Question

我正在尝试将Apptentive添加到IOS应用中。已经使用了很多外部库，例如Admob和Google分析。

我跟着this guide跟着这封信，但我不能让它融合。看下面令人讨厌的失败信息：

出了什么问题，我该如何解决？现在已经2天了，我疯了。

eta：如果我在一个更轻量级的项目中遵循完全相同的步骤，它就构建得很好，所以我猜测存在某种冲突。我只是不知道如何解决它。

您尚未向项目添加一些框架。（据推测，CoreText和CoreTelephony）

有关如何执行此操作，请参阅How to “add existing frameworks” in Xcode 4?

Apptentive guide的引用：

要使用ApptentiveConnect，您的项目必须链接到   以下框架：

CoreData
CoreText
CoreGraphics
CoreTelephony
基础
QuartzCore
  StoreKit
SystemConfiguration
UIKit

将库添加到IOS应用程序会导致可怕的构建失败
