I have a tableView which will accept one new row and updates to that row
succeed. Subsequent application of the same process does add new rowData
dictionary objects to the tableData model (NSMutableArray) but the tableView
will not display these additions.
A button on the UI is wired up to - (IBAction) addTableItem:(id)sender; and
pops in the first row just fine. NSLog() messages have revealed that additional
clicks on the button add new rows to the tableData array, but the UI does not
respond to these events.
I'm pretty sure I'm missing something pretty basic here.
@interface MyClass : NSViewController < NSTableViewDataSource,
NSTableViewDelegate >
@property (retain) IBOutlet NSTableView * tableView;
@property (retain) IBOutlet NSMutableArray * tableData;
- (IBAction) addTableItem:(id)sender;
@end
@implementation MyClass
@synthesize tableView;
@synthesize tableData;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
tableData = [NSMutableArray array];
}
return self;
}
- (NSInteger) numberOfRowsInTableView:(NSTableView *)tableView {
return [tableData count] || 0;
}
- (id) tableView:(NSTableView *)tableView
objectValueForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row {
NSDictionary * rowData = [tableData objectAtIndex:row];
return [rowData valueForKey:[tableColumn identifier]];
}
- (void)tableView:(NSTableView *)aTableView setObjectValue:(id)anObject
forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex {
NSMutableDictionary * rowData = [[tableData objectAtIndex:rowIndex]
mutableCopy];
[rowData setValue:anObject forKey:[aTableColumn identifier]];
[tableData replaceObjectAtIndex:rowIndex withObject:rowData];
[tableView reloadData];
}
- (IBAction) addTableItem:(id)sender {
[tableData addObject:[NSDictionary
dictionaryWithObjectsAndKeys:@"prop",@"property",@"val",@"value",nil]];
[tableView reloadData];
}
@end

Consistently place constants on the LHS of an expression: you cannot
accidentally assign when you meant to compare.
