【iOS】Cocos2dx封裝為view方便做3D動畫效果

著作權聲明：本文為博主原創，如需轉載請註明出處。 寫在前面

本檔案只是將Cocos2dx 封裝為一個 UIView，方便直接添加使用

使用的 coco2d-x 版本為 3.13.1 添加過程

首先將 ~/cocos2d/build/cocos2d_lib.xcodeproj 添加到工程中

然後對照new出來的工程，修改配置：

然後添加兩個 Header Search Paths，同樣對照樣本工程

設定TARGETS中Header Search Paths

PROJECT中設定Header Search Paths，相對路徑

設定預先處理的宏定義，Debug和Release

修改Custom Compiler Flags

至此，不出意外編譯可以成功了。 設定view

然後在CocosViewController（我自己建立的測試介面）中設定彈出HelloWorld介面，HelloWorld介面的兩個類 AppDelegate 和 HelloWorldScene要添加到工程中。

注意這個檔案是C++混編，所以 CocosViewController.m 檔案要改尾碼為 CocosViewController.mm

此時就可以重複開啟關閉cocos動畫介面了。 釋放cocos單例 檢查單例

這裡先對所有的cocos2dx中的單例進行檢查，主要是想用Director銷毀其他的單例，經過檢查的結果也證明了王哲說的：用Director來管理項目中的單例，具體釋放在上面的 destroyCocosView 方法中。即為：

- (void)destroyCocosView{    //    cocos2d::Director::getInstance()->getTextureCache()    cocos2d::PoolManager::destroyInstance();    cocos2d::Director::getInstance()->purgeCachedData();    cocos2d::Director::getInstance()->purgeDirector();    [CCDirectorCaller destroy];}
