Expected function body after function declarator
提问by Zophiel
Trying to compile a unity3d project in xcode but i'm getting the following compile errors on the function below. Anybody know what the cause is?
试图在 xcode 中编译一个 unity3d 项目，但我在下面的函数中遇到以下编译错误。有谁知道是什么原因？

Oke turns out the problem lies inherently within Unity 3.3. How ever, this is easilly fixed by going into the player settings for iOS and readjusting the value for the tagrt SDK from "4.2" to "latest since 4.2"
好吧，原来问题出在 Unity 3.3 中。但是，通过进入 iOS 的播放器设置并将 tagrt SDK 的值从“4.2”重新调整为“自 4.2 以来的最新版本”，可以轻松解决此问题
