将应用程序部署到 iPad 时出现奇怪的控制台消息

Question

昨天我的应用程序正常部署（调试版本）到 iPad。但今天我升级到了 iOS 4.2.1（即当前版本），现在它在控制台上吐出很多废话，并挂起一段不确定的时间（有时是几分钟或更长时间），然后才最终运行该应用程序设备。

谁能解释一下这种行为？我该如何摆脱它？

PS看看最后一行：

/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/System/Library/CoreServices/Encodings/libJapaneseConverter.dylib

到底发生了什么？我的应用程序或生活中的其他任何地方都与日语无关。我的硬盘上有几部很棒的吉卜力电影，但仅此而已。

Answer 1

您可以手动删除相应的符号目录。然后插入您的设备，打开管理器，并告诉 Xcode 加载该设备的符号。

Answer 2

重新启动一切。运行 Xcode 然后连接您的设备。等到它完成复制符号后再执行任何操作。应该这样做！

Answer 3

重新安装SDK修复了它。

注意，我还通过按住 yonks 的两个按钮将我的设备设置为恢复模式，然后让 iTunes 在其上安装最新的 iOS

编辑：只是与 IRC 上遇到相同问题的其他人交谈 - 他通过删除他的/Developer/Platforms/iPhoneOS.platform/DeviceSupport/ 中的符号文件夹...可能比重新安装所有内容更聪明。

^^ 即菲利普上面所说的！
