iOS简单的音效播放单例 （您可照搬代码）

.h

#import <Foundation/Foundation.h>

@interface MusicPlayManager : NSObject

+ (BOOL)playMusic:(NSString *)filename;//播放音乐

+ (void)pauseMusic:(NSString *)filename;//暂停播放

+ (void)stopMusic:(NSString *)filename;//停止音乐

@end

.m

#import "MusicPlayManager.h"

#import <AVFoundation/AVFoundation.h>

@interface MusicPlayManager()

@end

@implementation MusicPlayManager

*存放所有的音乐播放器

*/

//缓冲

//存入字典
