byte[]utf8Bytes=str.getBytes("UTF-8"); 1. 这行代码使用getBytes()方法将字符串str编码为UTF-8格式的字节数组。编码格式参数被设置为"UTF-8"。 步骤3: Stringutf8Str=newString(utf8Bytes,"UTF-8"); 1. 这行代码使用String的构造函数将UTF-8格式的字节数组utf8Bytes解码为字符串utf8Str。同样,编码格...
const char* cstr = CFStringGetCStringPtr( cfstr, kCFStringEncodingUTF8 );以上代码在cfstr是英语字符情况下可以,一碰到中文就转换失败,返回的cstr为NULL.在中文情况下,我试着用NSString进行转换,可以转换成功,代码如下:CFStringRef cfstr;...NSString* nstr = (NSString*)cfstr;const char* cstr = [nstr c...
intmain(){char source[] = "Hello, world!";char* destination = source;strcpy(destination, source); // Copy the source string to the destination stringprintf("Source: %s\n", source);printf("Destination: %s\n", destination);return;} 事实上，这样也未尝不可。只不过现在 destination 变成了 ch...
