macOS Core data - binding related problem in NSNumberFormatter and NSDatePicker

Hi all,

I am trying a core-data sample application, from Cocoa Programming - Aaron Hillegass.

In it there is an entity Car, with following properties:

1. condition - Int 16
2. datePurchased - Date
3. makeModel - String
4. onSpecial - Boolean
5. photo - Binary
6. price - Decimal

There are certain view objects such as-

1. TableView
2. DatePicker
3. Image Well, etc.

Some of the bindings performed are-

1. TableView -> TableColumn with NSNumberFormatter (set as currency)-> value: arrangedObjects.price
2. DatePicker -> value: selection.datePurchased

Problems are:

1. In TableColumn with NSNumberFormatter it is not accepting any decimal numbers which I am entering for currency, such as - 123,00 or 123.45 or +235 or 567. It is always displaying this alert message: Formatting error.

2. Whenever I am selecting a row in table and changing its corresponding value in date picker, it is simultaneously changing the values for other records, ie. if for first row in table I have set it to 12/25/2004, it is keeping it 12/25/2004 for other rows.

Can anyone help me to resolve my problems? The source code can be found here

Thanks,

Monaj

Hi JoshDC, thanx for your reply

Regarding:

1. It wants a currency symbol as well as a number. Ticking the lenient checkbox seems to fix this.

Can you tell me where can I find the lenient check box? I tried to search it in IB for NumberFormatter but was unable to find it.

Thanks,

Set the behaviour to Mac OS X 10.4+ Default, style to currency and there should be a Lenient checkbox next to the Localize one.

Hi JoshDC,

Once again thanks for your reply, but still unable to find lenient check box

I am posting the image of Inspector -> attributes property, so that you can help me to find it:



Thanks,

2. It's not changing the date, just that any new objects don't have a date to change to (and therefore the bound date picker doesn't change).

Your interpretation is correct, when I set the default value of datePurchased attribute to some value say- 2010-12-10 in MyDocument.xcdatamodel, it started working as intended

So I am now thinking that can we set default value to today's date in xcdatamodel ?

Thanks,

Monaj
