I am trying to generate an NSDictonary that can be used to populate a listview with data I retrieved from an SQL statement. when I go to create an array and add them it adds the arrays for ALL my keys and not just for the current key. I've tried a removeAllObjects on the array but for some reason that destroys ALL my data that I already put in the dictionary.
//open the database
if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK)
{
const char *sql = "select alphaID, word from words order by word";
sqlite3_stmt *selectStatement;
//prepare the select statement
int returnValue = sqlite3_prepare_v2(database, sql, -1, &selectStatement, NULL);
if(returnValue == SQLITE_OK)
{
NSMutableArray *NameArray = [[NSMutableArray alloc] init];
NSString *alphaTemp = [[NSString alloc] init];
//loop all the rows returned by the query.
while(sqlite3_step(selectStatement) == SQLITE_ROW)
{
NSString *currentAlpha = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 1)];
NSString *definitionName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 2)];
if (alphaTemp == nil){
alphaTemp = currentAlpha;
}
if ([alphaTemp isEqualToString:(NSString *)currentAlpha]) {
[NameArray addObject:definitionName];
}
else if (alphaTemp != (NSString *)currentAlpha) {
[self.words setObject:NameArray forKey:currentAlpha];
[NameArray removeAllObjects];
[NameArray addObject:definitionName];
}
}
}
The Statement above adds all the "keys" but then removes all the array elements for all keys. if I take out the removeAllKeys it adds ALL the array elements for ALL keys. I don't want this I want it to add the array elements FOR the specific key then move on to the next key.
in the end I want a NSDictonary with
A (array)
Alpha (string)
Apple (string)
B (array)
Beta (string)
Ball (string)
C (array)
Code (string)
...
