int main(int argc, const char * argv[])
{
@autoreleasepool {
NSString * str = @"Hello World!";
NSData * data = ;
//将字符串str进行UTF8编码后存储文件"data"
NSLog(@"%s",data.bytes);
//输出文件字符
NSString * newData = [ initWithData:data encoding:NSUTF8StringEncoding];
//将data中的字符进行UTF8编码后，存进字符串"newData";
NSLog(@"%@",newData);
}
return 0;
}
输出结果为：
2014-01-10 21:48:04.711 NSData Hello World!
2014-01-10 21:48:04.713 NSData Hello World!
