IOS基本聲音播放類

一個基本的IOS聲音播放支援類，注釋不多對付看吧

#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;

在應用程式初始化後建立該類對象並調用其初始化函數，聲音也可繼續擴充添加。需要播放時調用相應的函數即可。

部分功能還沒有完成，如擷取配置中的音量大小，儲存音量設定，聲音開關等。

另外  AudioServicesPlaySystemSound(sys_sID); 來播放是聲音不知道如何控制音量～～
