Met error: ArgumentNullException: Value cannot be null.
I have a code: public IEnumerator Download(ResourceModel model,List urls) {
for(int i=0; i< urls.Count; i++)
{
Debug.Log(urls[i]);
using (UnityWebRequest www = UnityWebRequest.Get(urls[i]))
{
StartCoroutine(ShowProgress(www, model.data[i].dataName));
yield return www.SendWebRequest();
string path = Path.Combine(Application.persistentDataPath, model.data[i].dataName);
Debug.Log(path);
File.WriteAllBytes(path, www.downloadHandler.data);
}
}
}
IEnumerator ShowProgress(UnityWebRequest www, string fileName)
{
_downloadInfoTxt.text = "downloading " + fileName + " file ...";
while (!www.isDone)
{
_loadingBar.fillAmount = www.downloadProgress;
_percenTxt.text = Mathf.RoundToInt(www.downloadProgress * 100) + "%";
Debug.Log("Downloaded: " + www.downloadProgress * 100);
Debug.Log("is Done: " + www.isDone);
yield return new WaitForEndOfFrame();
}
Debug.Log("=====>> da ra ngoai roi");
_loadingBar.fillAmount = 1;
_percenTxt.text = "100%";
_downloadInfoTxt.text = "The " + fileName + " file dowload is completed.";
}
When i call download IENumrator it work in Unity Editor, but i met the error when run on iOS.
