    1.控制器代码

    #import "ViewController.h"

    #import <AVFoundation/AVFoundation.h>

    #import "RYAVTool.h"

     

    @interface ViewController ()

     

    @property(nonatomic,strong)NSMutableDictionary*allAvID;

     

    @end

     

    @implementation ViewController

     

    - (void)viewDidLoad {

        [super viewDidLoad];

        

    }

     

     

    -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

    {

       self.allAvID= [RYAVTool playAVWithName:@"m_06.wav"];

    }

    //内存警告时清理缓存

    - (void)didReceiveMemoryWarning {

        [super didReceiveMemoryWarning];

        [self.allAvID enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {

            AudioServicesDisposeSystemSoundID([obj unsignedIntValue]);

        }];

        

        

    }

    @end

     

    2.辅助工具类代码

    #import <Foundation/Foundation.h>

     

    @interface RYAVTool : NSObject

     

    +(NSMutableDictionary*)playAVWithName:(NSString*)name;

     

    @end

     

    #import "RYAVTool.h"

    #import <AVFoundation/AVFoundation.h>

     

     

    static NSMutableDictionary *_allID;

    static SystemSoundID _currentData;

     

    @implementation RYAVTool

     

    +(void)load

    {

        if (_allID==nil) {

            _allID =[[NSMutableDictionary alloc]init];

        }

    }

     

    +(NSMutableDictionary*)playAVWithName:(NSString*)name

    {

        if (!name) {

            return _allID;

        }

        

        NSString*path=[[NSBundle mainBundle]pathForResource:name ofType:nil];

        if (!path) {

            return _allID;

        }

        NSURL *url=[NSURL fileURLWithPath:path];

        _currentData=[_allID[name] unsignedIntValue];

        if (!_currentData) {

            //创建音频播放文件

            AudioServicesCreateSystemSoundID((__bridge CFURLRef)(url), &_currentData);

            //保存

            _allID[name]=@(_currentData);

        }

        //播放

        AudioServicesPlayAlertSound(_currentData);

        

        return _allID;

    }

    @end
