Question

Here is my code below:

- (UITableViewCell *)tableView:(UITableView *)tableView1 cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
        
    NSInteger row = [indexPath row];
    NSString *contentForThisRow = nil;
    NSString *contentForThisRow2 = nil;
    
    if (mySearchBar.text > 0)
    {
        contentForThisRow = [self.filteredListContent objectAtIndex:row];
        NSInteger noWordIndex = [self.noWords indexOfObject:contentForThisRow];
        contentForThisRow2 = [self.enWords objectAtIndex:noWordIndex];
            NSLog (@"if success?");     
    }
        else 
    {
        contentForThisRow = [self.noWords objectAtIndex:row] ;
        contentForThisRow2 = [self.enWords objectAtIndex:row];
        NSLog (@"else success?");
    }
    
    static NSString *kCellID = @"cellID";

//standard code here etc for this method..

}

The codes above work perfectly except whenever I have used searchBar to filter and then click on Cancel button in the searchBar or Search button in the keyboard and then when I click on my custom "change" button in the navigationbar, the app crashes.

Before I use searchBar, there show up 4 NSLog after each change like:

• 2011-08-15 17:21:24.481 Enne1[4750:207] else success?
• 2011-08-15 17:21:24.483 Enne1[4750:207] else success?
• 2011-08-15 17:21:24.484 Enne1[4750:207] else success?
• 2011-08-15 17:21:24.485 Enne1[4750:207] else success?

And when I use searchBar to filter words, there show up also 4 NSLog like this:

• 2011-08-15 17:19:33.713 E1[4744:207] if success?
• 2011-08-15 17:19:33.714 E1[4744:207] if success?
• 2011-08-15 17:19:33.714 E1[4744:207] if success?
• 2011-08-15 17:19:33.715 E1[4744:207] if success?

But when after I have used searchBar and then cleared the searchText either with Cancel or Search and then click on "change button", there show up only 1 NSLog like this:
2

• 011-08-15 17:21:49.806 E1[4750:207] if success?

It should be

• else success

  in order to show the full lists, not

• if success

.

Am I missing something?

EDIT 15 august:
I have tried

if(mySearchBar.text.length > 0)

as well, but the tableview shows nothing when I clear my search string and there came up only 2 nslogs, that is:

• 2011-08-15 23:49:06.624 E1[5064:207] if success?
• 2011-08-15 23:49:06.626 E1[5064:207] if success?

By the way, why does it show up 4 nslogs each time I enter one alphabet in the search bar? Shouldnt it show only one nslog each time?

And my codes for textDidChange is:

 - (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchString
    
    {
NSLog (@" ss: %@", searchString);
        if ([searchString length] == 0) {
            [self performSelector:@selector(hideKeyboardWithSearchBar:) withObject:searchBar afterDelay:0];
            NSLog (@" searchstring: %@", searchString);
        }   
         [self filterContentForSearchText:searchString]; 
        [tableView reloadData];
        NSLog (@"has reloaded!");
        
        return;
    }

Edit 15 august; This is wrong: I suspect the code above is causing the app crashing? not reloading tableview properly?
Am I right? NSLog for searchString showed nothing…

2nd edit 15 august: I added NSLog (@" ss: %@", searchString); and of course it shows alphabet(s) each time I enter one alphabet. So it must be something wrong with mySearchBar.text > 0, how should I write this properly?

By the way, I added tableview and searchbar programmatically, tableviews delegate and datasource is linked to self and searchbars delegate is linked to self as well. There is nothing in InterfaceBuilder, only UIView.

Answer 1

Ah, I solved it by adding length to mySearchBar.text; mySearchBar.text.length > 0 works. I forgot to rewrite in another method, I changed mySearchBar.text to mySearchBar.text.length, that is:

- (NSInteger)tableView:(UITableView *)tableView1 numberOfRowsInSection:(NSInteger)section
{

    tableView1.rowHeight = 100 ;
    tableView1.separatorColor = [UIColor colorWithRed:0.40 green:0.70 blue:0.45 alpha:1.0];
    tableView1.opaque = NO;

    if (mySearchBar.text.length > 0)
    {
        return [self.filteredListContent count];
        NSLog (@"if return");
    }
    else
    {
        return [self.noWords count];
        NSLog (@"else return");
    }

}

@Daniel R Hicks
and
@ColdLogic: So both you are right that it is wrong to use only mySearchBar.text. Thank you very much for pointing me in the right direction.

But I still wonder why there come up 4 nslogs each time…

EDIT 16 august:

4 nslogs show up every time I launch the app, because there are 4 visible cells. My tableview.height is 100, so when I changed it to 50, 8 nslogs show up and as well as 8 visible cells.
