Ios7 使用ios 7+；

我正在使用下载的GStreamer.framework（二进制1.4.5）

我可以在部署目标iOS 6.0中运行，但当我尝试在iOS 7.0中运行时，我收到链接错误

以下是我收到的错误：

如何清除此错误。我想在iOS 7+中运行这个

它的库版本问题

添加了

libiconv2.4.0.dylib

而不是

libiconv.dylib

并添加了

libstdc++6.0.9.dylib

而不是

libstdc++.dylib

现在它在ios7中工作得非常好+

谢谢

您必须向我们提供更多信息。什么代码抛出错误？你试图解决什么问题？看起来您的项目中缺少一个库。@拉维，为什么不提供您链接的库？@mhlz:我正确添加了库，它的兼容性问题。我的应用程序在ios 6中运行良好，只有在ios 7中才会显示这些错误
