cocoa - Model Key Path With Multiple Properties -

here, i'm using nsarraycontroller bind properties core data entities value of text view table cells.

what syntax use access multiple properties of entity in model key path?

example format string: @"%@, %@", lastname, firstname;

in bindings inspector text field:

1. select "value pattern: display pattern value1"
2. bind array controller
3. controller key = selection
4. model key path = lastname
5. display pattern = %{value1}@, %{value2}@
6. select available in bindings inspector: "display pattern value2"
7. bind value2 ac, selection, firstname

this documented in nstextfield section of cocoa bindings reference.

for completeness, here of own code sort of binding programmatically:

nsstring* bannerpattern = @": %{value1}@ items found, %{value2}@ hidden %{value3}@"; nsstring* totalpattern = [datestring stringbyappendingstring:bannerpattern];  [ftview.textfield bind:@"displaypatternvalue1" toobject:ft withkeypath:@"visiblenumber" options:@{nsdisplaypatternbindingoption : totalpattern}]; [ftview.textfield bind:@"displaypatternvalue2" toobject:ft withkeypath:@"hiddennumber" options:@{nsdisplaypatternbindingoption : totalpattern}]; [ftview.textfield bind:@"displaypatternvalue3" toobject:ft withkeypath:@"newstring" options:@{nsdisplaypatternbindingoption : totalpattern}];
