Type Method

stringWithFormat:

Returns a string created by using a given format string as a template into which the remaining argument values are substituted.

Declaration

+ (instancetype)stringWithFormat:(NSString *)format, ...;

Parameters

format: A format string. See Formatting String Objects for examples of how to use this method, and String Format Specifiers for a list of format specifiers. This value must not be nil.
Important
Raises an NSInvalidArgumentException if format is nil.
...: A comma-separated list of arguments to substitute into format.

Return Value

A string created by using format as a template into which the remaining argument values are substituted without any localization.

Discussion

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.
