好的，我有iPad的应用程序阅读杂志。所有以前的问题都可以。我设法做出新的问题（在其他人离开公司之前完成）并在模拟器和设备上运行它没有问题。
现在我在数据库中为杂志的新版本添加行并通过ZIP工具压缩所有图片和多媒体并将其划分为MacHacha（因为从MacHacha上传需求部分的Java类逐个上传）并将其上传到服务器上。在App商店我下载了杂志，可以看到新的问题。在服务器上，新行具有良好的所有参数，并且大小足以在磁盘上调整大小。
当新问题芬兰语下载时，它会显示错误。我从模拟器和OUTPUT尝试了相同的程序，它崩溃的那一刻显示我的解压缩错误（0）。
我认为问题在于将部件与MacHacha放在一起。任何人都可以帮助或给我解决这个问题的捕获。
如果它有帮助我可以上传新问题并提供链接（它是免费的）我会对你们这些人和女孩有所帮助:)）

申请链接。在图书馆中几乎没有问题，最后一个是新的（Giugno 2011）。
我将提供该方法的代码，该代码为我提供错误的字符串：
