我试图启用解析崩溃报告。但是，编译时始终存在链接器错误。我在其他线程中尝试过该方法，比如添加除libstdc ++ 6之外的libstdc ++ 6.0.9。
错误消息是：

这些是在另一个没有链接到应用程序的框架或静态库中吗？
答案 1 :(得分：0)
该链接错误意味着您正在使用PFDevice，PFLogger和PFRESTAnalyticsCommand类，但您没有链接任何提供这些类的实现的目标文件，库或框架。您需要在构建时添加链接。如果使用Xcode，请选择提供类的框架，并选中该框以将其添加到目标（或将其拖到链接阶段）。你已经链接它，消息也可能意味着你的框架没有x86_64切片。

将最新版本Parse.framework，ParseCrashReporting.framework和Bolts.framework重新添加到您的项目中。
答案 3 :(得分：0)
我解决了这个问题。 问题实际上是由buildPath中的库路径不正确引起的。所以xcode首先搜索路径并使用Parse.framework的订单版本
