Question

我尝试将test1.csv保存到文件夹路径，Unity说拒绝访问：

如何在Mac OS Sierra上授予权限？我已经做过CMD + I并给了“大家”读取+写入文件和文件夹，但它没有帮助..谷歌也没有帮助我。

如何允许权限？提前谢谢！

TextWriter tw1 = new StreamWriter ("/Users/X/testunity/test1.csv, true);
tw1.WriteLine ("testfile");
tw1.Close ();

始终写入Unity中的Application.persistentDataPath+folder路径。这将保证代码与Unity支持的大多数平台兼容。

string path = Path.Combine(Application.persistentDataPath, "data");
path = Path.Combine(path, "test1.csv");

//Create Directory if it does not exist
if (!Directory.Exists(Path.GetDirectoryName(path)))
{
    Directory.CreateDirectory(Path.GetDirectoryName(path));
}

using (StreamWriter writer = new StreamWriter(path))
{
    writer.WriteLine("testfile");
}

就个人而言，File.WriteAllBytes要写入文件，所以我建议除非你想逐行写入文件。

string path = Path.Combine(Application.persistentDataPath, "data");
path = Path.Combine(path, "test1.csv");

//Create Directory if it does not exist
if (!Directory.Exists(Path.GetDirectoryName(path)))
{
    Directory.CreateDirectory(Path.GetDirectoryName(path));
}

byte[] data = Encoding.ASCII.GetBytes("testfile");
File.WriteAllBytes(path, data);

Unity3d写入拒绝mac访问的文件路径
