iOS漢字轉拼音

寫了一個類方法，傳漢字返回拼音，如果需要返回的拼音不帶空格，將註釋打開即可。

#import <Foundation/Foundation.h>

@interface NSString (TransferToPinyin)

+(NSString*)transerToPin:(NSString*)hanzi;

@end

#import "NSString+TransferToPinyin.h"

@implementation NSString (TransferToPinyin)

+(NSString*)transerToPin:(NSString*)hanzi{

   CFMutableStringRef string =CFStringCreateMutableCopy(NULL,0, (__bridgeCFStringRef)hanzi);

    CFStringTransform(string,NULL,kCFStringTransformMandarinLatin, NO);

    CFStringTransform(string,NULL,kCFStringTransformStripDiacritics, NO);

   NSString *pinyin = (__bridgeNSString *)(string);

//    NSString *s = [str stringByReplacingOccurrencesOfString:@" " withString:@""];//去空格（如果需要）

   return pinyin;

}

@end
