接上一節(jié)： iOS與unity交互混編, 閉包方式實(shí)現(xiàn)互相調(diào)用

插件添加到工程

如果插件只包含 .h/.m/.mm/.c/.cpp/.a 文件，直接放入 Unity Assets/Plugins/iOS 目錄即可维苔。在 Unity 導(dǎo)出 Xcode 工程時(shí)徘意，這些文件會(huì)放置在Unity-iPhone/Libraries/Plugins/iOS目錄。

如果插件包含 .framework/.bundle 文件净嘀，需要在 Unity 導(dǎo)出 XCode 工程之后报咳，手動(dòng)或利用unity的腳本功能，加入 Xcode 工程中挖藏。勾選Copy items if needed暑刃，選擇Create groups，勾選Add to targets: Unity-iPhone膜眠。

導(dǎo)出iOS工程之后的設(shè)置

如果每次導(dǎo)出 Xcode 之后手動(dòng)修改 PBXProject 和 Plist稍走，將會(huì)非常麻煩。UnityEditor 提供一個(gè)[PostProcessBuild]標(biāo)簽柴底，可以幫助我們在導(dǎo)出 Xcode 之后執(zhí)行一些自動(dòng)化操作婿脸。

標(biāo)記 PostProcessBuild 方法
