在iOS5中播放wav文件

Question

我一直有一些关于wav文件最近没玩的问题，我使用的是我两年前编写的代码（为ARC调整过），我很好奇，如果我这样做是最好的方式，因为iOS已经改变了从那以后呢？

@interface ViewController ()
@property (nonatomic, strong) AVAudioPlayer *buttonAudioPlayer;
@end

@implementation ViewController
@synthesize buttonAudioPlayer;

- (void)viewDidLoad {
    [super viewDidLoad];

    NSBundle *bundle = [NSBundle mainBundle];
    NSError *error = nil;

    NSURL *soundURL = [NSURL fileURLWithPath:[bundle pathForResource:@"buttonClick_002" ofType:@"wav"]];
    [self setButtonAudioPlayer:[[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:&error]];
    [buttonAudioPlayer prepareToPlay];
}

- (IBAction)buttonPressed {
    NSLog(@"Button Pressed ...");
    [[self buttonAudioPlayer] play];
}
