匯入框架：

程式碼：

#import <UIKit/UIKit.h>
#import <AudioToolbox/AudioToolbox.h>

@interface MsgPlaySound : NSObject
{
    SystemSoundID sound;//系統聲音的id 取值範圍為：1000-2000
}
- (id)initSystemShake;//系統 震動
- (id)initSystemSoundWithName:(NSString *)soundName SoundType:(NSString *)soundType;//初始化系統聲音
- (void)play;//播放
@end
 

#import "MsgPlaySound.h"

@implementation MsgPlaySound

- (id)initSystemShake
{
    self = [super init];
    if (self) {
        sound = kSystemSoundID_Vibrate;//震動
    }
    return self;
}

- (id)initSystemSoundWithName:(NSString *)soundName SoundType:(NSString *)soundType
{
    self = [super init];
    if (self) {
        NSString *path = [NSString stringWithFormat:@"/System/Library/Audio/UISounds/%@.%@",soundName,soundType];
        //[[NSBundle bundleWithIdentifier:@"com.apple.UIKit" ]pathForResource:soundName ofType:soundType];//得到蘋果框架資源UIKit.framework ，從中取出所要播放的系統聲音的路徑
        //[[NSBundle mainBundle] URLForResource: @"tap" withExtension: @"aif"];  獲取自定義的聲音
        if (path) {
            OSStatus error = AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:path],&sound);
            
            if (error != kAudioServicesNoError) {//獲取的聲音的時候，出現錯誤
                sound = nil;
            }
        }
    }
    return self;
}

- (void)play
{
    AudioServicesPlaySystemSound(sound);
}
 

1.聲音格式是MP3或m4r的需要轉成caf格式（可先轉成aif , aiff，然後修改後綴）
2.路徑在/System/Library/Audio/UISounds 裡，需要更改的可以根據以下列表進行替換
