ios - iOS上相同声音的多个实例

Question

我在做一个泡泡游戏，碰到一点障碍:/
我有声音(pop.mp3)，每次听到气泡之一时，都需要播放此声音
所有气泡都是调用相同方法的按钮(-(IBACTION)bubblePop)
我在Viewdidload方法中初始化了AVAudioPlayer
并在bubblePop方法中调用它的播放功能
这显然是行不通的，但是因为气泡的流行声音一次只能播放一次，所以它不会像我期望的那样重叠
有谁知道我该如何解决？
额外信息
如果我在bubblePop中初始化音频播放器，我什么都听不到

Answer 1

您应该在bubblePop中初始化AVPlayer并对其保持强烈引用。
试试这个:

@interface ViewController()
@property (strong, nonatomic) NSMutableDictionary *players;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.players = [[NSMutableDictionary alloc] init];
}

- (void)bubblePop {
    NSURL *URL = your sound URL;

    AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:URL];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(itemDidFinishPlaying:) name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem];

    AVPlayer *player = [[AVPlayer alloc] initWithPlayerItem:playerItem];
    self.players[playerItem] = player;

    [player play];
}


-(void)itemDidFinishPlaying:(AVPlayerItem *)sender {
    [self.players removeObjectForKey:sender];
}
@end
