emjio表情转json

今天碰到了上传文字给服务端的时候emjio表情转成json就不对了

有大神帮忙解决了，记笔记记笔记---

#import "NSString+EncodedString.h"

@implementation NSString (EncodedString)

+(NSString *)decodeString:(NSString*)encodedString

{

//NSString *decodedString = [encodedString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding ];

NSString *decodedString  = (__bridge_transfer NSString *)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL,

(__bridge CFStringRef)encodedString,

CFSTR(""),

CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));

return decodedString;

}

+(NSString*)encodeString:(NSString*)unencodedString{

// CharactersToBeEscaped = @":/?&=;+!@#$()~',*";

// CharactersToLeaveUnescaped = @"[].";

NSString *encodedString = (NSString *)

CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,

(CFStringRef)unencodedString,

NULL,

(CFStringRef)@"!*'();:@&=+$,/?%#[]",

kCFStringEncodingUTF8));

return encodedString;

}

@end

//从json转时

+(NSString *)decodeString:(NSString*)encodedString;

//转json时

+(NSString*)encodeString:(NSString*)unencodedString;

主要是换了编码方式
