{
int strlength = 0;
char* p = (char*) [strtemp cstringusingencoding:nsunicodestringencoding];
for (int i=0; i<[strtemp lengthofbytesusingencoding:nsunicodestringencoding]; i++) {
if (*p) {
p++;
strlength++;
}
else {
p++;
}
}
return strlength;
}
To get the Chinese and English mixed string length method 2
