问题描述

我正在从 cpp 移植到 Objective C.

I was porting from cpp to Objective C.

目标 C:

[pPacket SetHeaderSequenceNumber:static_cast<char>(m_transmitSequenceNumber + ASCII_ZERO)];

cpp:

pPacket->SetHeaderSequenceNumber(static_cast <char>(m_transmitSequenceNumber + ASCII_ZERO));

error:static_cast 未声明.

error:static_cast undeclared.

推荐答案

objective-c 是 c 的超集,而不是 c++,因此它不支持 static_cast.你可以只使用 c-style cast:

objective-c is a superset of c, not c++ so static_cast is not supported in it. You can just use c-style cast:

[pPacket SetHeaderSequenceNumber:(char)(m_transmitSequenceNumber + ASCII_ZERO)];
