如何使用NSTask授予权限 - objective-c

#import <Foundation/NSTask.h>

NSTask *task = [[NSTask alloc] init];

[task setLaunchPath:@"/usr/bin/sudo"];
[task setArguments:@[@"command", @"parameter"]];

AuthorizationRef authorizationRef;
OSStatus status = AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults, &authorizationRef);
if (status == errAuthorizationSuccess) {
    AuthorizationItem authItem = {kAuthorizationRightExecute, 0, NULL, 0};
    AuthorizationRights authRights = {1, &authItem};
    AuthorizationFlags flags = kAuthorizationFlagDefaults | kAuthorizationFlagInteractionAllowed | kAuthorizationFlagPreAuthorize | kAuthorizationFlagExtendRights;
    status = AuthorizationCopyRights(authorizationRef, &authRights, kAuthorizationEmptyEnvironment, flags, NULL);
    if (status == errAuthorizationSuccess) {
        [task setAuthorizationRef:authorizationRef];
    }
}

[task launch];

[task waitUntilExit];

NSPipe *pipe = [NSPipe pipe];
[task setStandardOutput:pipe];
[task setStandardError:pipe];
NSFileHandle *file = [pipe fileHandleForReading];
NSData *data = [file readDataToEndOfFile];
NSString *output = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
