首先参考了这片文章http://blog.csdn.net/xueer8835/article/details/7955590
把库里的zbar/qrcode/qrdectxt.c 文件的
//latin1_cd=iconv_open("UTF-8","ISO8859-1");
变成
latin1_cd=iconv_open("UTF-8","GB18030")
然后再重新编译.a文件
最后在zarbar回调中加上代码
ZBarSymbol *sym = nil;
for(sym in syms) {
break;
}
NSString *result = sym.data;
if ([result canBeConvertedToEncoding:NSShiftJISStringEncoding])
{
result = [NSString stringWithCString:[result cStringUsingEncoding: NSShiftJISStringEncoding] encoding:NSUTF8StringEncoding];
}
