In some cases, if classes were traversed in a particular order, the class's superclass would already have had
valueForKeyswizzled. In that case,originalValueForKeywould be set toUITextInputTraits_valueForKey. This leads to an infinite loop inUITextInputTraits_valueForKey.The fix is to traverse the class's heritage until a suitable
valueForKey:implementation is found.
