        最近收入iPhone6之后将Xcode顺便升级到6.1版本，编译cocos2d-x 3.2的Helloworld项目时报错如下

         暂时的解决方法如下：
         
        打开你项目所在目录，找到里面的cocos2d-》external，在external文件夹里面搜索_arm64.a（是external里面所有的_arm64.a，不是整个计算机的！），将你搜索到的后缀为_arm64.a的文件（cocos2d-x 3.2里面是7个），之后把这些所有的文件拖到到你的Xcode项目目录里面的FrameWorks去，选择group方式，在现阶段下只能用这个方法了，大家尽情的编译吧~~~
