TableView Search Question : SIGBART ERROR

richammond · October 2011

Hi,

Having a bit of trouble with a specific piece of code. I can implement the UISearch which works well but when there's a character contained in several fields, i get an index out of bounds error. Here's what i mean :

I've got a table with the following fields and some dummy data as follows :

------------
id | word | keywords| definition
1 | w1 | wessai, testing | trying something
2 | d2 | work, code | cloloured work
------------

The current tableview displays the items in its row as follows
w1 (cell.textLabel.text)
essai,testing (cell.detailTextLabel.text)

Up to here, everything's FINE. When i do the search, i can find what i want, so if i type "o", i'll see :
d2
work, code
Which is fine. But when i type "w" i get a sigbart error, with an index out of bounds :-(

Here's what I'm trying to achieve :
Search through word AND keywords AND definition at the same time

And here's my code which handles the search term and puts it in an array:


- (void)handleSearchForTerm:(NSString *)searchTerm
{
	
	[self setSavedSearchTerm:searchTerm];
	
	if ([self searchResults] == nil)
	{
		NSMutableArray *array = [[NSMutableArray alloc] init];
		[self setSearchResults:array];
		[array release], array = nil;
	}
	
	[[self searchResults] removeAllObjects];
    
    //test begin
    if ([self searchResults_2] == nil)
	{
		NSMutableArray *array = [[NSMutableArray alloc] init];
		[self setSearchResults_2:array];
		[array release], array = nil;
	}
	
	[[self searchResults_2] removeAllObjects];
    //test end
    
	
	if ([[self savedSearchTerm] length] != 0)
	{
		for (NSString *currentString in glossaryListItems_2)
		{
			if ([currentString rangeOfString:searchTerm options:NSCaseInsensitiveSearch].location != NSNotFound)
			{
				[[self searchResults] addObject:currentString];  //add words to search results array
			}
		}
        
        for (NSString *currentString in glossaryKeywords)
		{
			if ([currentString rangeOfString:searchTerm options:NSCaseInsensitiveSearch].location != NSNotFound)
			{
				[[self searchResults_2] addObject:currentString]; //add keywords to search results 2 array
			}
		}
	}
    
}

Here's what inside my

- (UITableViewCell *)tableView:(UITableView *)tableView
		 cellForRowAtIndexPath:(NSIndexPath *)indexPath
{


	if (tableView == [[self searchDisplayController] searchResultsTableView]){
        
        cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
        
        //test 
        NSString *searchedValue;
        NSString *searchedValue_2;
        if ([searchResults count] != 0) {
            @try {
                searchedValue = [searchResults objectAtIndex:indexPath.row]; //typed value
            }
            @catch (NSException* ex) {
                NSLog(@\"exception catched on SR1: %@\",ex);
                searchedValue = [searchResults objectAtIndex:0];
            }
             
            
        }
        
        if ([searchResults_2 count] != 0) {
            @try {
                searchedValue_2 = [searchResults_2 objectAtIndex:indexPath.row]; //typed value
            }
            @catch (NSException* ex) {
                NSLog(@\"exception catched on SR2: %@\",ex);
                searchedValue_2 = [searchResults objectAtIndex:0];
            }  
        }
        //test end
        

       
                
        //let's retrieve short description from DB - begin
        sqlite3 *db;
        int dbrc; // database return code
        ikoi_2AppDelegate *appDelegate = (ikoi_2AppDelegate*)
        [UIApplication sharedApplication].delegate;
        const char* dbFilePathUTF8 = [appDelegate.dbFilePath UTF8String];
        dbrc = sqlite3_open (dbFilePathUTF8, &db);
        if (dbrc) {NSLog (@\"couldn't open db:\");}
        sqlite3_stmt *dbps;
        
        NSString *queryStatementNS;
        
        if (([searchResults count] == 0) && [searchResults_2 count] != 0){
        queryStatementNS = [NSString stringWithFormat:@\"SELECT * FROM glossary WHERE keywords LIKE \\"%@\\"\",searchedValue_2];
        }else if (([searchResults count] != 0) && [searchResults_2 count] == 0) {
        queryStatementNS = [NSString stringWithFormat:@\"SELECT * FROM glossary WHERE word LIKE \\"%@\\"\",searchedValue];   
        }else if (([searchResults count] != 0) && [searchResults_2 count] != 0) {
        queryStatementNS = [NSString stringWithFormat:@\"SELECT * FROM glossary WHERE word LIKE \\"%@\\" OR keywords LIKE \\"%@\\"\",searchedValue,searchedValue_2];
        }

        
        const char *queryStatement = [queryStatementNS UTF8String];
        sqlite3_prepare_v2 (db, queryStatement, -1, &dbps, NULL);
        NSLog(@\"query : %@\",queryStatementNS);
        
        while (sqlite3_step (dbps) == SQLITE_ROW) {
        NSString *db_word = [[NSString alloc] initWithUTF8String: (char*) sqlite3_column_text (dbps,1)];
        NSString *db_keywords = [[NSString alloc] initWithUTF8String: (char*) sqlite3_column_text (dbps, 2)];
            
            cell.textLabel.text = db_word;
            cell.detailTextLabel.text = [NSString stringWithFormat:@\"Synonyms : %@\",db_keywords];               
        
            [db_word release];
            [db_keywords release];

        }
        
        
        sqlite3_finalize (dbps);
        sqlite3_close(db);
        //let's retrieve short description from db - end
      
        
    }

Any help will be greatly appreciated
