我想在按下按钮时发出声音。此外,还有不止一种声音。我正在使用Xcode 4.4.1和Storyboard。

在.h文件中

{
    IBOutlet UIButton *playSound;
}

我认为写这个类型的例子会很有趣,所以我写了它。它演示了按下按钮时如何播放不同的随机声音:

-(IBAction)buttonPressedWithSound:(id)sender {

    int randomSoundNumber = arc4random() % 4; //random number from 0 to 3

    NSLog(@"random sound number = %i", randomSoundNumber);

    NSString *effectTitle;

    switch (randomSoundNumber) {
        case 0:
            effectTitle = @"sound1";
            break;
        case 1:
            effectTitle = @"sound2";
            break;
        case 2:
            effectTitle = @"sound3";
            break;
        case 3:
            effectTitle = @"sound4";
            break;

        default:
            break;
    }

    SystemSoundID soundID;

    NSString *soundPath = [[NSBundle mainBundle] pathForResource:effectTitle ofType:@"caf"];
    NSURL *soundUrl = [NSURL fileURLWithPath:soundPath];

    AudioServicesCreateSystemSoundID ((CFURLRef)soundUrl, &soundID);
    AudioServicesPlaySystemSound(soundID);  
}

说明:

  • 在您的项目中添加四个声音: sound1.caf sound2.caf sound3.caf sound4的.caf

  • 将AudioToolbox框架导入您的项目。并包含在.h #import <AudioToolbox/AudioToolbox.h>

  • 不要忘记通过IBAction将您的按钮连接到 buttonPressedWithSound

我找到了这种方式,它对我有用

SystemSoundID soundID;
NSString *soundPath = [[NSBundle mainBundle] pathForResource:ClickSoundFile ofType:FileTypemp3];
NSURL *soundUrl = [NSURL fileURLWithPath:soundPath];
AudioServicesCreateSystemSoundID ((__bridge CFURLRef)soundUrl, &soundID);
AudioServicesPlaySystemSound(soundID);

*注

ClickSoundFile:声音文件名    FileTypemp3:文件类型mp3
