coco2dx 线程池AsyncTaskPool的使用方法

AsyncTask是什么呢？它是对线程池和Handler的封装；用线程池来挺处理后台任务，用Handler来处理与UI的交互。

struct AsyncData{std::string zipFile;//zip包bool succeed;};AsyncData* asyncData = new AsyncData;asyncData->zipFile = zip;asyncData->succeed = false;//解压成功后调用此回调方法std::function<void(void*)> decompressFinished = [this](void* param) {auto dataInner = reinterpret_cast<AsyncData*>(param);delete dataInner;};AsyncTaskPool::getInstance()->enqueue(AsyncTaskPool::TaskType::TASK_OTHER, decompressFinished, (void*)asyncData, [this, asyncData]() {// Decompress all compressed filesif (decompress(asyncData->zipFile))//解压中......解压完成后会调用decompressFinished回调方法{asyncData->succeed = true;}_fileUtils->removeFile(asyncData->zipFile);});
