我正在尝试在下载时从 iTunes 商店播放这首歌
为什么下面的代码不播放?
NSLog(@"start");
NSURL *songUrl = [NSURL URLWithString:@"http://a1804.phobos.apple.com/us/r1000/064/Music/v4/9b/b3/c7/9bb3c7dc-a06f-f18c-3e41-2ce1e36f73b4/mzaf_7432104896053262141.aac.m4a"];
NSError* errorVar = nil;
AVAudioPlayer* song = [[AVAudioPlayer alloc] initWithContentsOfURL:songUrl error:&errorVar];
[song prepareToPlay];
[song play];
