原来代码
bool SkeletonRenderer::setAttachment (const std::string& slotName, const std::string& attachmentName) {
return spSkeleton_setAttachment(_skeleton, slotName.c_str(), attachmentName.c_str()) ? true : false;
}

改为

bool SkeletonRenderer::setAttachment (const std::string& slotName, const std::string& attachmentName) {
return spSkeleton_setAttachment(_skeleton, slotName.c_str(), attachmentName.empty() ? nullptr : attachmentName.c_str()) ? true : false;
}

原因attachment May be 0 to clear the attachment for the slot
设置slot后就不能设置隐藏
