在UI开发中，当我们需要为相似预制体快速复制字段绑定时，手动操作既繁琐又容易出错。本文将介绍一个高效解决这一痛点的Unity编辑器扩展工具。（适用于换皮活动）

这是一个UI环比开发的绑定复制工具，主要功能是将公共字段和[SerializeField]标记的引用字段从一个MonoBehaviour组件复制到另一个组件。它特别适用于以下场景：

1. 替换UI界面风格时复用绑定逻辑
2. 在相似组件之间快速转移引用
3. 避免重复拖拽引用字段的操作

使用方式

1. 通过 Tools > UI Binding Copier 打开窗口
2. 拖拽源组件（已配置好绑定的组件）
3. 拖拽目标组件（需要接收绑定的组件）
4. 点击 Copy Bindings 按钮完成复制

#if UNITY_EDITOR
using UnityEditor;
using UnityEngine;public class BindingCopier : EditorWindow
{private MonoBehaviour sourceComponent;private MonoBehaviour targetComponent;[MenuItem("Tools/UI Binding Copier")]public static void ShowWindow(){GetWindow<BindingCopier>("Binding Copier");}void OnGUI(){GUILayout.Label("Copy UI Bindings Between Components", EditorStyles.boldLabel);sourceComponent = (MonoBehaviour)EditorGUILayout.ObjectField("Source Component",sourceComponent,typeof(MonoBehaviour),true);targetComponent = (MonoBehaviour)EditorGUILayout.ObjectField("Target Component",targetComponent,typeof(MonoBehaviour),true);if (GUILayout.Button("Copy Bindings")){if (sourceComponent != null && targetComponent != null){CopyBindings(sourceComponent, targetComponent);EditorUtility.DisplayDialog("Success", "Bindings copied successfully!", "OK");}else{EditorUtility.DisplayDialog("Error", "Please assign both source and target components", "OK");}}EditorGUILayout.HelpBox("这个工具可以把公共字段和[SerializeField]引用从一个组件复制到另一个组件" +"当组件具有相似的字段名称和类型时，效果最佳（C#换皮用）",MessageType.Info);}public static void CopyBindings(MonoBehaviour source, MonoBehaviour target){if (source == null || target == null) return;SerializedObject sourceSerialized = new SerializedObject(source);SerializedObject targetSerialized = new SerializedObject(target);SerializedProperty iterator = sourceSerialized.GetIterator();bool enterChildren = true;while (iterator.NextVisible(enterChildren)){enterChildren = false;if (iterator.propertyType == SerializedPropertyType.ObjectReference){string propertyName = iterator.name;SerializedProperty targetProperty = targetSerialized.FindProperty(propertyName);if (targetProperty != null &&targetProperty.propertyType == SerializedPropertyType.ObjectReference &&targetProperty.objectReferenceValue == null) // Optional: only overwrite null values{targetSerialized.CopyFromSerializedProperty(iterator);}}}targetSerialized.ApplyModifiedProperties();EditorUtility.SetDirty(target);}
}
#endif

效果如下所示

只需要将预制体上的组件拖动过去 就能快速的复用绑定关系

适用场景：适用于换皮活动C#逻辑大致相似但需要单独提出逻辑
