使用NSTask启动命令返回错误

问题描述

我想使用NSTask从我的应用程序启动以下命令：

I'd like to launch the following command from my application using NSTask:

这是我要做的代码：
NSPipe *管道= [NSPipe pipe];

Here is a code I do: NSPipe *pipe = [NSPipe pipe];

NSTask *task = [[NSTask alloc] init];
[task setLaunchPath: @"/bin/sh"];
[task setCurrentDirectoryPath:@"/"];
[task setStandardError:pipe];

NSArray *arguments = nil;
arguments = @[@"sudo",
              @"-u",
              @"myusername",
              @"launchctl",
              @"load",
              @"/Library/LaunchAgents/com.google.keystone.agent.plist"];

[task setArguments: arguments];

NSFileHandle * read = [pipe fileHandleForReading];

[task launch];
[task waitUntilExit];

NSData * dataRead = [read readDataToEndOfFile];
NSString * output = [[NSString alloc] initWithData:dataRead encoding:NSUTF8StringEncoding];
NSLog(@"output: %@", output);

处理后，我收到以下错误：

After processing I receive an error below:

/ bin / sh：sudo：无此类文件或目录

推荐答案

我找到了解决方法：

arguments = @[@"-c",
              @"sudo -u myusername launchctl load /Library/LaunchAgents/com.google.keystone.agent.plist"];
