CFStringTokenizerCreate(_:_:_:_:_:)

Declaration

func CFStringTokenizerCreate(_ alloc: CFAllocator!, _ string: CFString!, _ range: CFRange, _ options: CFOptionFlags, _ locale: CFLocale!) -> CFStringTokenizer!

Parameters

alloc

The allocator to use to allocate memory for the new object. Pass NULL or kCFAllocatorDefault to use the current default allocator.

string

The string to tokenize.

range

The range of the characters in string to tokenize.

options

A tokenization unit option that specifies how string should be tokenized. The options can be modified by adding unit modifier options to tell the tokenizer to prepare specified attributes when it tokenizes string.

For possible values, see Tokenization Modifiers.

locale

A locale that specifies language- or region-specific behavior for the tokenization. You can pass NULL to use the default system locale, although this is typically not recommended—instead use CFLocaleCopyCurrent() to specify the locale of the current user.
