How to get an array of sentences using CFStringTokenizer?

由 落爺英雄遲暮 提交于 2020-01-20 02:44:35
问题 I've created an string tokenizer like this: stringTokenizer = CFStringTokenizerCreate( NULL , (CFStringRef)str , CFRangeMake(0, [str length]) , kCFStringTokenizerUnitSentence , userLocale); But how do I obtain those sentences now from the tokenizer? The CF String Programming Guide doesn't mention CFStringTokenizer or tokens (did a full-text search in the PDF). 回答1: Here is an example of CFStringTokenizer usage: CFStringRef string; // Get string from somewhere CFLocaleRef locale =

How do I print a CFStringRef in a DTrace action?

由 五迷三道 提交于 2019-12-12 07:53:33
问题 I have a DTrace probe catching calls to a function, and one of the function's arguments is a CFStringRef . This is private structure that holds a pointer to a unicode string. But the CFStringRef is not itself a char* , so normal DTrace methods like copyinstr() just return ?cp? , which isn't exactly helpful. So how can I print out the string in the DTrace action? 回答1: As far as I know, there is not built-in support for this kind of thing. Usually a library would publish a probe that decodes

NSData encoding

由 梦想与她 提交于 2019-12-12 06:10:02
问题 Currently, I'm trying to parse an NSData in my iOS app. Problem is, I can't seem to find a proper hebrew encoding for parsing.

The closest I've got to solving the issue was using CFStringConvertEncodingToNSStringEncoding(CFStringEncodings.ISOLatinHebrew) yet it throws 'CFStringEncodings' is not convertible to 'CFStringEncoding' (notice Encoding s vs
