一个基本的IOS声音播放支持类，注释不多对付看吧

#import <Foundation/Foundation.h>#import <AudioToolbox/AudioToolbox.h>#import <AVFoundation/AVFoundation.h>@interface Sound_Base : NSObject{        float   volume;    BOOL    is_turnON;        AVAudioPlayer *mainMenuMusic_Player;        SystemSoundID btn_soundID;    SystemSoundID err_soundID;    }@property (nonatomic)               BOOL            is_turnON;@property (nonatomic)               float           volume;@property (nonatomic,retain)        AVAudioPlayer   *mainMenuMusic_player;@property (nonatomic)               SystemSoundID   btn_soundID;@property (nonatomic)               SystemSoundID   err_soundID;-(void)setSoundSwitch:(BOOL)sound_state;-(void)setUIVolume:(float)f_volume;-(void)initSound;-(void)playSysSound:(SystemSoundID)sys_sID;-(void)stopAllMusic;

#import "Sound_Base.h"@implementation Sound_Base@synthesize mainMenuMusic_player;@synthesize volume;@synthesize is_turnON;@synthesize btn_soundID;@synthesize err_soundID;-(void)dealloc{        if (self.mainMenuMusic_player.playing) {        [self.mainMenuMusic_player stop];    }    [mainMenuMusic_player   release];        if (btn_soundID) {        AudioServicesDisposeSystemSoundID(btn_soundID),btn_soundID = 0;    }        if (err_soundID) {        AudioServicesDisposeSystemSoundID(err_soundID),err_soundID = 0;    }        [super dealloc];}-(void)initSound{        NSString *mainMenuMusic_path = [ [NSBundle mainBundle] pathForResource:@"bgm_0" ofType:@"aac"];        NSURL *mainMenuMusic_url = [NSURL fileURLWithPath:mainMenuMusic_path];    self.mainMenuMusic_player = [ [AVAudioPlayer alloc] initWithContentsOfURL:mainMenuMusic_url error:nil];    self.mainMenuMusic_player.numberOfLoops = -1;    [self.mainMenuMusic_player prepareToPlay];            NSString *btnSound_path = [[NSBundle mainBundle] pathForResource:@"sys_click" ofType:@"aiff"];    AudioServicesCreateSystemSoundID( (CFURLRef)[NSURL fileURLWithPath:btnSound_path],                                     &btn_soundID);        NSString *errSound_path = [[NSBundle mainBundle] pathForResource:@"sys_error" ofType:@"aiff"];    AudioServicesCreateSystemSoundID( (CFURLRef)[NSURL fileURLWithPath:errSound_path],                                     &err_soundID);           //todo get volume  and  is silence        is_turnON = YES;        float f_volume = 1.0;        [self setUIVolume:f_volume];    }-(void)setSoundSwitch:(BOOL)sound_state{        self.is_turnON = sound_state;        if ( self.is_turnON ) {        self.mainMenuMusic_player.volume = self.volume;    } else {        self.mainMenuMusic_player.volume = 0;    }}-(void)setUIVolume:(float)f_volume{        self.volume = f_volume;        if ( self.is_turnON ) {        self.mainMenuMusic_player.volume = f_volume;    }    else{        self.mainMenuMusic_player.volume = 0;    }    }-(void)playSysSound:(SystemSoundID)sys_sID{    if ( self.is_turnON ) {        AudioServicesPlaySystemSound(sys_sID);    }    }-(void)stopAllMusic{    [self.mainMenuMusic_player stop];}@end

在应用程序初始化后创建该类对象并调用其初始化函数，声音也可继续扩展添加。需要播放时调用相应的函数即可。

部分功能还没有完成，如获取配置中的音量大小，保存音量设置，声音开关等。

另外 AudioServicesPlaySystemSound(sys_sID); 来播放是声音不知道如何控制音量～～
