我无法突然理解我的应用程序发生了什么。这个错误一直在崩溃。我创建了一个名为Interface的更多试验项目并运行了几次，之后我回去运行我的原始项目。它一直在崩溃。任何人都可以帮助我吗？谢谢

I am not able to understand what happened to my application all of a sudden. It is crashing all the time with this error. I created on more trial project by the name Interface and ran that a couple of times and after it when I went back to run my original project. It is crashing consistently. Can anyone help me with it? Thanks

上面说的是你的XIB指向一个项目中不存在的类。

the above says that your XIB is pointing to a class that does not exist in your project.

在Interface Builder中检查类设置。应将所有视图和对象设置为标准类或属于项目一部分的自定义类。这可能是拼写错误......

In Interface Builder check the class settings. All views and objects should be set to either a standard class or to a custom class that is part of your project. It could be a spelling error...
