AVAudioPlayer为零后，我的Alloc初始化

Question

我在我的project.the场景停留在AVAudioPlayer时， 在CollectionViewController的“didSelectItemAtIndexPath”的方法，我alloc和初始化AVAudioPlayer像波纹管，

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]; 

但毕竟这，它仍然nill .. 第一，我想未做的player.but没有运气财产.... 所以我尽量用this

尝试这样

-(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]; 


    }
