硬盘要挂的节奏，准备新硬盘吧
硬盘坏道多了，
建议下载专业检测硬盘的工具 自己检测下
百度上有免费软件
可以再blos关闭的
百度看一下 自己关闭就行
登录百度帐号推荐应用买的时候在卖家那里安装了一些免费应用，但是好像用的是他们的apple&ID,昨天自己注册了一下，同步的时候之前他们给安装的应用不小心全都移除了。然后到苹果商店免费下载一些应用如QQ、汤姆猫等，但是同步的时候出现了两种错误提示：【应用程序未被安装到ipad上，因为发生未知错误0x8008001】和【应用程序未被安装安装到ipad上，因其资源已被修改】特此求助解决办法
有种思念叫望穿秋水，有种寒冷叫忘穿秋裤。
这些软件是要你重新安装的，下载IPAD的软件会和你的苹果ID绑定而不是和设备绑定。之前安装的软件是和商家的苹果ID绑定的，所以只有商家的ID才能使用，你用自己的ID重新装一遍软件就可以了。
Re:[小蛮腰舅舅,2楼]&就是绑定了自己的ID之后下载安装时出现的提示错误，目前还没解决。

会报空指针异常。

if (e.getSource() == jb1) {
ad = new AddDialog();//弹出窗体，然后这里是不往下执行，只有窗体不显示了才往下执行。所以在弹出的时候，界面内操作时,ad还没有赋值完成，是null,你可以这句话前后加print看看执行过程
你确定时ad空指针错误么？我运行了你的代码，把你没有提供的类注释掉后，可以完成你想要的操作。这是我运行的代码，没有异常，贴代码挺好的，但是贴异常信息最重要。

整个代码只有UserManagerClick里会初始化ad
如果直接执行AddDialogClick，ad就是null
AddDialog 没有实例化
