应用程序在iPhone 5s上运行，但在iPhone 4s上运行

Question

我在iPhone 5s上使用Xcode 6 beta和iOS 8，iphone 4s是标准的ios 7.1手机。

该应用程序在iPhone 5s上运行良好，但只要尝试iphone 4s或iPhone 4s模拟器。 应用程序爆发并抛出以下错误

  

dyld：未找到符号：_NSURLAuthenticationMethodClientCertificate     参考自：/ Users / MIkeAspinall 1 / Library / Developer / CoreSimulator / Devices / xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx / data / Applications / xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx / WeddingsAndMore.app / WeddingsAndMore     预期在：/Applications/Xcode6-Beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/System/Library/Frameworks/CFNetwork.framework/CFNetwork    in / Users / MIkeAspinall 1 / Library / Developer / CoreSimulator / Devices / xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx / data / Applications / xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx / WeddingsAndMore.app / WeddingsAndMore   （lldb）

我不确定为什么会这样。但iPhone 5s模拟器抛出同样的错误。它似乎只能在iOS 8上运行。

为ios 7.1手机设置了设置 我也使用parse.com进行数据访问

我的手机是iphone 5s运行ios 8 beta

iphone 4s正在运行ios 7.1

模拟器在xcode 6beta中运行

app设置为在ios 7.1或更高版本上运行。 我正在使用xcode 6beta 希望能清除我所拥有的东西
