A comma-separated list of arguments to substitute into format.
A string created by using format as a template into which the remaining argument values are substituted without any localization.
This method invokes initWithFormat:locale:arguments: without applying any localization. This is useful, for example, when working with fixed-format representations of information that is written out and read back in at a later time.
Returns an NSString object initialized by using a given format string as a template into which the remaining argument values are substituted according to given locale information. This method is meant to be called from within a variadic function, where the argument list will be available.
