    text
    copied!<p>I'm fairly new to obj-c and cocoa so please bear with me:</p> <p>I have a NSTableView set up with cocoa bindings which works as expected with the simple -add -remove, etc methods provided by an instance of NSArrayController in my nib. I would like to programmatically add objects to the array that provides content for this controller (and hence for the table view) and then update the view accordingly.</p> <p>I current have a working method for adding a new object to the array (verified by NSLog) but I can't figure out how to update the table view.</p> <p>So: <strong>How do I update the bound tableview?</strong> (ie, after I have programmatically added objects to my array). <strong>I'm essentially after some view refreshing code like [view reloadData] in glue code, but I want it to work with the bindings I have in place.</strong></p> <p>Or is there a KVC/KVO related solution to this problem?</p> <p>Code Details: AppController.h</p> <pre><code>@interface AppController : NSObject @property NSMutableArray *clientsArray; -(IBAction)addClientFooFooey:(id)sender; @end </code></pre> <p>AppController.m (note, I also have the appropriate init method not shown here)</p> <pre><code>@implementation AppController ... -(IBAction)addClientFooFooey:(id)sender{ [self.clientsArray addObject:[[Client alloc] initWithFirstName: @"Foo" andLastName:@"Fooey"]]; //Need some code to update NSTableView here } @end </code></pre> <p>Client.h just simply defines two properties: firstName and lastName. The 2 columns of an NSTableView in my mainmenu.nib file are appropriately bound to these properties via an array controller bound to my AppController instance.</p> <p>On a side note/as an alternative. How could I add functionality to the existing NSArrayController method -add, ie, something like: -addWithFirstName:andLastName and still have this compatible with bindings?</p>
