推荐答案

您检查路径是否存在?在文件路径中也有一个//.尝试删除那个.

Have you checked that the path exists? also there is an // in the file path. Try to remove that one.

您还可以将您的代码发布出来，而没有我们真正不得不猜测的代码.

Could you also post you code, with out code we really have to guess.

可可错误4 表示您正在尝试移动不存在的文件，这也可能意味着目标目录不存在.

The Cocoa error 4 means that you are trying to move a file that does not exist, this could also mean that the target directory does not exists.
