[英]iOS 7 migration help - Runs in Simulator, but not on device — app does not load

原文 2013-09-21 21:52:50 9 1 iphone/ ios/ objective-c/ xcode/ ios7

Disclaimer: I'm helping out on another developer's code (he didn't have the time and the customer wants it fixed quickly) and so I'm not totally familiar with this code. 免责声明：我正在帮助其他开发人员的代码（他没有时间，客户希望快速修复它），所以我对这个代码并不完全熟悉。

So the app is built for iOS 6, is in the App Store, and runs great. 因此，该应用程序是为iOS 6构建的，位于App Store中，并且运行良好。 Until you try opening it on a device running iOS 7 GM. 除非您尝试在运行iOS 7 GM的设备上打开它。 You see the splash-screen for a moment, then it crashes completely. 您看到启动屏幕片刻，然后完全崩溃。 This is causing problems because none of our users can use the app anymore after updating. 这引起了问题，因为更新后我们的用户都无法使用该应用程序。

I just got the source code and I have been trying to figure it out. 我刚刚获得了源代码，并且一直在努力弄清楚。 It compiles fine, and even runs in the iOS 7 simulator. 它可以很好地编译，甚至可以在iOS 7模拟器中运行。 (Although, of course, the UI needs to be redesigned for iOS 7.) （尽管，当然，需要针对iOS 7重新设计UI。）

Here's where it gets weird: when I run it on my iPhone 5 (iOS 7) from Xcode, the app hangs (just like with the App Store version, of course) -- but it's just so weird, considering that in runs in the Simulator. 这就是怪异之处：当我从Xcode在iPhone 5（iOS 7）上运行它时，该应用程序挂起（当然，就像App Store版本一样），但是考虑到在模拟器。

Good news is that I have some runtime errors that might help to track down the problem. 好消息是，我遇到了一些运行时错误，可能有助于找出问题所在。 I ran a search that indicates it could be a missing connection in a xib file, but I didn't find one. 我进行了搜索，表明它可能是xib文件中缺少的连接，但没有找到。

Here is the log. 这是日志。 If it helps, I can also include the build warnings. 如果有帮助，我还可以包含构建警告。

I really have no idea what is going on. 我真的不知道发生了什么。

Any help would be greatly appreciated :) 任何帮助将不胜感激：）
