with a property, and set it's to (nonatomic, strong).
