if(m_bZoomViaProtocol) { ret = sendMsg(msgInfo(SID_GENERALMOVE_STOPCONTINUOUSMOVE, pPtzOperationCmd, PTZ_STOP)); } else { if (PTZ_OPT_ZOOM_WIDE != pPtzOperationCmd->cmd || PTZ_OPT_ZOOM_TELE != pPtzOperationCmd->cmd) { ret = sendMsg(msgInfo(SID_GENERALMOVE_STOPCONTINUOUSMOVE, pPtzOperationCmd, PTZ_STOP)); } }

可以通过以下两种方式来优化这段代码：

1. 减少重复代码

可以将两个分支中重复的代码提取出来，放到条件语句外面，避免重复编写代码。例如：

bool stopContinuousMove = true;
if (m_bZoomViaProtocol) {
    stopContinuousMove = true;
} else {
    if (PTZ_OPT_ZOOM_WIDE == pPtzOperationCmd->cmd || PTZ_OPT_ZOOM_TELE == pPtzOperationCmd->cmd) {
        stopContinuousMove = false;
    }
}

if (stopContinuousMove) {
    ret = sendMsg(msgInfo(SID_GENERALMOVE_STOPCONTINUOUSMOVE, pPtzOperationCmd, PTZ_STOP));
}

2. 简化条件语句

可以简化条件语句的表达式，使代码更加清晰明了。例如：

if (m_bZoomViaProtocol || (pPtzOperationCmd->cmd != PTZ_OPT_ZOOM_WIDE && pPtzOperationCmd->cmd != PTZ_OPT_ZOOM_TELE)) {
    ret = sendMsg(msgInfo(SID_GENERALMOVE_STOPCONTINUOUSMOVE, pPtzOperationCmd, PTZ_STOP));
}

这样，便可以避免代码冗余，使代码更加简洁易读。
