调试时，应用程序在iOS 8中崩溃，但在未调试时可正常运行
[英]app crashes in iOS 8 when debugging, but works when not debugging
问题描述
此应用在iOS 7模拟器上运行正常，没有任何问题。 但是，当我在iOS 8.1模拟器上调试它时，它崩溃了。 它甚至不会到达第一视图控制器的viewDidLoad。
编译器离开applicaitondidFinishLaunchingWithOptions：之后，方法应用程序崩溃。
但是我可以在iOS 8.1模拟器中运行已经构建的应用程序，而不会出现任何问题。 仅当我通过Xcode运行应用程序时崩溃。 可能是什么原因？ （考虑到它已经在iOS 7中很好地调试了）？
