我刚刚升级到xcode 4.0,我不能再部署到iPhone,我得到一个苹果Mach-O链接器错误,它仍然适用于模拟器。

当前回答

按照以下步骤来解决这个问题:

进入项目设置和构建选项卡。搜索“其他链接标志”

双击Release和Change的链接器标志:

 ${TARGET_BUILD_DIR}/libCordova.a to ${BUILT_PRODUCTS_DIR}/libCordova.a

对调试也执行相同的操作吗 重新清理并建立档案。

其他回答

我对同样问题的解决方案:在“项目”中添加“其他链接器标志”,而不是在“目标”中。 我把它移到了目标,它不应该在项目里。

我有这个问题,导入QuartzCore修复了它。

对我来说,这是不小心导入了一个实现。”M”文件,而不是相应的头文件“。h”文件。当我发现项目构建恢复正常时。

使用CocoaPod,首先安装,然后打开工作区,而不是CocoaPod网站上指定的项目。

$ pod install

$ open YOUR_PROJECT_NAME.xcworkspace

一种可能:在Xcode 4构建设置中打开“死代码剥离”。

另一种可能性是:对于以前使用GCC的某些框架,您可能切换到使用LLVM。回到GCC(或LLVM GCC)可以消除这些警告。
