I would like to be able to add additional context info to certain exceptions
that the system might generate. Since NSException's userInfo dict is nil in
such cases it would be convenient to add an error context dict to the exception
and then handle/display it.
@try {
...;
}
@catch (NSException *e) {
e.userInfo = [NSDictionary dictionaryWithObject:@"Unsupported session
resolution"
andKey:@"Context"];
--> No setter method "setUserInfo:" for assignment to property
[ self showException: e ];
}
@finally {
...;
}
Unfortunately I can't just add my own userInfo dict onto the exception, as
there is no setter for it by default. Would it be heresy to create an
NSException category to implement the -setUserInfo: method to do this? What is
a better way to handle this?
