震动和声音的实现是调用系统AudioServicesPlaySystemSound()函数实现的, 代码如下:

////  ViewController.m//  摇一摇////  Created by Wangjunling on 16/4/6.//  Copyright © 2016年 Wangjunling. All rights reserved.//#import "ViewController.h"//需要导入AVFoundation#import <AVFoundation/AVFoundation.h>@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad {    [super viewDidLoad];  }/** 摇晃开始 */- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {    NSLog(@"yaohuang");    //设置震动    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);        //设置声音    SystemSoundID soundID;    NSString *path = [[NSBundle mainBundle] pathForResource:@"song"ofType:@"aac"];        AudioServicesCreateSystemSoundID((__bridge CFURLRef _Nonnull)([NSURL fileURLWithPath:path]), &soundID);        //播放声音        AudioServicesPlaySystemSound (soundID); }/** 摇晃结束 */- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {    NSLog(@"endshake");}- (void)didReceiveMemoryWarning {    [super didReceiveMemoryWarning];    // Dispose of any resources that can be recreated.}@end

注意: 更正一下错误, 代码中使用的音效格式为aac, 最近刚发现aac格式的系统并不支持, 系统可以支持的格式一共有三种: caf, aif, wav, 所以码友们, 在练习demo是注意下喽
