1、以一个点击按钮播放音效为例

• 引入音频管理文件

#import 
    

2、创建枚举值

typedef NS_ENUM(NSInteger, VoiceType) {        VoiceTypeIsWav = 0, // wav        VoiceTypeIsMp3 = 1, // mp3        VoiceTypeIsAPE = 2, // ape        VoiceTypeIsOther = 3 // 其他    };    NSString *const VoiceTypeStringMap[] = {        [VoiceTypeIsWav] = @"wav",        [VoiceTypeIsMp3] = @"mp3",        [VoiceTypeIsAPE] = @"ape",        [VoiceTypeIsOther] = @"Other"    };

3、播放音频文件方法抽取

/************ 播放音效 *****************************/    - (void)playSoundEffect:(NSString *)name withType:(VoiceType)type {        // 播放扫描二维码的声音        SystemSoundID soundID;        NSString *strSoundFile = [[NSBundle mainBundle] pathForResource:name ofType:VoiceTypeStringMap[type]];        AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:strSoundFile],&soundID);        AudioServicesPlaySystemSound(soundID);    }

4、按钮点击播放音效

/************ 点击开关灯按钮就会调用 *****************************/    - (void)OpenOrClosedLamp:(UIButton *)button {        // 播放音效        [self playSoundEffect:@"btn_press_voice_2" withType:VoiceTypeIsWav];    }
