iOS汉字转拼音

写了一个类方法，传汉字返回拼音，如果需要返回的拼音不带空格，将注释打开即可。

#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
