崩溃"未找到符号:_OBJC_CLASS _ $ _ NSMutableURLRequest"

Question

我已经在iOS 3和iOS 7.1.1的调试模式下安装了我的应用程序Xcode 5.1.1,如下面的崩溃日志所示.在安装应用程序的一天工作正常.我没有使用我的iPad 2天,今天它只是在Splash屏幕上崩溃,第一秒.重启iOS没有帮助.

任何想法为什么会发生？为了以防万一,我会将CFNetwork和Foundation框架重新添加到我的项目中,但也许是其他的东西？可能是iOS中的一个错误？

尝试重新添加Foundation.framework:

1. 转到项目的目标
2. 选择"常规"选项卡
3. 在"Linked Frameworks a Libraries"下查找Foundation.framework,选择它并按下buttom上的减号(' - ')以删除此框架.
4. 现在按加号('+')并搜索Foundation.framework - 重新添加它,它应该可以修复你的崩溃.

希望它有效 - 它确实适合我.
