Question

我已执行以下代码，但声音无效。在.h

 #import <AVFoundation/AVAudioPlayer.h>
 #import <AVFoundation/AVFoundation.h>

in .m

NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"sound1" ofType:@"mp3"];
NSURL *soundUrl = [NSURL fileURLWithPath:soundPath];

AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl];

[player play];

但是我听不到任何声音。实际上我想管理按钮点击声音和音量按钮，所以我使用这种方法。

Answer 1

你设定了音量吗？

[player setVolume:1.0];

播放短音的另一种方法是AudioServicesCreateSystemSoundID。

Answer 2

尝试：

 self.theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:(__bridge NSURL *)(soundUrl) error:NULL];

    self.theAudio.volume = 1.0;
    self.theAudio.delegate = self;
    [self.theAudio prepareToPlay];
    [self.theaudio play];

Answer 3

这对我来说非常适合。

将AVFoundation和AudioToolBox框架添加到项目中

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

@interface TestViewController : UIViewController
{
    SystemSoundID SoundID;
}

@implementation TestViewController
-(void) viewDidLoad {
    [super viewDidLoad];
    NSURL *url = [[NSBundle mainBundle] URLForResource:@"test" withExtension:@"caf"];
    AudioServicesCreateSystemSoundID((__bridge CFURLRef)url, &SoundID);  //When using ARC, make sure to use __bridge
 }

-(void) playSound {
     AudioServicesPlaySystemSound(SoundID);
 }

UIButton点击声音不起作用？
