【问题描述】：

我想使用 Soundcloud API 在我的应用中播放公共声音。在网上进行了一些搜索后，我找到了一种方法，但我无法让我的代码正常工作。这是我尝试播放声音的代码：

    NSString *publicTrackUrlString = @"https://soundcloud.com/miroslav-osipovic/the-cat-empire-the-lost-song";
NSString *urlString = [NSString stringWithFormat:@"%@?client_id=64a52bb31abd2ec73f8adda86358cfbf", publicTrackUrlString];
[SCRequest performMethod:SCRequestMethodGET
              onResource:[NSURL URLWithString:urlString]
         usingParameters:nil
             withAccount:nil
  sendingProgressHandler:nil
         responseHandler:^(NSURLResponse *response, NSData *data, NSError *error) 
             NSError *playerError;
             player = [[AVAudioPlayer alloc] initWithData:data error:&playerError];
             [player prepareToPlay];
             [player play];
         ];

【参考方案1】：

NSString *trackID = @"100026228";
NSString *clientID = @"YOUR_CLIENT_ID";
NSURL *trackURL = [NSURL URLWithString:[NSString stringWithFormat:@"https://api.soundcloud.com/tracks/%@/stream?client_id=%@", trackID, clientID]];

NSURLSessionTask *task = [[NSURLSession sharedSession] dataTaskWithURL:trackURL completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) 
    // self.player is strong property
    self.player = [[AVAudioPlayer alloc] initWithData:data error:nil];
    [self.player play];
];

[task resume];

您可以从解析资源中获取轨道 ID：http://api.soundcloud.com/resolve.json?url=http://soundcloud.com/miroslav-osipovic/the-cat-empire-the-lost-song&client_id=YOUR_CLIENT_ID。
