Question

我刚刚安装了XCode 4并且遇到了一些麻烦。当我使用IOS 4.2在iPad上运行新项目时，应用程序在启动之前崩溃了。如果我然后单击该应用程序的图标，它会打开并运行正常。是什么赋予了？为什么不通过调试器？在升级到版本4之前，我从未遇到过XCode的这些问题。

我从控制台得到的错误低于要求：

有什么想法吗？

Answer 1

我刚尝试在我的同事iPhone上运行相同的项目，它运行良好。所以我的iPad出了问题。猜猜所有这些错误代码意味着我需要擦拭我的iPad并恢复。其他人有这种经历吗？

Answer 2

我遇到了同样的问题，并且非常生气，我开始在Xcode4上试图修复它。

我找到了解决此问题的方法，方法是单击“设备选择”下拉菜单，然后选择底部的编辑方案。然后，您将启动选项更改为“等待[此处的应用名称] .app启动”

但是，当您运行时，您必须单击设备上的应用程序图标。每次。至少它有效。

祝你好运！

在设备上调试时，XCode4应用程序在启动时总是崩溃
