ios - 如何在 iOS 中完成循环后停止音频

Question

   我是 iPhone 编程新手。使用下面的代码我显示带有音频的图像。我已存储在数组中的图像和音频。在 audioPlayerDidFinishPlaying 方法中完成音频后，我使用此代码显示下一个带有音频的图像。
每件事都工作得很好。但问题是，音频和图像完成后，又要从头开始。下面的代码可能存在一些问题，任何人都可以纠正它，请..

- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
  for (NSString* path in array000)
    {
        [blaukypath2 addObject:[UIImage imageWithContentsOfFile:path]];
        NSLog(@"%@",path);
    }
    currentImage++;
    NSError *error;
    if (currentImage >= blaukypath2.count) currentImage = 0;
    UIImage *blaukyyimag = [blaukypath2 objectAtIndex:currentImage];
    [img10 setImage:blaukyyimag];
    NSLog(@"%icurrentImage++ DIDF",currentImage);
    audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[audiopath2 objectAtIndex:currentImage] error:&error] ;
    audioPlayer.delegate = self;
    [audioPlayer prepareToPlay];
    [audioPlayer play];
}

Answer 1

如果您不想重复图像和音频，请删除代码中的这一行..

if (currentImage >= blaukypath2.count) currentImage = 0;

因为这一行将使你的 currentImage 为 0。因此循环将再次开始。

像这样做

- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
  for (NSString* path in array000)
    {
        [blaukypath2 addObject:[UIImage imageWithContentsOfFile:path]];
        NSLog(@"%@",path);
    }
    if (currentImage < blaukypath2.count)
    {
       currentImage++;
       NSError *error;
       UIImage *blaukyyimag = [blaukypath2 objectAtIndex:currentImage];
       [img10 setImage:blaukyyimag];
       NSLog(@"%icurrentImage++ DIDF",currentImage);
       audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[audiopath2 objectAtIndex:currentImage] error:&error] ;
       audioPlayer.delegate = self;
       [audioPlayer prepareToPlay];
       [audioPlayer play];
    }
}
