You can save files to Application.persistentDataPath. Unity apps do not have write permissions to Application.dataPathon Android or iOS devices.
您可以将文件保存到Application.persistentDataPath。Unity 应用程序Application.dataPath在 Android 或 iOS 设备上没有写入权限。
Also, don't forget to join the path and the folder name with a forward slash:
另外，不要忘记用正斜杠连接路径和文件夹名称：
Application.CaptureScreenshot(Application.persistentDataPath + "/Screenshot.png");

Application.persistentDataPathof unity always points towards documents folder in IOSand to /mnt/android/data/application-bundle-identifier/for android.
And if you don't give the path for Application.CaptureScreenshotput instead give only the name for the screenshot it'll automatically get saved in the Documents folder of IOShaven't tested for android.
Application.persistentDataPathof unity 始终指向文档文件夹 inIOS和/mnt/android/data/application-bundle-identifier/for android。
如果您不提供Application.CaptureScreenshotput的路径，而只提供屏幕截图的名称，它会自动保存在IOS尚未测试的 Documents 文件夹中android。
Hope this helps.
希望这可以帮助。

static function CaptureScreen(){
var filename;
var name :String = GuiScript.stringToEdit;
var allowedScreenshots:int=1000;
for(var i = 0; i <= allowedScreenshots; i++)
{
if(Application.platform == RuntimePlatform.Android){
filename = "/mnt/sdcard/Android/data/com.xxxx.Test01/files/" + name + i + ".png";
} else {
filename = name + i + ".png";
}
if(!System.IO.File.Exists(filename))
{
Application.CaptureScreenshot(name + i + ".png" );
print("ScreenDUMP made!");
print(i);
print(name);
return;
}
else
{
print("filename already exists");
print(i);
}
}
}

There are at least 3 waysfor saving some kind of screenshot with Unity3D: Application.CaptureScreenshot, Texture2D.ReadPixelsand RenderTexture.
至少有3 种方法可以使用 Unity3D 保存某种屏幕截图：Application.CaptureScreenshot,Texture2D.ReadPixels和RenderTexture.
I only know about the first one: Application.CaptureScreenshot. It is for sure the simplest one. It doesn't take paths and it will save to Application.persistentDataPathor Application.dataPath + "/../", depending on your platform. Unfortunately there's currently no way of knowing for sure or through code only - it's just broken in that way. Also, it is slow and it may take some seconds to process. It runs as a separate process so you should have an Update or a Coroutine waiting for the file to be created before using it for anything.
我只知道第一个：Application.CaptureScreenshot。这肯定是最简单的。它不采用路径，它将保存到Application.persistentDataPath或Application.dataPath + "/../"，具体取决于您的平台。不幸的是，目前无法确定或仅通过代码知道 - 它只是以这种方式被破坏。此外，它很慢，可能需要几秒钟的时间来处理。它作为一个单独的进程运行，所以你应该有一个更新或一个协程等待文件被创建，然后再将它用于任何事情。
If you want to choose where the file will be saved with it, you need to do something like this:
如果您想选择文件的保存位置，您需要执行以下操作：
bool creatingFile = false;
string fileName = "Screenshot.png"
function Update() {
if(Input.GetMouseButtonDown(0)) {
Application.CaptureScreenshot(fileName);
creatingFile = true;
}
if (creatingFile) {
string origin = System.IO.Path.Combine(Application.persistentDataPath, fileName);
string destination = "/sdcard/ScreenCapture/" + fileName; // could be anything
if (System.IO.File.Exists(origin)) {
System.IO.File.Move(origin, destination);
creatingFile = false;
}
}
}
