error:static_cast undeclared->Objective C

Objective C:

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

cpp:

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

error:static_cast undeclared.

改採用C

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)];
