很多时候需要将c,c++形式的struct转换为
NSData来处理。但是怎么转换呢?
假设有这么一个结构体:
struct MYINFO
{
int a;
long b;
char c;
};
struct MYINFO
infoStruct;
infoStruct.a = 100;
infoStruct.b =10000;
infoStruct.c = ‘c‘;
1. 将
infoStruct转换为NSData
NSData * msgData =
[[NSData alloc]initWithBytes:&infoStruct
length:sizeof(infoStruct)];
2. 将 msgData转换为
MYINFO 对象。
struct MYINFO
infoStruct2;
[msgData
getBytes:&infoStruct2 length:sizeof(infoStruct2)];
