字节数组。 ObjC Swift
BytesArray. ObjC to Swift
我正在尝试编写 Swift 以下 ObjC(头文件)代码的实现。
#include <stddef.h>
#ifndef VO_CERTIFICATE_TYPE
#define VO_CERTIFICATE_TYPE
typedef struct _voCertificate
{
const char* bytes;
size_t length;
}
voCertificate;
#endif
static const char myCertificate_BYTES[] =
{
103, 92, -99, 33, 72, 48, 119, -72,
-77, 75, -88, 81, 113, -46, -119, -119,
5, 42, -33, 94, 23, 3, -112, 34,
-63, 75, -77, 26, -41, -69, 50, 71,
19, 121, 109, -60, 40, 18, 46, -86,
..........
};
voCertificate const myCertificate =
{
myCertificate_BYTES,
sizeof(myCertificate_BYTES)
};
//////////////////////////////////////
NSData *certificate = [NSData dataWithBytes:myCertificate.bytes length:myCertificate.length];
我最好的假设是:
let myCertificate = [
103, 92, -99, 33, 72, 48, 119, -72,
-77, 75, -88, 81, 113, -46, -119, -119,
5, 42, -33, 94, 23, 3, -112, 34,
-63, 75, -77, 26, -41, -69, 50, 71,
19, 121, 109, -60, 40, 18, 46, -86,
........................]
var certificate = NSData(bytes: myCertificate as [Byte], length: myCertificate.count)
我也尝试通过 Bridging-Header 访问 ObjC 变量,但是出现 "Undefined symbols for architecture armv7" 错误。
如果有任何帮助,我将不胜感激。
你最大的问题是你的 myCertificate 数组的类型是 Int 而不是 Int8。这是对我有用的东西。请注意,我从 NSData 对象重建数组以查看是否一切正常。
let myCertificate = Array<Int8>(arrayLiteral:
103, 92, -99, 33, 72, 48, 119, -72,
-77, 75, -88, 81, 113, -46, -119, -119,
5, 42, -33, 94, 23, 3, -112, 34,
-63, 75, -77, 26, -41, -69, 50, 71,
19, 121, 109, -60, 40, 18, 46, -86)
var certificate = NSData(bytes: myCertificate, length: myCertificate.count)
var buffer = [Int8](count: certificate.length, repeatedValue: 0)
certificate.getBytes(&buffer, length: certificate.length)
