[Recommended] third-party library for converting iOS Chinese characters to pinyin, and third-party library for ios Chinese characters to PinYin

PinYin4Objc is an open-source git Chinese character-to-pinyin library that supports simplified and traditional Chinese characters. Efficiency other libraries such as POAPinyin should be high. The conversion library is also described below.

 

　　Implementation Principle

Use unicode_to_hanyu_pinyin.txt to store the pinyin corresponding to the Chinese character encoding and load it into the memory in a dictionary.

 NSString *resourceName =[[NSBundle mainBundle] pathForResource:@"unicode_to_hanyu_pinyin" ofType:@"txt"];        NSString *dictionaryText=[NSString stringWithContentsOfFile:resourceName encoding:NSUTF8StringEncoding error:nil];        NSArray *lines = [dictionaryText componentsSeparatedByString:@"\r\n"];        __block NSMutableDictionary *tempMap=[[NSMutableDictionary alloc] init];        @autoreleasepool {                [lines enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {                    NSArray *lineComponents=[obj componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];                    [tempMap setObject:lineComponents[1] forKey:lineComponents[0]];                }];         }        self->_unicodeToHanyuPinyinTable=tempMap;        [self cacheObjec:self->_unicodeToHanyuPinyinTable forKey:kCacheKeyForUnicode2Pinyin];

 

 

After entering a Chinese character, we can get the encoding of the Chinese character. The following figure is used as an example. When we click OK

NSString * mainPinyinStrOfChar = [PinyinHelper getFirstHanyuPinyinStringWithChar: [str characterAtIndex: I] withHanyuPinyinOutputFormat: outputFormat]; generate Chinese characters in a loop

The value of "8F6C" in the dictionary is

The first one in the array is pinyin...

 

　　Use

1. Download the library

 

2. Introduce the header file # import "PinYin4Objc. h"

 

3. Create a pinyin character format

HanyuPinyinOutputFormat * outputFormat = [[HanyuPinyinOutputFormat alloc] init];

The format includes ToneType, CharType, and CaseType.

Typedef enum {ToneTypeWithToneNumber, // has a tone number, such as PIN1 ToneTypeWithoutTone, // has no tone ToneTypeWithToneMark} ToneType;

Typedef enum {CaseTypeUppercase, // pinyin size CaseTypeLowercase // pinyin lowercase} CaseType;

typedef enum {    VCharTypeWithUAndColon,    VCharTypeWithV,    VCharTypeWithUUnicode}VCharType;

 

 

4. Set the format

[OutputFormat setToneType: ToneTypeWithoutTone];

[OutputFormat setVCharType: VCharTypeWithV];

[OutputFormat setCaseType: CaseTypeLowercase];

 

5. Call toHanyuPinyinStringWithNSString: withHanyuPinyinOutputFormat: withNSString: outputBlock for conversion.

[PinyinHelper toHanyuPinyinStringWithNSString:sourceText withHanyuPinyinOutputFormat:outputFormat withNSString:@" " outputBlock:^(NSString *pinYin) {      _outputTv.text=pinYin;  }];
