昨天我的应用程序正在部署（调试版本）到iPad。但是今天我升级到了iOS 4.2.1（即当前版本），现在它在控制台上吐了很多废话，并且在最终运行应用程序之前挂起了不确定的时间（有时是几分钟或更长时间）设备。
任何人都可以对这种行为有所了解吗？我该如何摆脱它？
PS看最后一行：
/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/System/Library/CoreServices/Encodings/libJapaneseConverter.dylib
到底是怎么回事？在我的应用程序或我生命中的任何其他地方，我与日语没有任何关系。我的硬盘上有几部很棒的吉卜力电影，但就是这样。

您可以手动删除相应的符号目录。然后插入设备，打开管理器，告诉Xcode加载该设备的符号。
答案 1 :(得分：0)
重启一切。运行Xcode然后连接您的设备。等到它完成复制符号之后再做任何事情。应该这样做！
答案 2 :(得分：0)
重新安装SDK修复了它。
注意我还通过按住yonks的两个按钮并让iTunes将最新的iOS放在其上来将我的设备设置为恢复模式
编辑：只是与IRC上遇到同样问题的其他人交谈 - 他通过从/Developer/Platforms/iPhoneOS.platform/DeviceSupport/中删除他的符号文件夹来解决它......可能比重新安装一切更聪明一些^^就是菲利普上面所说的！
