From U3D to iOS
實(shí)現(xiàn)原理
1.unity工程目錄創(chuàng)建2個(gè)文件?NativeCallProxy.m、NativeCallProxy.h?并且放到Unity工程目錄Plugins/iOS/unity_ios_plus目錄下
2.創(chuàng)建C#調(diào)用腳本?定義對(duì)應(yīng).mm腳本的 調(diào)用接口，調(diào)用也如下
From U3D to iOS
實(shí)現(xiàn)原理
由于U3D無法直接調(diào)用Objc或者Swift語言聲明的接口，幸好U3D的主要語言是C#，因此可以利用C#的特性來訪問C語言所定義的接口，然后再通過C接口再調(diào)用ObjC的代碼（對(duì)于Swift代碼則還需要使用OC橋接）。
下面演示：利用C#的特性來訪問C語言所定義的接口，然后再通過C接口再調(diào)用ObjC的代碼
1.unity工程目錄創(chuàng)建2個(gè)文件?NativeCallProxy.m、NativeCallProxy.h?并且放到Unity工程目錄Plugins/iOS/unity_ios_plus目錄下
