用systemSoundID播放音效

在.h的宣告部份

#import <AudioToolbox/AudioToolbox.h> //先import AudioToolbox後才能使用這個功能

SystemSoundID magicSound; //宣告一個新的聲音叫magicSound(自已隨便取）是屬於SystemSoundID型式

-(void)playMagicSound; //宣告播放magicSound的功能

在.m的實作部份

//在init的時侯先設定magicSound要播放音效檔

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self) {

//下面紅字這一段是設定magicSound

NSURL *magicUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"magic-chime" ofType:@"wav"]];

OSStatus magicError = AudioServicesCreateSystemSoundID((__bridge CFURLRef)magicUrl, &magicSound);

if(magicError){

NSLog(@"error:%ld",magicError);

}

    }

    return self;

}

//實作playMagicSound

-(void)playMagicSound{

AudioServicesPlaySystemSound(magicSound);

}

//播放的使用方法

[self playMagicSound];
