推荐答案

您正在寻找这个以获取缓存文件夹以存储临时文件文件：

You are looking for this to get tot he caches folder to store temporary files:

NSString* path = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, 
                                                      NSUserDomainMask,
                                                      YES) lastObject];

从那里你可以使用 NSFileManager 来创建并删除所需的目录。并且存储文件就像文件系统的任何其他部分一样。请注意，系统会立即清除缓存目录。

From there you can use NSFileManager to create and remove the directories you want. And store files just as to any other part of a file system. Just be aware that the system will purge the caches directory now and then.

因此，在重新启动应用之间，永远不要依赖文件剩余，也不要消失。

So never rely on file remaining, nor disappearing, between restarts of your app.
