播放声音效果Xcode 5

Question

我想这样做，每次我点击图片，它会发出声音。在“链接框架和库”AudioToolbox和GameViewController.h添加：

#import <AudioToolbox/AudioToolbox.h>
@interface GameViewController : UIViewController
{
SystemSoundID PlaySoundID;
}
- (IBAction)PlayAudioButton:(id)sender;

(用按钮连接)。

在GameViewController.m中添加以下内容：

- (void)viewDidLoad
{

NSURL *SoundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"Sound"    ofType:@"wav"]];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)SoundURL, &PlaySoundID);
}

- (IBAction)PlayAudioButton:(id)sender {

AudioServicesPlaySystemSound(PlaySoundID);

}

毕竟没有错误但听起来不管用.出什么问题了？

谢谢。

Answer 1

用这个代替：

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
                                          pathForResource:@"yourSound"
                                          ofType:@"mp3"]];

AVAudioPlayer sound = [[AVAudioPlayer alloc]
                    initWithContentsOfURL:url
                    error:nil];

[sound play];

不确定我是否正确地理解了你的问题，但当你按下按钮时，我就会听到定制的声音。

一定要

#import <AVFoundation/AVFoundation.h>

在.h或.m文件中

为类创建一个AVAudioPlayer *audioPlayer属性(在.h或.m中)，然后执行以下操作：

-(void)viewDidLoad{
    [super viewDidLoad]
    NSError *error;
    NSString *soundPath =[[NSBundle mainBundle] pathForResource:@"Sound" ofType:@"wav"];
    NSURL *soundURL = [NSURL fileURLWithPath:soundPath];
    AVAudioPlayer *theAudioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:&error];
    [theAudioPlayer prepareToPlay];
    self.audioPlayer = theAudioPlayer;
}

- (IBAction)PlayAudioButton:(id)sender{
    [self.audioPlayer play];
}
