IPhone xml 文件GBK 转 UTF8

iphone不支持GBK,需要转化,方法如下:

[cpp] view plain copy

1. -(NSData *) toUtf8:(NSData *)inData {  
2.     CFStringRef gbkStr = CFStringCreateWithBytes(NULL, [inData bytes], [inData length], kCFStringEncodingGB_18030_2000, false);  
3.       
4.     if (NULL == gbkStr) {  
5.         return nil;  
6.     } else {  
7.         NSString *gbkStrTmp = (NSString *)gbkStr;  
8.         NSString *utf8NSString = [gbkStrTmp stringByReplacingOccurrencesOfString:@"l version=/"1.0/" encoding=/"gbk/""  
9.                                                                       withString:@"l version=/"1.0/" encoding=/"UTF-8/""];  
10.           
11.         return [utf8NSString dataUsingEncoding:NSUTF8StringEncoding];                             
12.     }                                     
13. }
