Working with screenshots in iOS.

Questions & Answers
1

I have a challenge that I’m pretty stuck with, and would appreciate some assistance.

I need an app to take a screenshot, and shortly after, show that screenshot to the user.

I made this work in a OS X project, where I simply dumped the screenshot in the hd root, and then loaded it with www (file://screenshot.png)

This worked quite well.

But I need it to work for iOS and android, and here it becomes tricky.

My current code looks like so :

			Application.CaptureScreenshot("Screenshot.png");
			StartCoroutine("GetScreenshot");

IEnumerator GetScreenshot () {
		string path = Application.dataPath.Substring (0, Application.dataPath.Length - 5); 
        // Strip application name 
        path = path.Substring(0, path.LastIndexOf('/'));  
        path = "file://" + path + "/Documents/Screenshot.png"; 
		WWW www = new WWW(path);// previously "file://Screenshot.png"
		print(path);
		yield return www;
		recentScreenshot = new Texture2D(1, 1);
		www.LoadImageIntoTexture(recentScreenshot);
        mLobbyDisplay = true;
		screen = "picture";
	}

I found in iOS that I had to use Application.persistentDataPath for saving files.
