    1. COThank you Steven. I am not using NSUserDefaults. However, I wonder if my last comment to Brad's response makes sense. I believe that I may have been getting away with something that I should have not been allowed to do. Namely, the releasing of the NSMutableArray and then filling it again with each search. I will put some code in my next comment. (I'm almost out of space in this block of text.)

    2. CO// Used to do a release here: [list removeAllObjects]; while(sqlite3_step(statement) == SQLITE_ROW && (limit == NO || [list count] <= INITSEARCHROWS)) { NSMutableArray *columns = [[NSMutableArray alloc] init]; for(int i = 0; i < 7; i++) { NSString *value; char *column = (char *)sqlite3_column_text(statement, i); if (column == nil) { value = [[NSString alloc] initWithUTF8String:""]; } else { value = [[NSString alloc] initWithUTF8String:column]; } [columns addObject:value]; [value release]; } [list addObject:columns]; [columns release]; } [sql closeDatabase]; [sql dealloc]; }

    3. COOK. Most of this looks OK. I do have a question on who owns the memory from the "sqlite3_column_text(statement, i);" call. Likewise, the [[NSMutableArray alloc] init] really should be [[NSMutableArray alloc] initWithCapacity:8]. The NSMutableArray did NOT override init, there is a chance some code is not being called that really should be. Also, use the convenience methods of "arrayWithCapacity:", "stringWithUTF8String:". They will remove lots of releases from your code and make your life easier.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
