NSTask and NSPipe example to comunicate with the command line objective-c
提问by objectiveccoder001
Can someone show a quick example on how to use NSTask and NSPipe in conjunction to do this:
有人可以展示一个关于如何结合使用 NSTask 和 NSPipe 来执行此操作的快速示例：
Charlie AI - run through terminal to comunicate with the AI
Charlie AI - 通过终端运行与 AI 通信
I want to create a nice GUI for it using xcode and objective c. I want to have 2 NSTextFields for the charlie's response and user input. Then have a send button to send the user input to the command line, then get the charlie's response and post it in the NSTextField.
我想使用 xcode 和目标 c 为它创建一个很好的 GUI。我想有 2 个 NSTextFields 用于 charlie 的响应和用户输入。然后有一个发送按钮将用户输入发送到命令行，然后获取查理的响应并将其发布到 NSTextField 中。
I can handle the GUI stuff (NSTextField, ect.) But I need help with the objective-c coding part.
我可以处理 GUI 的东西（NSTextField 等），但我需要 Objective-c 编码部分的帮助。
Thanks!

Apple have some nice sample code that shows how to do most of that... http://developer.apple.com/mac/library/samplecode/Moriarity/
Apple 有一些不错的示例代码，展示了如何完成大部分工作...... http://developer.apple.com/mac/library/samplecode/Moriarity/
TaskWrapper.mcontains all the clever stuff, but since you want to be able to send data to the task, you'll need to extend it a little, like so:
TaskWrapper.m包含所有聪明的东西，但是由于您希望能够将数据发送到任务，您需要对其进行一些扩展，如下所示：
[task setStandardInput: [NSPipe pipe]];
[task setStandardInput: [NSPipe pipe]];
To send input to the task, you can then do:
要将输入发送到任务，您可以执行以下操作：
[[[task standardInput] fileHandleForWriting] writeData: ...];
[[[task standardInput] fileHandleForWriting] writeData: ...];
To turn the NSTextField's value into data, you can do something like this:
要将 NSTextField 的值转换为数据，您可以执行以下操作：
NSData *data = [[inputTextField stringValue] dataUsingEncoding:NSUTF8StringEncoding];
NSData *data = [[inputTextField stringValue] dataUsingEncoding:NSUTF8StringEncoding];
...and to set the current working directory for your sub-task, use [NSTask setCurrentDirectoryPath:]
...并为您的子任务设置当前工作目录，请使用[NSTask setCurrentDirectoryPath:]
e.g.
例如
[task setCurrentDirectoryPath:@"/blah/blah"];
[task setLaunchPath:@"/blah/blah/server.sh"];
.... (other setup code)
[task launch];

There's also AMShellWrapper sample code which improves on moriarity.
还有 AMShellWrapper 示例代码，它改进了moriarity。
