ld:找不到文件:链接器命令失败,退出代码为1

Question

在Xcode中构建项目时出现以下错误:

ld:找不到文件

/Users/MacBookPro/Library/Developer/Xcode/DerivedData/Social_Events-cfnteabiivwfdzcoulzznhmgobhy/Build/Products/Debug-iphoneos/Social_Events.app/Social_Events clang:错误:链接器命令失败,退出代码为1(使用-v查看调用)

过去一小时我一直坚持这个错误..任何解决方案？代码在iOS 7和xCode 5.0中运行良好.现在对于iOS8,它给了我这个错误.

使用框架:

• CoreTelephony
• Mapkit
• Facebook.SDK v3.20
• 基础
• CoreGraphics中
• UIKit框架

完全错误:

Answer 1

您可能会收到此错误,因为您重命名了项目并且Tests无法再找到它.这很容易解决:

像这样在Xcode中解决它:

1. 从项目导航器中选择项目.
2. [Your project's Tests]在目标下选择
3. 在General标签下更改Host Application下拉列表
4. 建立并运行.

这个问题发生在我身上,因为我重命名了我的项目,测试再也找不到了.

Answer 2

问题是在重命名产品后,其测试目标仍在寻找以前的应用名称.

选择"测试"目标,然后在"构建设置"中,按以下方式修改TestHost值以对应新产品名称:

$(BUILT_PRODUCTS_DIR)/YourNewProductName.app/YourNewProductName

Answer 3

我通过重命名产品解决了这个问题.

在Application的目标中,选择Build Settings.

在"打包"选项下,您必须将产品重命名为错误中显示的名称.

它解决了我的问题,代码开始编译.我的测试用例也在执行中.

Answer 4

我有一个类似的问题 - 这是因为我使用Cocoapods并打开.xcodeproj文件而不是.xcworkspace文件... doh!
