Ios 如何在UITableView中获取视频文件路径？（tmp目录）

我正在UITableView中显示tmp目录的内容，但无法获取每个单元格的文件路径

当按下该单元格时，我的应用程序应使用MPMoviePlayer播放该文件，但不会

这就是我到目前为止所做的：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {


NSString *tmpDirectory = NSTemporaryDirectory();
fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:tmpDirectory error:nil]; //nsarray

NSString *movieURL = [fileList objectAtIndex:indexPath.row];

NSURL *url = [NSURL URLWithString:movieURL];

_moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

[self presentModalViewController:_moviePlayerViewController animated:YES];
}

NSlog提供了视频的名称，但没有提供路径。由于睡眠不足，我觉得我已经想得太多了。

当你使用这个：

NSString *movieURL = [fileList objectAtIndex:indexPath.row];

NSString *movieURL = [tmpDirectory stringByAppendingPathComponent:[fileList objectAtIndex:indexPath.row]];

NSURL*url = [NSURL fileURLWithPath:movieURL];

它将只返回临时目录中的文件名， 所以用这个：

NSString *movieURL = [fileList objectAtIndex:indexPath.row];

NSString *movieURL = [tmpDirectory stringByAppendingPathComponent:[fileList objectAtIndex:indexPath.row]];

NSURL*url = [NSURL fileURLWithPath:movieURL];

使用此选项时：

NSString *movieURL = [fileList objectAtIndex:indexPath.row];

NSString *movieURL = [tmpDirectory stringByAppendingPathComponent:[fileList objectAtIndex:indexPath.row]];

NSURL*url = [NSURL fileURLWithPath:movieURL];

它将只返回临时目录中的文件名， 所以用这个：

NSString *movieURL = [fileList objectAtIndex:indexPath.row];

NSString *movieURL = [tmpDirectory stringByAppendingPathComponent:[fileList objectAtIndex:indexPath.row]];

NSURL*url = [NSURL fileURLWithPath:movieURL];

更改您的代码，如：

    NSString *tmpDirectory = NSTemporaryDirectory();
    NSLog(@"%@",tmpDirectory);
    NSArray *fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:tmpDirectory error:nil]; //nsarray

    NSString *movieURL = [fileList objectAtIndex:indexPath.row];
    NSString *path=[tmpDirectory stringByAppendingPathComponent:movieURL];

更改您的代码，如：

    NSString *tmpDirectory = NSTemporaryDirectory();
    NSLog(@"%@",tmpDirectory);
    NSArray *fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:tmpDirectory error:nil]; //nsarray

    NSString *movieURL = [fileList objectAtIndex:indexPath.row];
    NSString *path=[tmpDirectory stringByAppendingPathComponent:movieURL];

哇！非常感谢，我真不敢相信我忘记了stringByAppendingPathComponent.wow。非常感谢，我真不敢相信我忘记了stringByAppendingPathComponent。@CokePokes:事实上Midhun议员在我面前给出了正确的答案。答案是在我写答案时加载的，这就是为什么会出现重复。@CokePokes:事实上Midhun Mp在我面前给出了正确的答案。答案是在我写答案时加载的，这就是为什么会出现重复。
