Apple Mach-O Linker错误,我不知道该怎么做

Question

我不能再为设备或模拟器编译我的项目了.我得到13个Apple Mach-O-Linker错误.这一切都是在我尝试使用sharekit失败后开始的.这是错误的日志:

我该如何解决？请帮忙.

Answer 1

对于每个有类似错误的人.如果发生这种情况,您通常可以删除Point下的"Path"

target-> Build Settings-> Library Search Paths

Answer 2

将框架多次添加到项目时,可能会发生此错误.

• 您可以通过删除副本来解决此问题.要找到它,请在Xcode项目导航器中选择框架,然后选择在Finder中显示.然后清理并构建您的项目.

如果您缺少框架头文件或对它们的引用,也可能导致这种情况.

• 在这种情况下,您应该尝试删除SDK或框架并再次添加它.

祝好运.

Answer 3

如果您使用的CocoaPods安装的依赖,确保你点击你打开你的XCode项目.xcworkspace文件,而不是该.xcodeproj文件.

Answer 4

看来项目文件可能已以某种方式损坏。

解决此问题最可靠的方法是创建一个新项目，并将文件和旧的 info.plist 移到其上。

解决此问题的下一个最可能的方法是在当前项目中创建一个新目标，并查看它是否可以编译（如果您有旧目标中的任何特殊标志，您将需要复制它们）。

此外，您还可以尝试针对发布版与构建版进行编译，如果其中之一有效，请查看所有编译器选项，看看有什么不同。

如果您为 Sharekit 添加了标头搜索路径，也许可以尝试清除整个标头搜索路径，看看是否可以解决问题。还要确保您的项目仍然包含全新项目包含的框架（UIKit 和 NSFoundation，可能还有其他）。
