我需要做什么？
答案 0 :(得分：1)
我的iPhone 4s iOS 5.0.1似乎有问题 紧急方法是在Cydia中下载应用程序名称respringIcon，当您想要调试时，打开应用程序选择安全模式。应用程序可以在安全模式下调试 ----------- -------------更新 我用越狱来更新iOS 5.1.1，当我从Cydia安装一个软件时，我使用xCode在手机上调试，但是没有人让调试无法正常工作。我认为iOS5越狱已经解决了这个问题！

此页面http://www.alexwhittemore.com/?p=398似乎与您描述的问题相同，答案（来自该页面）似乎是在Backgrounder中设置“覆盖”。
我不知道这意味着什么 - 但这是该页面描述的内容，以解决问题。
与往常一样，“修复”此问题的唯一方法是不使用越狱设备。

我有完全相同的问题，结果发现TruPrint（它似乎已安装）导致XCode调试器出现问题。尝试卸载它，重新启动设备，然后尝试从XCode启动，它应该可以工作。
