在我的ios应用程序中,我需要将放在/ var/mobile/Library/Preferences/xxx中的存档解压缩到例如/ var/mobile/Library/Preferences/tmp中.

我的问题是,当我启动它时:

unzip /var/mobile/Library/Preferences/xxx/archive.zip -d /var/mobile/Library/Preferences/tmp/

在tmp文件夹中,有所有归档路径:/ var/mobile/Library/Preferences/tmp/var/mobile/Library/Preferences/xxx/archive/...

我怎么能只为/ var/mobile/Library/Preferences/tmp/archive/...而不是所有存档路径进入目标目录？

播放音频时是否可以更改AVPlayerViewController实例的背景？

当我锁定我的设备时,我可以看到正确显示专辑图片的音乐控件,但是当我的应用程序中显示AVPlayerViewController时,我只能看到具有代表当前正在播放的QuickTime的背景的控件.

以下是我的称呼方式:

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];


        NSURL *url=[NSURL fileURLWithPath:clickedPath];
        AVPlayer *player = [AVPlayer playerWithURL:url];


        AVPlayerViewController *controller = [[AVPlayerViewController alloc] init];
        [self presentViewController:controller animated:YES completion:nil];
        controller.player = player;
        [player play];

我的java程序中有三个按钮可以播放三种不同的声音.看看我的代码:

    import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.io.File;
import java.io.IOException;
import javax.sound.sampled.*;
import java.awt.datatransfer.*;
