Hi,
is the 10.0+ style of NSNumberFormatter no longer supported? I
recently moved from developing in Xcode3 under OS X 10.7 to Xcode 4 under OS X
10.8, and from having a Base SDK of 10.6 to 10.7, and from a Deployment Target
of 10.5 to 10.6, and am now having problems with my xib-base NSTextFields
connected to an NSNumberFormatter. The formatter uses the 10.0+ style,
allowing me to set the "Zero" field, which I am setting to the string N/A.
This worked fine, even when running in 10.8 or 10.9, but crashes now that I've
compiled under these new conditions.
Here is the call stack when the exception is thrown:
2014-05-07 08:32:15.225 Cubase 7.5[947:707] -[__NSCFString string]:

...
I am simply calling setIntValue with a value of 0, which in previous builds
would set the text field's text to "N/A". But now this exception is thrown,
and I don't know why or what to do about it. If the 10.0 style of
NSNumberFormatter is no longer supported, why is it still available in Xcode 4,
and why does it compile and run, up to the point I set its value to 0?
Thanks,
-Howard
