NSAlert takes a format string. Therefore you must take care to never
ever pass user input as part of the format string.
NSString *fullString = managedObj.fullString;
NSString *informativeText = [NSString stringWithFormat:@"The
fullString %@ is invalid.", fullString];
NSAlert *alert = [NSAlert alertWithMessageText:…
informativeTextWithFormat:@"%@", informativeText];
Note the use of "%@" as the format argument.
