STPrivilegedTask - Objective C 类

在 Mac OS X 中使用 root 权限运行 shell 命令，类似于 NSTask 的包装类 AuthorizationExecuteWithPrivileges() 在 Security API 中。

用法示例

STPrivilegedTask *privilegedTask = [[STPrivilegedTask alloc] init];

[privilegedTask setLaunchPath:@"/usr/bin/touch"];
NSArray *args = [NSArray arrayWithObject:@"/etc/my_test_file"];
[privilegedTask setArguments:args];
[privilegedTask setCurrentDirectoryPath:[[NSBundle mainBundle] resourcePath]];

//set it off
OSStatus err = [privilegedTask launch];
if (err != errAuthorizationSuccess) {
    if (err == errAuthorizationCanceled) {
        NSLog(@"User cancelled");
    } else {
        NSLog(@"Something went wrong");
    }
}

// Read output file handle for data
NSFileHandle *readHandle = [privilegedTask outputFileHandle];
NSData *outputData = [readHandle readDataToEndOfFile];
NSString *outputString = [[NSString alloc] initWithData:outputData encoding:NSUTF8StringEncoding];
