如何通过NSData播放audio？
我转换了这个path（文件：//localhost/var/mobile/Applications/8F81BA4C-7C6F-4496-BDA7-30C45478D758/Documents/sound.wav），这是一个audio文件即录制的。
我将此path转换为NSData。
NSData是：例如：
<00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 64617461 1cf50200 32003200 e2ffe2ff 3cff3cff 08fe08fe 44fe44fe 04fe04fe e6fde6fd 95fd95fd 96fe96fe b9feb9fe ........................................................................................................................f7fef7fe 96ff96ff bdffbdff d6ffd6ff 92009200 23012301 b200b200 79007900 5c015c01 fe01fe01 f101f101 fc01fc01 7b027b02 36023602 > 我想玩这个NSData，
我喜欢下面
NSString *urlString = [[NSString alloc] initWithData:appDelegate.dataTestingWasteData encoding:NSUTF8StringEncoding]; NSURL *url = [[NSURL alloc] initWithString:urlString]; self.palyer=[[AVPlayer alloc] initWithURL:url]; [self.palyer play];
但没有播放，urlString打印为空。
相同path(file://localhost/var/mobile/Applications/8F81BA4C-7C6F-4496-BDA7-30C45478D758/Documents/sound.wav)
正在玩，如果我们使用下面的代码：
-(void)playAudio { if (!audioRecorder.recording) { stopButton.enabled = YES; recordButton.enabled = NO; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioRecorder.url error:&error]; audioPlayer.delegate = self; if (error) NSLog(@"Error: %@",[error localizedDescription]); else [audioPlayer play]; } }
NSString *urlString = [[NSString alloc] initWithData:appDelegate.dataTestingWasteData encoding:NSUTF8StringEncoding]; NSURL *url = [[NSURL alloc] initWithString:urlString]; NSData *wavDATA = [NSData dataWithContentsOfURL:url]; NSError *error; self.player=[[AVAudioPlayer alloc] initWithData:wavDATA error:&error]; [self.player play];
