void Start()
{
    EventDelegate.Add(myInput.onChange, OnInputChangeAction);
    EventDelegate.Add(myInput.onSubmit, OnSubmitAction);
    UIEventListener.Get(myInput.gameObject).onSelect = OnSelectedAction;
}

private void OnInputChangeAction()
{
    Debug.Log(myInput.value);
}

private void OnSubmitAction()
{
    Debug.Log("按下回車鍵");
}

使用全角輸入法可以實現(xiàn)段落首行縮進（windows輸入法全角/半角切換快捷鍵 shift+space）

將鼠標坐標轉(zhuǎn)到NGUI坐標

Vector3 mousePos = Input.mousePosition;     //獲取鼠標指針坐標（屏幕坐標）
Vector3 mouseWorldPos = UICamera.currentCamera.ScreenToWorldPoint(Input.mousePosition);    //當前UI相機將指針坐標轉(zhuǎn)化為世界坐標
Vector3 localPos = transform.InverseTransformPoint(mouseWorldPos);     //將指針世界坐標轉(zhuǎn)化成NGUI坐標 （transform 為父物體坐標）
