What is the *comment
parameter in:
NSString *NSLocalizedString(NSString *key, NSString *comment)
If I do this:
NSLocalizedString(@"Hello_World_Key", @"Hello World")
and have two versions of a Localizable.strings (English and Spanish), does each need the entry:
English.lproj/Localization.strings: @"Hello_World_Key" = @"Hello World";
Spanish.lproj/Localization.strings: @"Hello_World_Key" = @"Hola Mundo";
Isn't the English one redundant?
The second parameter is a comment that will automatically appear in the strings file if you use the genstrings command-line utility, which can create the strings file for you by scanning your source code.
The comment is useful for your localizers. For example:
NSLocalizedString(@"Save",@"Title of the Save button in the theme saving dialog");
When you run genstrings, this will produce an entry in the Localizable.strings file like this:
/* Title of the Save button in the theme saving dialog */
"Save" = "Save";
