推荐答案

我找到了最好的办法是继承InputField。你可以看看的信号源UnityUI上到位桶。在该子类可以访问受保护的m_keyboard领域，检查是否所作所为是pressed，而不是取消，会给​​你想要的结果。使用提交的的EventSystem无法正常工作。
即使你将它集成到统一的EventSystem更好。

the best way i found is to subclass InputField. You can look into the source for the UnityUI on bitbucket. In that subclass you can access the protected m_keyboard field and check whether done was pressed AND not canceled, that will give you the desired result. Using "submit" of the EventSystem doesn't work properly. Even nicer when you integrate it into the Unity EventSystem.

事情是这样的：
SubmitInputField.cs

Something like this: SubmitInputField.cs

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using UnityEngine.Events;
using System;
using UnityEngine.EventSystems;
using UnityEngine.Serialization;

public class SubmitInputField : InputField
{
    [Serializable]
    public class KeyboardDoneEvent : UnityEvent{}

    [SerializeField]
    private KeyboardDoneEvent m_keyboardDone = new KeyboardDoneEvent ();

    public KeyboardDoneEvent onKeyboardDone {
        get { return m_keyboardDone; }
        set { m_keyboardDone = value; }
    }

    void Update ()
    {
        if (m_Keyboard != null && m_Keyboard.done && !m_Keyboard.wasCanceled) {
            m_keyboardDone.Invoke ();
        }
    }
}

编辑/ SubmitInputFieldEditor.cs

Editor/SubmitInputFieldEditor.cs

using UnityEngine;
using System.Collections;
using UnityEditor;
using UnityEngine.UI;
using UnityEditor.UI;

[CustomEditor (typeof(SubmitInputField), true)]
[CanEditMultipleObjects]
public class SubmitInputFieldEditor : InputFieldEditor
{
    SerializedProperty m_KeyboardDoneProperty;
    SerializedProperty m_TextComponent;

    protected override void OnEnable ()
    {
        base.OnEnable ();
        m_KeyboardDoneProperty = serializedObject.FindProperty ("m_keyboardDone");
        m_TextComponent = serializedObject.FindProperty ("m_TextComponent");
    }


    public override void OnInspectorGUI ()
    {
        base.OnInspectorGUI ();
        EditorGUI.BeginDisabledGroup (m_TextComponent == null || m_TextComponent.objectReferenceValue == null);

        EditorGUILayout.Space ();

        serializedObject.Update ();
        EditorGUILayout.PropertyField (m_KeyboardDoneProperty);
        serializedObject.ApplyModifiedProperties ();

        EditorGUI.EndDisabledGroup ();
        serializedObject.ApplyModifiedProperties ();
    }
}
