Hello, I am trying to predefined list of avtars for my game by using below Snippet.

public void createAvtarList(){
    for(int i=1; i<9;i++){     filePath = Application.dataPath + "/Marine/Resources/MainMenu/btnAvtar" + i + ".png";
   Debug.Log(filePath);
   filePath = filePath.Replace("/Data/","/");
   Debug.Log("New File Path  " + filePath);
   if(FB.IsLoggedIn)               avatarService.CreateAvatar(("btnAvtar" + i),Login.fbUserName,filePath,avatarName,null);
            
    }
}

and I am getting below error whenever i call the createAvtarList(), from the Xcode Debugger

Hi marine,

This error occurred when your file does not exist or given directory does not exist.

To check your file exists through code, you can do something like this

string root = Application.dataPath.Substring(0, Application.dataPath.Length - 4) + "Documents";

 

            if (System.IO.Directory.Exists(root))

 

            {

 

                return root; // for phone

 

            }

 

            else

 

            {

 

                return ""; // for development on PC (not phone)

 

            }

@sshukla Thank you. can you give me a simple static path to work for iOS or mobile device please. I am studying the tutorial but I am unable to give the exact path for the image file needed to pass as a signature.

---

use Application.persistentDataPath.
string path = "file://" + System.IO.Path.Combine(Application.persistentDataPath, "Images/image.png");

You can also see the related thread on unity forum.. How to get file path on ios using Unity3d

@sshukla I tried to use the above code and I am getting the error As :
DirectoryNotFoundException: Could not find a part of the path "/file:/Marine/Resources/MainMenu/btnAvtar1.png".
  at System.IO.FileStream..ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean anonymous, FileOptions options) [0x00000] in <filename unknown>:0

So, when i read about unity3d ios file access, the correct path is something like this.
"<path to player app bundle> / <AppName.app> / Documents"

---

your file path might be like this.
/var/mobile/Applications/70BC50EA-9A96-4ABE-96A8-6F309356C8E1/My.app/Documents/btnAvtar1.png

And make sure your file exists.
Go into Xcode's organizer, download your app's data directory and you can confirm if what you think should be there really is.
