IOS-how to return the pinyin mnemonic code of a string, ios-pinyin

I also modified the sample code on the Internet based on it. Because projects will be used, I believe many people will also use projects. After implementation, we will share it with you, hoping that it will not take time for later users.

Tip: the regular expression is used here, and a third-party open-source component: RegexKitLite (how to use this component is a lot of online tutorials)

 

# Pragma mark-get the first letter of Pinyin (input Chinese character string, return the first letter of lowercase pinyin)

+ (NSString *) pinYingFirstCharactorStr :( NSString *) aString

{

// Converted to a variable string

NSMutableString * str = [NSMutableString stringWithString: aString];

// First convert to PinYin with tones

CFStringTransform (CFMutableStringRef) str, NULL, kCFStringTransformMandarinLatin, NO );

// Convert to PinYin without tone

CFStringTransform (CFMutableStringRef) str, NULL, kCFStringTransformStripDiacritics, NO );

// Convert to lowercase pinyin

NSString * pinYin = [str lowercaseString];

// Converts a pinyin string to an array of substrings Based on the specified regular expression.

NSString * regexString = @ "\ s"; // The regular symbol of the split interval used is a space.

NSArray * aArray = [pinYin componentsSeparatedByRegex: regexString]; // split

// Traverse the string array and splice the first letter

NSString * strReturn;

NSString * strProc = @"";

For (int I = 0; I <aArray. count; I ++ ){

// Numbers may be processed for substrings.

NSString * strTmp = [CRGOtherHelper firstReplaceInNumberStr: aArray [I];

StrReturn = [strProc stringByAppendingString: strTmp];

StrProc = strReturn;

}

// Obtain and return the first letter

Return strReturn;

}

 

// Split the input string into a new sub-array by numerical interval. The non-empty members in the sub-array are given the first letter to obtain a temporary character.

// Use this temporary character to replace the corresponding part of the character string in the original array member (the search method is to compare the previously split Member)

+ (NSString *) firstReplaceInNumberStr :( NSString *) waitProcStr

{

NSString * strResult = nil;

NSString * strWait = [[waitProcStr copy] autorelease];

// Find a string

NSString * regexString = @ "[0-9]";

 

// Further split into substrings Array

NSArray * strArray = [waitProcStr componentsSeparatedByRegex: regexString]; // split

NSArray * strCopy = [strArray copy];

For (int j = 0; j <strArray. count; j ++ ){

If (! [(NSString *) strArray [j] isEqualToString: @ ""])

{

// First letter

NSString * fistChar = [strArray [j] substringToIndex: 1];

// Partially replace

StrResult = [strWait stringByReplacingOccurrencesOfRegex: strCopy [j] withString: fistChar];

StrWait = strResult;

}

}

Return strResult;

}

Hope everyone can use it!
