Ios 贝宝API错误

我正试图将PayPal API集成到我的iPhone应用程序中，但当我切换到处理它的控制器时，出现以下错误：

-[UIDevice platformType]：发送到实例0xc25ff20的无法识别的选择器 2014-01-23 15:26:57.668 FuzzionStudio[27749:70b]***由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：'-[UIDevice platformType]：未识别的选择器发送到实例0xc25ff20'

还有其他人遇到过这个问题吗

@迈尔斯，你注意到集成说明中的这一点了吗

在项目的构建设置（在目标部分，而不是项目部分）中，将-lc++-ObjC添加到其他链接器标志

---

如果您以前没有注意到这一点，那么现在遵循该建议可以解决您的问题吗？

您的实际代码是什么样子的？抛出

NSInvalidArgumentException

的特定代码是什么？您是否使用自己的

[UIDevice platformType]

或

[UIDevice something]

？显示一些代码。您是否使用框架来执行此操作？框架是libPayPalMobile.a以及其他几个苹果创建的框架。编辑制作请参见上面的代码。Dave，感谢您的帮助。实际上，我已经从那里删除了-ObjC，因为当我将其保留在中时，我得到了以下错误：架构i386的未定义符号：“\u FBTokenInformationExpirationDateKey”，引用自：Parse（PFFacebookTokenCachingStrategy.o）中的-[PFFacebookTokenCachingStrategy cacheTokenInformation:]ld:symbol找不到架构i386的clang:错误：链接器命令失败，退出代码为1（使用-v查看调用）正常。好。在谷歌搜索该错误后，似乎需要FacebookSDK.framework。我不确定是什么需要它，或者为什么需要它，但我把它包括在内，因为它一切正常。谢谢你让我走上了正确的方向。
