Have a look at the documentation for -writeToFile:atomically: In
particular this quote:
"This method recursively validates that all the contained objects are
property list objects (instances of NSData, NSDate, NSNumber,
NSString, NSArray, or NSDictionary) before writing out the file, and
returnsNO if all the objects are not property list objects, since the
resultant file would not be a valid property list."
What is your real goal? Do you want a plist where the Error key is an
archived NSError object, or just an archived version of the
dictionarty? I'm going to guess the former in which case you would
change your code to do:
[dict setObject:[NSKeyedArchiver archivedDataWithRootObject:error]
forKey:@"Error"];

Hello to mac developers :)
If I don't misunderstand things NSError objects can be archived
because NSError implements NSCoding protocol.
I try to archive it as follows:
NSMutableDictionary * dict = [[NSMutableDictionary alloc] init];
NSError * error = [[NSError alloc] initWithDomain: @"TestDomain"
code: 1 userInfo: nil];
[dict setObject:error forKey:@"Error"];
[dict setObject:@"OperationName" forKey:@"Operation"];
[dict writeToFile:@"/Users/ivira/temp" atomically:YES];
Without placing error into dict it work's ok. What am I doing wrong?
