我已将录制的音频存储在应用的“文档”文件夹中。当我将录制的文件传递给活动控制器时,它总是返回nil,我收到以下错误:
[__ NSPlaceholderArray initWithObjects:count:]:尝试从对象插入nil对象[0]
我的代码:
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
NSString *path = [DOCUMENTS_FOLDER stringByAppendingPathComponent:[fileList objectAtIndex:[indexPath row]]];
NSURL *audioURL = [NSURL URLWithString:path];
NSData *audioData = [NSData dataWithContentsOfURL:audioURL];
self.activityViewController = [[UIActivityViewController alloc]
initWithActivityItems:@[audioData] applicationActivities:nil];
[self.activityViewController setValue:@"Recording" forKey:@"subject"];
[self presentViewController:self.activityViewController animated:YES completion:nil];
任何帮助?

好的。通过更改
来管理解决NSURL *audioURL = [NSURL URLWithString:path];
NSData *audioData = [NSData dataWithContentsOfURL:audioURL];
self.activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[audioData] applicationActivities:nil];
到这个
NSURL *audioURL = [NSURL fileURLWithPath:path];
self.activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[audioURL] applicationActivities:nil];
希望这可以帮助其他有类似问题的人。
