1.PC平台下

//Window剪切板处理

GUIUtility.systemCopyBuffer = copyText;

2.Android平台下

先添加jar包，放置在Plugins->Android->bin目录下

jar包中代码（反编译出来的）:

package com.apowo.clipboard;
 
import android.content.ClipData;
import android.content.ClipboardManager;
import android.content.Context;
import android.os.Looper;
 
public class ClipboardTools
{
  public static ClipboardManager clipboard = null;
 
  public static void copyTextToClipboard(Context activity, String str) throws Exception
  {
    if (Looper.myLooper() == null) {
      Looper.prepare();
    }
    clipboard = (ClipboardManager)activity.getSystemService("clipboard");
 
    ClipData textCd = ClipData.newPlainText("data", str);
    clipboard.setPrimaryClip(textCd);
  }
}

引入jar包中的内容：

//Android剪切板处理
AndroidJavaObject androidObject = new AndroidJavaObject("com.apowo.clipboard.ClipboardTools");
AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity");
// 复制到剪贴板
androidObject.CallStatic("copyTextToClipboard", activity, copyText);

3.IOS平台下

先添加.h和.mm文件，.mm文件是对.h文件中定义方法的具体实现

.h文件：

@ interface Clipboard : NSObject
 
extern "C"
{
                 /*  compare the namelist with system processes  */
                 void _copyTextToClipboard(const char *textList);
}
 
@end

.mm文件:

#import "Clipboard.h"
@implementation Clipboard
//将文本复制到IOS剪贴板
- (void)objc_copyTextToClipboard : (NSString*)text
{
     UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
     pasteboard.string = text;
}
@end
 
extern "C" {
     static Clipboard *iosClipboard;
 
     void _copyTextToClipboard(const char *textList)
    {  
        NSString *text = [NSString stringWithUTF8String: textList] ;
 
        if(iosClipboard == NULL)
        {
            iosClipboard = [[Clipboard alloc] init];
        }
 
        [iosClipboard objc_copyTextToClipboard: text];
    }
 
}

然后，在代码里引用：

引入头DllImport：

1

using System.Runtime.InteropServices;

引入方法：

#if UNITY_IPHONE
            /* Interface to native implementation */
            [DllImport ("__Internal")]
            private static extern void _copyTextToClipboard(string text);
#endif

调用方法：

1

_copyTextToClipboard(copyText);

完整代码：

    public void OnButtonClick() {
        string copyText = input.text.ToString();
 
#if UNITY_IPHONE
            /* Interface to native implementation */
            [DllImport ("__Internal")]
            private static extern void _copyTextToClipboard(string text);
#endif
 
#if UNITY_STANDALONE_WIN
        //Window剪切板处理
        GUIUtility.systemCopyBuffer = copyText;
#elif UNITY_ANDROID
        //Android剪切板处理
        AndroidJavaObject androidObject = new AndroidJavaObject("com.apowo.clipboard.ClipboardTools");
        AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity");
        // 复制到剪贴板
        androidObject.CallStatic("copyTextToClipboard", activity, copyText);
 
#elif UNITY_IPHONE
         _copyTextToClipboard(copyText);
 
#endif
    }
