    <p>I have an action for searching in NSMutableArray with name searcharray, which is equal to array with which NSTableView are connected.And I wrote a method for adding items to TableView just by sending NSMutableArray to my method. The problem is that after searching if I delete what I have typed in SearchField and SearchField is empty, the compiler doesn't feel that it's empty and my TableView getting empty too, but due my code it's have to be with data from searcharray. Here is my code:</p> <pre><code>#import "myTableViewAppDelegate.h" @implementation myTableViewAppDelegate @synthesize window; @synthesize searcharray; -(void)addItems:(NSMutableArray *)ar{ array = ar; [array retain]; [tableView reloadData]; } - (int)numberOfRowsInTableView:(NSTableView *)tableView{ return (int)[array count]; } - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row { return [array objectAtIndex:row]; } - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { // Insert code here to initialize your application NSMutableArray *animals = [[NSMutableArray arrayWithObjects:@"Cat", @"Dog", @"Fish", @"Squirrel", @"Bear", @"Turtle", nil] retain]; NSLog(@"%@",animals); searcharray = animals; [self addItems:animals]; } - (IBAction)search:(id)sender { //NSLog(@"%@",searcharray); NSString *filter = [[NSString alloc] initWithString:[search stringValue]]; NSMutableArray *result = [[NSMutableArray alloc] init]; if (filter != nil) { for (NSString *item in searcharray) { if ([item rangeOfString:[search stringValue]].location !=NSNotFound ) { NSLog(@"Item %@ contains %@",item,[search stringValue]); [result addObject:item]; } } } else{ result = searcharray; } NSLog(@"%@",result); [self addItems:result]; [result release]; [filter release]; } @end </code></pre>

    1. COWell, just magic dance with tambourine around the computer so far :) But, yeah , I have played with blocks if and else, checked all variables while app is running and everything looks completely fine to me. I have no idea why it doesn't work and tableview is empty :(

    2. COI used similar routine in C# before and that worked there. I'm new to Objective-C, so maybe there is some stuff which I don't know yet.

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.
