It wasn't removed in 3.0, it was never there. There is no way to run separate processes on the iPhone. GDAL appears to be under an MIT style license and has a library interface, so directly linking it into an iPhone app shouldn't have any legal or technical issues.
NSTask is available in ios 4, ios 3 and possibly all of them. To use NStask I had to copy the NStask header file from my mac to my project folder. Also Apple will most likely not allow an app that uses NStask in the appstore. Cydia would probably be the best place to distribute your app

它在 3.0 中没有被删除，它从来没有存在过。无法在 iPhone 上运行单独的进程。 GDAL 似乎是在 MIT 风格的许可证下并且有一个库接口，所以直接将它链接到 iPhone 应用程序应该没有任何法律或技术问题。

NSTask 可在 ios 4、ios 3 甚至所有版本中使用。要使用 NStask，我必须将 NStask 头文件从我的 mac 复制到我的项目文件夹。此外，Apple 很可能不会允许在应用商店中使用 NStask 的应用。 Cydia 可能是分发应用程序的最佳场所

只是提醒一下：
NSTask 将无法在沙箱环境下工作（您将得到“拒绝进程分叉”）。因此，将您的应用程序放入 /Applications
Just reminder:
NSTask will not work under sandbox environment (you will get "deny process-fork"). So put your application into /Applications
