通过获取SIGABRT错误更新为Xcode5模拟器

Question

An app I recently started and working its keeps crashing with a SIGABRT message. The general message at the top of the debugger says:

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIView 0xb651580> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key parentEmail.'

... At the the bottom it says:

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb)

Let me know if the "first throw call stack" info is necessary to solve this one.

Answer 1

Usually this comes from an outlet link inside a xib with no corresponding class variable. Did you remove a variable from a class without removing the link inside the xib?

Answer 2

Check and make sure that you didnt previously have a button/text field/label previously linked with an action, then deleted that item. The link still exists. Check and make sure that all your links match to existing items.
