将IOS本机对象传递回unity3d [英] Passing IOS native objects back to unity3d

问题描述

我用几种简单的方法实现了IOS插件，以使我的统一应用程序与本地静态库相互干扰.

I implemented IOS plugin with couple of simple methods to interract my unity application with native static library.

我面临的问题是将本机UI元素(对象)传回统一.

The problem, I faced, is passing back native UI elements(objects) to unity.

F.e本机SDK具有创建徽章(UIView)的方法，另一方面，我具有统一的按钮(可以是GUI元素或某些3d对象，无论如何)

F.e native SDK has method that creates badge (UIView), on the other hand I have button in unity (it could be GUI element or some 3d object, whatever)

我可以通过插件通过统一方式访问此方法，例如:

I access this method from unity through my plugin, smth like:

[DllImport("__Internal")]    
private static extern void XcodePlugin_GetBadgeView();    

及以下:

void XcodePlugin_GetBadgeView()
{
    // Generate native UIView 
    UIView *badge = [Badge badge];

    ???? Return UIView badge instance to unity (hm)?!
}

所以我需要类似的东西:

So I need something like:

[someViewOrObject addSubView:badge];

但内在统一.

我知道有能力将信息发送回团结:

I know there is ability to send message back to unity:

UnitySendMessage( "UnityCSharpClassName" , "UnityMethod", "WhateverValueToSendToUnity");

但是WhateverValueToSendToUnity应该是UTF8字符串.

but WhateverValueToSendToUnity should be UTF8 string.

结论:

只有一个主意，我必须将坐标从unity传递到本机插件，然后将徽章添加到这些坐标(不确定这是最好的解决方案):

Only one idea I have to pass coordinates from unity to native plugin, and then add badge to these coordinates(not sure this is best solution):

[DllImport("__Internal")]    
private static extern void XcodePlugin_AddBadgeViewToCoordinates(x,y);

推荐答案

如果仅用于徽章坐标，则您的想法似乎很好.

If it's just for the badge coordinates, your idea seems fine.

如果您想将其他东西从iOS移植到Unity中，我认为没有其他选择.我唯一想到的另一种方法是将数据保存在文件中(例如，在NSTemporaryDirectory中)，然后使用UnitySendMessage将文件名作为UTF8String传递回去.我之前曾使用过这种技术(将图像和JSON文件传递给Unity). iOS中会自动清理该目录中的文件.

If there are other things you'd like to get from iOS into Unity, I don't think there are many other options. The only other way that I can think of is to save the data in a file (eg, in NSTemporaryDirectory) and then pass the filename back as a UTF8String using UnitySendMessage. I've used this technique before (to pass images and JSON files) to Unity. Files in that directory get cleaned up automatically by iOS.
