ios - 如何从 iOS 5 的 NSArray 中的文件列表中删除文件扩展名

Question

在 iOS 5 中工作，我从我的文档目录中读取了一个文件名列表，该数组称为“文件列表”。我正在尝试获取不带扩展名的文件名列表。只有我列表中的姓氏删除了扩展名。有什么想法吗？

- (IBAction)getFile:(id)sender
{  
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory =[paths objectAtIndex:0];
    NSArray *fileList = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil];
    NSString *names = [[[fileList valueForKey:@"description"]componentsJoinedByString:@"\n"]stringByDeletingPathExtension];

    NSLog(@"File Name Is \n%@",names);    
    showFile.text = names; 
}

    NSString *names = nil;
    for (NSString *name in fileList){
        if (!names) names = [[name lastPathComponent] stringByDeletingPathExtension];
        else names = [names stringByAppendingFormat:@" %@",[[name lastPathComponent] stringByDeletingPathExtension]];
    }
    NSLog(@"File Name Is \n%@",names
