使用NSTask启动命令返回错误

Question

我想使用NSTask从我的应用程序启动以下命令:

sudo -u myusername launchctl load/Library/LaunchAgents/com.google.keystone.agent.plist

这是我做的代码:

[font =宋体];

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，我收到如下错误:

/bin/sh: sudo: No such file or directory

我已经找到解决办法了:

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