Disable Regional settings for NSTextField

I have a problem with NSTextField in Cocoa. Is there a way to remove regional settings from a NSTextField

I want the user to only enter values like so 0.6, 0.7 but if the u开发者_如何学JAVAser is not from US he is forced to enter like this 0,6, 0,7

So if the user is not US user if he enters 0.7 [textField floatValue] will return 0 and if the user is US and he enters 0,7 [textField floatValue] will return 0

Well lets say that is something i can accept but then i want to format the value and display it only with 3 decimals

this will work for US but will not work for non US even though value is a correct float (eg 0.3) [textField setStringValue:[NSString stringWithFormat:@"%.3f",value]];

textfield is of type NSTextField

Thank you!

You should be using NSNumberFormatter instead of +[NSString stringWithFormat:]. In fact, using NSNumberFormatter allows you to:

• Configure the minimum and maximum number of digits after the decimal separator;
• Configure the string that’s used as the decimal separator in case you want to override the user’s locale;
• Configure the rounding behaviour, if that’s important;

amongst other features.

If your NSTextField is in a nib file, Interface Builder/Xcode 4 allows you to link the formatter outlet to an NSNumberFormatter instance. You can also do it programatically by sending -setFormatter: to the text field.
