Question

我在我的项目中遇到了AVAudioPlayer。情节是，在CollectionViewController＆＃34; didSelectItemAtIndexPath＆＃34;方法，我分配和初始AVAudioPlayer像贝娄，

dict=[plist objectAtIndex:indexPath.item];

    NSURL* urlPath=[NSURL new];
    urlPath=[NSURL URLWithString:[dict objectForKey:@"FilePath"]];
     NSError *error = nil;
    self.player=[[AVAudioPlayer alloc]initWithContentsOfURL:urlPath error:&error];
    NSLog(@"Error[%@]",[error localizedDescription]);
    [self.player setDelegate:self];
    [self.player prepareToPlay];

试试这个

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath  {


    NSLog(@" selected data ==%@",[yoururlarray objectAtIndex: indexPath.row]);

 urlPath=[yoururlarray objectAtIndex: indexPath.row]);

    self.player=[[AVAudioPlayer alloc]initWithContentsOfURL:urlPath error:nil];
    [self.player setDelegate:self];
    [self.player prepareToPlay];


    }

在我分配init之后，AVAudioPlayer是零
