Body
In the function fetchDataForTierOne, first line myTierOneDict = [[NSMutableDictionary alloc]init]; is creating memory leak. You are creating a dictionary and assigned a different dictionary returned by getDataToDisplayTierOne function. So, the dictionary created in the first line of function fetchDataForTierOne will become unreferenced and will create a leak. No need to write first line. Second, return the dictionary with autorelease and retain it in fetchDataForTierOne function. After completing the usage release it. Updated Code: //=============================================================== -( NSMutableDictionary * ) getDataToDisplayTierOne:(NSString*)dbPath{ //================================================================ <pre><code>NSMutableDictionary *aTierOneData = [[NSMutableDictionary alloc]init]; if (sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) { const char *sql_query_stmt = "select * from main_categories"; sqlite3_stmt *selectstmt; if(sqlite3_prepare_v2(database, sql_query_stmt, -1, &selectstmt, NULL) == SQLITE_OK) { while(sqlite3_step(selectstmt) == SQLITE_ROW) { NSString *aValue = [[NSString alloc] initWithUTF8String: (const char *) sqlite3_column_text(selectstmt, 1)]; NSString *aId = [[NSString alloc] initWithUTF8String: (const char *) sqlite3_column_text(selectstmt, 0)]; [aTierOneData setObject:aId forKey:aValue]; [aValue release]; [aId release]; } } } else{//Even though the open call failed, close the database connection to sqlite3_close(database); } return [aTierOneData autorelease]; </code></pre> } -(void)fetchDataForTierOne{ //=========================== <pre><code>myTierOneDict = [[myDBOperations getDataToDisplayTierOne:[appDelegate getDBPath]]retain]; NSArray *myTierOneDictKeys = [myTierOneDict allKeys]; myTierOneData = [[NSMutableArray alloc] initWithArray:(NSArray*)myTierOneDictKeys]; if ([myTierOneData count] > 0 ){ [self constructTierOnePicker]; } </code></pre> [myTierOneDict release]; }

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
