iOS AVAudioPlayer播放音频时，已经将音频下载了本地，怎么还出现下面的错误啊

Posted 2023-03-09

Error Domain=NSOSStatusErrorDomain Code=1954115647 "The operation couldn’t be completed. (OSStatus error 1954115647.)"

这是我的代码：
//将数据保存到本地指定位置

NSString *urlStr = [self.audioArray objectAtIndex:sender.tag];

NSLog(@"urlStr === %@",urlStr);

NSURL *url = [[NSURL alloc]initWithString:urlStr];

NSData * audioData = [NSData dataWithContentsOfURL:url];

NSString *docDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

NSString *filePath = [NSString stringWithFormat:@"%@/%@.arm", docDirPath , @"temp"];

[audioData writeToFile:filePath atomically:YES];

//播放本地音乐

NSError *error = nil;

NSURL *fileURL = [NSURL fileURLWithPath:filePath];

player = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];

if (player == nil)

NSLog(@"error === %@",[error description]);



player.delegate = self;

[player play];

参考技术A 你试一下我的代码，这段代码可以工作。
NSData *audioData = [NSData dataWithContentsOfURL:someURL];
NSString *docDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:@"%@/%@.mp3", docDirPath , fileName];
[audioData writeToFile:filePath atomically:YES];

NSError *error;
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];
if (player == nil)
NSLog(@"AudioPlayer did not load properly: %@", [error description]);
else
[player play];
追问

谢谢你的答案，但是我这边还是报错：
Error Domain=NSOSStatusErrorDomain Code=1954115647 "The operation couldn’t be completed. (OSStatus error 1954115647.)"
真是够灰心的，就简单的十几行代码，却怎么整，都是错
