Question

我将文件保存在iPhone模拟器的可写目录中。可以在运行时动态删除和创建文件。我想使用目录路径而不是文件名列出特定目录中的这些文件。

示例：

/Users/mine/Library/Application Support/iPhone Simulator/7.1/Applications/022F7891-1983-4791-AB59-451B2EAF4FB8/Documents/stage/stage_1.json
/Users/mine/Library/Application Support/iPhone Simulator/7.1/Applications/022F7891-1983-4791-AB59-451B2EAF4FB8/Documents/stage/stage_2.json
/Users/mine/Library/Application Support/iPhone Simulator/7.1/Applications/022F7891-1983-4791-AB59-451B2EAF4FB8/Documents/stage/stage_24.json
/Users/mine/Library/Application Support/iPhone Simulator/7.1/Applications/022F7891-1983-4791-AB59-451B2EAF4FB8/Documents/stage/stage_3.json
/Users/mine/Library/Application Support/iPhone Simulator/7.1/Applications/022F7891-1983-4791-AB59-451B2EAF4FB8/Documents/stage/stage_4.bmp

vector = getFilesInDir（FileUtils :: getInstance（） - ＆gt; getWritablePath（）+ string（＆＃34; Documents / stage＆＃34;），＆＃34; json＆＃34;）;

vector =＆gt; （＆＃34; stage_1.json＆＃34;，＆＃34; stage_1.json＆＃34;，＆＃34; stage_1.json＆＃34;，＆＃34; stage_1.json＆＃34;）

cocos2dx中没有用于列出目录内容的跨平台API。您可以在创建文件名时将其存储在数组中。

如果您只想按名称阅读文件，则需要在CCFileUtils

中插入搜索路径的文件夹路径以搜索路径

FileUtils *fileUtils = FileUtils::getInstance();
vector<string> searchPaths = fileUtils->getSearchPaths();
string path = fileUtils->getWritablePath() + "stage";
searchPaths.insert(searchPaths.begin(), path);
fileUtils->setSearchPaths(searchPaths);

如何在cocos2d-x上的目录中列出文件？
