在 cocos2d-x 2.x 中的 AssetsManager 包中提供了一個 CreateDirectory 方法。這個方法可以跨平臺支持創(chuàng)建文件夾。在實際項目中運(yùn)行沒有問題。
bool AssetsManager::createDirectory(const char *path)
{
#if (CC_TARGET_PLATFORM != CC_PLATFORM_WIN32)
mode_t processMask = umask(0);
int ret = mkdir(path, S_IRWXU | S_IRWXG | S_IRWXO);
umask(processMask);
if (ret != 0 (errno != EEXIST))
{
return false;
}
return true;
#else
BOOL ret = CreateDirectoryA(path, NULL);
if (!ret ERROR_ALREADY_EXISTS != GetLastError())
{
return false;
}
return true;
#endif
}
void UpdateLayer::reset(cocos2d::CCObject *pSender)
{
pProgressLabel->setString(" ");
// Remove downloaded files
#if (CC_TARGET_PLATFORM != CC_PLATFORM_WIN32)
string command = "rm -r ";
// Path may include space.
command += "\"" + pathToSave + "\"";
system(command.c_str());
#else
string command = "rd /s /q ";
// Path may include space.
command += "\"" + pathToSave + "\"";
system(command.c_str());
#endif
// Delete recorded version codes.
getAssetsManager()->deleteVersion();
createDownloadedDir();
}
The iOS Simulator libSystem was initialized out of order. This is most often caused by running host executables or inserting host dylibs. In the future, this will cause an abort.
lfs.rmdir 命令 和 os.remove 命令一樣，只能刪除空文件夾。因此實現(xiàn)類似 rm -rf 的功能， 必須要遞歸刪除文件夾中所有的文件和子文件夾。
require("lfs")
function os.exists(path)
return CCFileUtils:sharedFileUtils():isFileExist(path)
end
function os.mkdir(path)
if not os.exists(path) then
return lfs.mkdir(path)
end
return true
end
function os.rmdir(path)
print("os.rmdir:", path)
if os.exists(path) then
local function _rmdir(path)
local iter, dir_obj = lfs.dir(path)
while true do
local dir = iter(dir_obj)
if dir == nil then break end
if dir ~= "." and dir ~= ".." then
local curDir = path..dir
local mode = lfs.attributes(curDir, "mode")
if mode == "directory" then
_rmdir(curDir.."/")
elseif mode == "file" then
os.remove(curDir)
end
end
end
local succ, des = os.remove(path)
if des then print(des) end
return succ
end
_rmdir(path)
end
return true
end
