if(returnValue == SQLITE_OK)
{
//loop all the rows returned by the query.
while(sqlite3_step(selectStatement) == SQLITE_ROW)
{
//int key = sqlite3_column_int(selectStatement, 0);
NSString *Term = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 2)];
Container *myObject=[[Container alloc] InitWithTermId:Term];
[self.pickerArray addObject:myObject];

Here's a possible error:
NSString *Term = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 2)];
Container *myObject=[[Container alloc] InitWithTermId:Term];
[self.pickerArray addObject:myObject];
[myObject release];
You're adding Container objects to the array.
- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return [localArray objectAtIndex:row];
}
Then you return a Container object when you're expected to return an NSString.
