将库添加到IOS应用程序会导致可怕的构建失败

Question

我正在尝试将Apptentive添加到IOS应用程序中.已经有相当多的外部库被使用,例如Admob和Google分析.

我按照这个指南来写这封信,但我不能让它融合.看到下面讨厌的失败信息:

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.

您还没有为项目添加一些框架.(据推测,CoreText和CoreTelephony)

有关如何执行此操作,请参阅Xcode 4中的"如何添加现有框架"？

Apptentive指南引用:

要使用ApptentiveConnect,您的项目必须链接以下框架:

CoreData
CoreText
CoreGraphics
CoreTelephony
基础
QuartzCore
StoreKit
SystemConfiguration
UIKit
